There are zero in the Marketplace.
Is there some kind of technical limitation of Android that prevents this most rudimentary of features of a computing device with a screen? I just don't get it at all. It can't be that nobody has asked for one. So there must be a limitation of Android that prevents a screenshot from being generated?
REQUEST: Can anyone write an app that solves this? I think there were would be great demand.
I think if it was possible, there would be one by now. Most likely it's not.

I think you answered your own question; )
In order to take a screen print, data from the video RAM must be extracted. root access is required for this.

Yeah, you can pretty much rule out anything that requires direct access to hardware. Hardware access is limited to what is accessible via APIs. By the look of it, that does not include access to the video RAM. There are many other things (flashlight for example) which, although they seem simple, are not included in the standard APIs and therefore are not possible without root access to the device.

Thank you. I'm not a developer so I didn't know these limitations existed. This OS has developed so fast -- less than 2 years old... and yet, I would have thought this kind of thing would have been handled long ago, just from end-user expectation: "I can print-screen" or screen grab on my full size computer, so i probably can screen grab from my hand held computer.
But re flashlight -- maybe there is one specific function/app you are referring to, but on my Hero, unrooted, thru the Market, i must have downloaded and tried about 6 different flashlights, all with basic function of using the white light of the screen as a light source... some that enabled you to change the color of the screen to blue, red, etc... One even has this cop-car alternating red-blue flashing light display.
I am probably misunderstanding you though.
I think ultimately I am just surprised certain things are not further along -- and it's a stark contrast to a thread I was just visiting way across the other side of the XDA forums universe -- called WP7 - epic fail --- in which many die hard WM developers lament the passing of an OS that gave amazing levels of access to devs, yet the UI of the OS itself was beyond dated, it was dysfunctional and impractical in today's world.
It's just interesting to read the perspectives of developers touting Symbian as the most open OS and most efficient (less battery drain) -- and last I knew I thought it was being killed off. Wrong again.
I'm extremely happy with Android -- but then there are these few blindspots where I have to say -- wow -- i could do THAT 5 years ago on my old T-Mobile MDA WM 5x phone ... like 100%-reliable voicetags for phone calling contacts, opening apps etc, vs speech recognition, ... like the abilities the resistive screen gave me in drawing elaborate sketch at a meeting -- or my being able the take really quick notes with -- yes -- a stylus -- not an alltogether stupid idea -- and have a 90% success rate at character recognition and conversion to text ... the precision of controlling a color slider bar on a resistive screen --- i understand that's not OS but screen properties -- but I am just collectively observing that while I absolutely loved my HERO, and now am discovering my DESIRE, there are still some very basic things I can't do with allegedly the best smartphone in the marketplace.
I'm very agnostic about hardware and software, never been a fanboy -- I'm a usability designer... so functionality rules, end users rule. And basic things like this -- a screenshot -- they may be very explainable by devs... And my question may sound like it's very annoying to some, and I'm just a dumb **** (not you, you were respectful), but I think, as a end user advocate, it's pretty stupid -- and seems senseless to me that this phone can do 1001 backflips with video, and yet it can't let me "record" what I see on my screen. I get it that it's not yet released by Google, but they're who I'm calling stupid for not solving something so elementary by now.
I have every right to say this without any android architecture knowledge.
I can see your point, but in all modern operating systems, there is no direct hardware control, for any purpose, no matter how benevolent the purpose might be.
This is done only through api programming and libraries of calls, which are also restricted most of the time.
The reason is simple and can be summarized to one word, security.
As phones are becoming more and more capable of doing sensitive activities like online banking transactions and on top of that hold every personal info one has,
security will become an even greater concern.
Windows so far, have been the least secure platform for every day use to date. This is also true for windows mobile.
I know it looks like you are getting less usability than you did, but at least in this case its not just to inflate someone's wallet with extra money, through proprietorial lock down of services and apis, which would be "opened" at a later date for some more cash.
I m sure that in no time we ll be seeing full blown firewalls and antivirus suites for superphones like the desire.
All it will take is a few more viruses-trojans targeting mobile platforms like jailbroken iphones or rooted android devices.
I guess the same limitations are to be blamed for not having a proper voice recorder, i.e. one that can record both parts of a phone conversation.
reason you arent getting a non root screenshot app(if memory serves correctly):
the screenshot app takes a dump of the display file in /dev/ and then uses image processing to output a jpg/png/whatever. At the momment we can see the contents of /dev/ with (adb shell ls /dev/) but any attempt to read/write/copy (adb pull /dev/lightsensor ./lightsensor)(yes i know that is the light sensor but couldnt remember what the display file was called) anything is met with a "permission denied".

Do terms like ‘Android ROM’ confuse you? Is your understanding of ‘flashing’ limited to acts of exhibitionism? Do you feel left out or clueless when your friends talk about flashing the latest custom ROM to their Android device ? here is a guide for you to make your life easier
Hey guys, this is a guide which will help many people (new users).
The Very Beginning!
Android is an Operating System (OS), like Windows or OSX to your computer or iOS [1] to the iPad and iPhone. It controls how the phone reacts to your inputs, what's displayed on the screen and when. Many would argue, the OS is the most important factor of any mobile device. Whether or not you agree, it certainly has a massive impact on user experience, hopefully at the end of this, you'll be able to make up your own mind.
Note-
Red color means -> its important !!

Understanding ROM’s and Builds
A ROM is essentially a custom version of Android. Each tweaks, combines, or optimizes Android to offer something standard versions lack. Within ROM’s, you have what are known as builds (basic branches of Android code) that offer certain features and characteristics.
Think of it as a crude metaphor for Microsoft Windows. There’s XP, Vista, and Windows 7. All three are Windows operating systems and can typically run the same programs, but there are major differences between them. Within each OS, there’s further distinction between Vista Home, Vista Pro, and Vista Ultimate. Likewise, one ROM can spawn multiple versions. For instance, there are several flavors of Drake’s Hero ROM..
Be advised that some ROM’s require a wipe (erases all information stored on your phone) before or after installation. This is done when you enter the recovery mode and perform a “factory data reset.”
What is Firmware?
The read-only operating systems that we just discussed above are also called ‘firmware’, as they stay firmly in place without modification access to the users of the device. Modification of firmware is still however possible, just not under normal usage. Many devices require specialized hardware to be used for the purpose while other devices have the storage set as read-only through software protection only, which can be removed or overridden without the need for any specialized hardware, just by using software written for the purpose, often but not always requiring connection to a computer.
Thus, the terms ‘operating system’ and ‘firmware’ both refer to the same thing and can be used interchangeably when applied to such devices.
Flashing
The ROM memory used in smartphones and tablets etc. is often same as flash memory found in SD cards and USB flash drives, simply optimized for better speed and performance while running the operating system. As explained above, it is read-only under normal usage and requires a special procedure for any modifications to be made to its contents. The procedure of modifying or replacing the contents of such flash memory is known as flashing. Thus, in layman’s terms, flashing is essentially the same as installing or modifying the firmware of a device that is stored on its protected flash memory.
2 – Mobile Operating Systems
ROM as the Operating System
When it comes to smartphones and tablets, the term ROM is used to refer to the firmware stored in the internal memory of the device, rather than the internal memory itself. It can also refer to a file prepared for the purpose of replacing this firmware with another version of using a special method.
Thus, when you are told by someone to download a ROM, they are referring to the file that contains the firmware in a format ready to be installed to your phone to replace it’s existing firmware. Similarly, when asked what ROM is your phone running or when told by someone their phone is running a particular ROM, they are again talking about the particular variant of the firmware.
Types of ROMs->
Unlike most desktop operating systems, mobile operating systems can be found in installable format in multiple forms, which can be categorized as follows.
A)Truly Stock ROMs / firmware:
This is the operating system in its default form, without any modifications made to it except for any device-specific support required to run it on the particular device. Truly stock firmware provides the standard user experience of the operating system without any cosmetic or functional changes made.
B)Manufacturer or Carrier branded Stock ROM / Firmware:
This type of firmware has had enhancements added over the default operating system by the device manufacturer or the mobile service carrier. This often includes interface enhancements, proprietary applications and in most cases, restrictions intended to limit the use of the device with a specific carrier or region. There are often further restrictions preventing installation of firmware not released by the carrier or manufacturer.
C)Custom ROM / firmware:
Independent developers who like to customize their devices beyond the standard options provided often tend to release the fruits of their labor for the rest to enjoy, in form of custom ROMs.
3 – Stock Vs. Custom ROMs
Both stock and custom ROMs have their merits and demerits and choosing between the two requires careful consideration. In this section, we are going to make a comparison between the two types of ROMs to help you make the right choice. Let us begin by taking a look at their advantages and disadvantages.
Advantages & Disadvantages of Stock ROMs
Stock firmware is the result of a lot of research and testing done by the operating system vendor, the device manufacturer and/or the mobile service carrier. Therefore, it carries several advantages:-
1>It is usually quite stable upon release.
2>Almost all bugs are patched during the extensive beta testing before release.
3>It carries the official support by the firmware vendor, device manufacturer and the mobile service carrier.
4>Updates are pushed automatically to the device by the carrier.
Along with its advantages, stock firmware also carries its disadvantages and these include:
1>Updates aren’t frequent, as development is done mostly by corporations who have to follow a scheduled release cycle.
2>Providing feedback to the manufacturer in case of any issues is either impossible, unwelcome (often with Apple devices), or a long, tedious process.
3>Similarly, getting official support can be a hassle as well, involving a tedious process.
4>If the device manufacturer and operating system developer are different (as is the case with Android and Windows Phone 7), any updates released by thekoperating system vendor need to be edited by the device manufacturer or mobile carrier to add compatibility and additional software before release. Hence, some devices get updates delayed by months.
5>Updates are often released first in the United States, leaving the rest of the world waiting. (A world does happen to exist beyond the United States, we’ve confirmed it ourselves!)
6>Worse still, when manufacturers choose to no longer release official updates for their older devi#es in favor of newer ones, their users are essentially stuck with old versions of the operating system. This case is evident with many Android devices barely a year and a half old.
Advantages & Disadvantages of Custom ROMs-
Custom ROMs are as good or as bad as the effort put into them by their developers. Key advantages of custom ROMs are:
1)First and foremost, choice! There are thousands of custom ROMs out there for a range of devices, each offering a diverse set of features not found in the stock ROM.
2)Update frequency – custom ROMs are often under active development and newer releases of the core operating system are incorporated in them way before updated official ROMs are released.
3)Providing feedback is as easy as leaving a message on the development forum for the ROM in question.
Getting support with your issues at the forums is similarly easy, as not only the main developers themselves but also other experienced users of the ROM from the community are glad to help you with your issues and in the process, improve the ROM for everyone.
4)Custom ROMs usually have all the extra restrictions removed
5)Performance enhancements and optimizations found in many custom ROMs can make them much faster than stock ROMs ,enabling users to get the most out of their devices.
5)Overclocking options are built into some custom ROMs, further speeding up the devices.
6)Undervolting options found in some ROMs on the other hand result in improved battery life.
7)Old phones with little internal memory can benefit most from custom ROMs that allow them to use the external SD card memory for the apps exactly the way they would use the internal memory.
So with all these advantages, there should be no reason to stick with the stock ROM, right? Not necessarily! Like all things in life, custom ROMs come with their disadvantages as well:
1)Due to the lack of extensive testing prior to release, many custom ROMs can be buggy in the beginning and installing a ROM with missing or corrupt critical files can even brick your phone.
2)Several custom ROMs that are ports of ROMs from other phones can have missing functionality that hasn’t been made to work on your phone with the ROM yet.
Installing a custom ROM usually involves wiping your phone to factory settings, so you lose your data and start from scratch. Fortunately, Android’s built-in contact syncing along with apps offering message, call log and app backup/restore make this process easier, letting you retain your data.
The installation process can be cumbersome and requires you to root your phone and often circumvent its security features to allow for custom ROM installation in the first place.
Installing a custom ROM will in most cases void your phone’s warranty, though often the process is reversible, meaning you can turn your phone back to stock as long as it isn’t bricked.
Choosing the Right Custom ROM
With several custom ROMs available for most Android devices, choosing the right one isn’t always easy. The question of ‘which is the best ROM for _____ phone / tablet’ is as often frowned-upon at the forums as it is asked, since there is no universal answer for it. One ROM may be the best for me while another might suit you better. The only solution is to read a lot, go through the feature list, read user response and if required, ask the developer questions at the forum page for the ROM. Attempt to install the ROM only after you are fairly satisfied that doing so will not harm your device to the extent you can’t fix.
Nandroid BACKUPA Nandroid Backup is a backup file of your current ROM and its settings, you can do it manually using Clockwork Mod Recovery, it's fairly intuitive so you shouldn't have too much issue figuring these steps out.*IMPORTANT*
RISKS OF ROOTINGWhen a root exploit is initially found, it may or may not be stable. What this means is that it may not work reliably, or worse, it may cause a permanent failure of the phone, preventing it from booting up. A responsible phone hacker will therefore test the exploit extensively across many phones and modify the exploit as needed to make it stable. When the exploit has been proven to work safely and reliably, it is released to the public. However, this does not guarantee that the exploit will work with every single phone that it targets. The person or team that releases the exploit will make it clear that the exploit is "use at your own risk." Each person considering rooting their phone needs to understand this risk and decide whether it's worth proceeding or not.
Once the exploit has removed the NAND protection, the risk of permanently damaging your phone becomes very, very low. That's not to say that you can't get yourself into a bind, but with a little bit of know-how, rarely does a bad situation mean a bricked phone. If you haven't guessed already, a bricked phone is a phone that shares the qualities of a brick: it can look rectangular and do nothing.
As a preemptive safety measure, the custom recovery program installed as part of the root exploit contains a very useful tool called a NANDroid backup/restore. This utility backs up your internal memory and essentially is a save-state. No matter how you change your phone in the future, you can always bring your phone back to the state it was in at the time of the backup. It is highly recommended to make a NANDroid backup before flashing anything.
Knowledge is power here. If you've read this far, you already have a really good foundation into the Android rooting world. For more excellent infor-ation, I recommend reading this post: Quick INTRO TO ROOTING for those new to rooting, which will give you a broader vocabulary of root-related terminology. The more information you gather, the more you will realize that the risks of rooting are very low, while the rewards are very high.
And don't hesitate to use these forums to ask questions and seek clarifications. The rooting community is strong, and there are tons of people eager to help. Today's newbies are tomorrow's experts. Good luck in your endeavor%r1
The Android Family Tree
Android has a come a long was since its birth in 2008, however we're not here to fire into its history specifically, but what its history might mean for you! Android has been released in incremental versions. Each phone may differ in what version it has installed, usually the vendor decides what version it will choose, and develops Android into a specific ROM [2] for the device. To find out what version of Android your device is, navigate to the settings menu and select 'about phone', under 'Android version' there will be three numbers, the first two, will tell you what release you're running. There are currently 5 flavours of Android for phones, these are;
1.5 - Cupcake
One thing you'll learn, Android has quirky names! This version of android is likely the most basic version you'll meet, very few handsets still selling have this version. If you have a handset with version 1.5, you're limited in a big way! There are many features missing that means 1.5 just can't support many of the applications offered up in the market!
1.6 - Donut
Donut offered a few improvements over Cupcake; Voice search, turn-by-turn navigation and an improved market to name a few! It's still missing a few features that don't allow the more advanced apps to run. So don't be suprised if you're missing a few from the market.
2.0/2.1 - Eclair
Google picked up their game with the move to 2.1, it is arguably the largest and most important update Google made. Most applications will work on 2.1! It also included support for Microsoft exchange (if you don't know what this is, you don't need it) increased speed, smoothness, and improved the user interface immensely.
2.2 - Froyo
Currently the largest version in use, you're with a masses here and perhaps will find comfort in it. a few performance tweaks, faster browsing and the ability to run Adobe Flash 10.1 is among the few things you can do over your 2.1 bretheren.
2.3/2.4 - Gingerbread
Updated UI, higher resolution screens, VoIP calls, improved keyboard, introduced NFC to the world, faster performance, and a better battery life are among the benefits over your older bretheren. This released also improved voice-to-text engine input, copy and paste, audio effects, and enabled simultaneous multiple camera support.
4.0 - Ice Cream Sandwich
Ok huuuge update here, haven't played on it yet but this is shaping up to be the biggest update since 2.1, if not ever! Combining Gingerbread and Honeycomb, this is loooking a very mature and slick version of Android. Massive UI overhaul; hardware acceleration, no physical/permanent buttons, new Roboto font, Honeycomb task manager, new screen layouts, easily customisable folders, widget app drawer and a customisable launcher. Other improvements include new contacts or 'people' app, further improved copy and paste, further improved keyboard, visual voicemail with improved functionality, improved gestures, new lock screen, integrated screenshot capture, facial recognition unlocking, Android Beam utilising NFC, and awesome 3g data management software!

How does one flash a kernel?
The process is a simple as flashing a ROM, put the .zip on ur sdcard, go into recovery,wipe cache,dalvik-cache, install .zip from sdcard, reboot phone and ur done.
How to Flash A Custom ROM-
Download a ROM of your choice from the All Things Root section (The Forum you are in) You can find direct links to each of them in the All Things Root Guide that is stickied at the top of this forum.
1- Once downloaded, its recommended to download it from your computer and place it on your phone, put it on the root of your internal or external sd cards. Root meaning not in a folder.
2- Reboot into recovery using Quick Reboot.
3- Using your volume keys to scroll and your power key to select, scroll down tand select "Wipe data/Factory Reset" then scroll to "Yes" and select.
4- Scroll down and select "Wipe Cache Partition" and then select "Yes"
5- Scroll down and select "Advanced" and select "Wipe Dalvik Cache" and then select "Yes" then scroll down and select "Go Back"
6- Sroll down and select "mounts and storage" then scroll down and select ONLY these 3 listed, "format data" and then select "Yes", then scroll down and select "format cache" and then select "Yes", then scroll down and select "format system" and then select "Yes". Then scroll down to and select "Go Back"
7- Then scroll down to "Install Zip From Sd", if you put the ROM on your external SD card select "choose zip from SD". If you put it on your internal scroll down and select 'choose zip from internal". Then after you selected one of those depended on where you put the ROM, scroll down and select the ROM and then Select "Yes".
Let it run and do its thing and once it says its done, select "reboot system now" and enjoy
How To Flash A Theme-
Download a theme of your choice from the All Things Root section (The Forum you are in) You can find direct links to each of them in the All Things Root Guide that is stickied at the top of this forum.
1- Once downloaded, its recommended to download it from your computer and place it on your phone, put it on the root of your internal or external sd cards. Root meaning not in a folder.
2- Reboot into recovery using Quick Reboot.
3- Using your volume keys to scroll and power button to select, scroll down and select "wipe cache partition" and then select "Yes"
4- Scroll down to and select "Advanced" and then select "Wipe Dalvik Cache"
5- Then scroll down and select "Go Back"
6- Then scroll down to "Install Zip From Sd", if you put the theme on your external SD card select "choose zip from SD". If you put it on your internal scroll down and select 'choose zip from internal". Then after you selected one of those depended on where you put the theme, scroll down and select the theme and then Select "Yes".

-------------------*Important Tips*---------------------
--- Important Tips ---
[1]THERE IS NO SUCH THING AS THE *BEST* ROM OR *BEST* TWEAKS
-everything that has *best* in it's name is mainly made by questioner's preference.
[2] STOP ASKING FOR ETA'S....Stop asking when will it be released or when will that be released.its silly you know. IT WILL COME WHEN ITS READY GET IT ?
[3]OK this will be quite simple. If it says DEVS ONLY leave it alone. Don't comment unnecessary trash and ask for ETA's.
It's unstable so don't go making a thread in general section asking if it's stable or not.ok ?
[4]RESPECT THE DEVELOPERS*IMPORTANT*
[5] Read or search before posting anything! GOOGLE is your best friend!
https://www.google.com (use me)
SEARCH SEARCH SEARCH SEARCH BEFORE DOING SOMETHING !!!!!
I hope i am clear.....
[6] Stop posting and posting the same stuff over and over and over again! If it says in the ROM description that ""This" is not working" Dont keep on asking is "this" working? or something like that.
[7] Post in the proper section. You will get more help if you do this.
For example... don't start a question thread in developers forum just because you think it's more active than general section. EVERYTHING HAS IT'S PURPOSE
[8] If a bug has been reported once,then THATS ENOUGH REPORTING < Read once more,enough said
[9] LOOK,READ AND THEN ONLY POST,If there is something you want to post,then look at thread,read the whole thread and then ONLY post.

Android Terms,Slang & Definitions*Important* + How to Increase Battery Life !
PART #1
Android Terms,Slang & Definitions
Apps2SD:A method of storing applications and cache on the device's microSD card.
ADB:Android Debug Bridge (adb) is a versatile command line tool that lets you communicate with an emulator instance or connected Android-powered device. It is a client-server program that includes three components:
•A client, which runs on your development machine. You can invoke a client from a shell by issuing an adb command. Other Android tools such as the ADT plugin and DDMS also create adb clients.
•A server, which runs as a background process on your development machine. The server manages communication between the client and the adb daemon running on an emulator or device.
•A daemon, which runs as a background process on each emulator or device instance.
AMOLED:Active Matrix Organic Light Emitting Diode. Basically, a very colorful, bright, display found in some smartphones.
APK:Android application package file. Each Android application is compiled and packaged in a single file that includes all of the application's code (.dex files), resources, assets, and manifest file. The application package file can have any name but must use the .apk extension. For example: myExampleAppname.apk. For convenience, an application package file is often referred to as an ".apk".
Alpha:The alpha phase of the release life cycle is the first phase to begin software testing (alpha is the first letter of the Greek alphabet, used as the number 1). In this phase, developers generally test the software using white box techniques. Additional validation is then performed using black box or gray box techniques, by another testing team. Moving to black box testing inside the organization is known as alpha release.[1]
Alpha software can be unstable and could cause crashes or data loss. The exception to this is when the alpha is available publicly (such as a pre-order bonus), in which developers normally push for stability so that their testers can test properly. External availability of alpha software is uncommon in proprietary software. However, open source software, in particular, often have publicly available alpha versions, often distributed as the raw source code of the software.
The alpha phase usually ends with a feature freeze, indicating that no more features will be added to the software. At this time, the software is said to be a feature complete.
Boot Animation:Boot animation is a term for a graphical representation of the boot process of the operating system.
Boot animation can be a simple visualisation of the scrolling boot messages in the console, but it can also present graphics or some combinations of both.
Unlike splash screens, boot screen or boot animation is not necessarily designed for marketing purposes, but can be to enhance the experience of the user as eye candy, or provide the user with messages (with an added advantage of color coding facility) to diagnose the state of the system.
Bootloader:This small program's only job is to load other data and programs which are then executed from RAM.Often, multiple-stage boot loaders are used, during which several programs of increasing complexity load one after the other in a process of chain loading.
Bootloop:When your system recycles over and over without entering the main OS.
Beta: is the software development phase following alpha. It generally begins when the software is feature complete. Software in the beta phase will generally have many more bugs in it than completed software, as well as speed/performance issues. The focus of beta testing is reducing impacts to users, often incorporating usability testing. The process of delivering a beta version to the users is called beta release and this is typically the first time that the software is available outside of the organization that developed it.
The users of a beta version are called beta testers. They are usually customers or prospective customers of the organization that develops the software, willing to test the software without charge, often receiving the final software free of charge or for a reduced price.
Beta version software is often useful for demonstrations and previews within an organization and to prospective customers. Some developers refer to this stage as a preview, prototype, technical preview (TP), or early access.
Some software is kept in perpetual beta—where new features and functionality is continually added to the software without establishing a firm "final" release.
CPU:It stands for Central Processing Unit and handles all the complex mathematical formulas necessary to do everyday things like surfing the Internet.
Cache:A component that transparently stores data so that future requests for that data can be served faster. The data that is stored within a cache might be values that have been computed earlier or duplicates of original values that are stored elsewhere. If requested data is contained in the cache (cache hit), this request can be served by simply reading the cache, which is comparatively faster. Otherwise (cache miss), the data has to be recomputed or fetched from its original storage location, which is comparatively slower. Hence, the greater the number of requests that can be served from the cache, the faster the overall system performance becomes.
CDMA:Mobile phone standards called cdmaOne, CDMA2000 (the 3G evolution of cdmaOne) and WCDMA (the 3G standard used by GSM carriers), which are often referred to as simply CDMA, and use CDMA as an underlying channel access method.
CIQ:Carrier IQ. A piece of preinstalled software that runs with elevated access in the background of portable devices by default and records everything. Potentially can be exploited to steal information.
Dual Core:A dual core processor is a central processing unit (CPU) that has two separate cores on the same die, each with its own cache. It essentially is two microprocessors in one. This type of CPU is widely available from many manufacturers. Other types of multi-core processors also have been developed, including quad-core processors with four cores each, hexa-core processors with six, octa-core processors with eight and many-core processors with an even larger number of cores.
Dalvik:The Android platform's virtual machine. The Dalvik VM is an interpreter-only virtual machine that executes files in the Dalvik Executable (.dex) format, a format that is optimized for efficient storage and memory-mappable execution.
Dalvik Cache:Writable cache that contains the optimized bytecode of all apk files (apps) on your Android device. Having the information in it's own cache makes applications load faster and perform better.
EXT2:The ext2 or second extended filesystem is a file system for the Linux kernel. It was initially designed by Rémy Card as a replacement for the extended file system (ext).
ext2 was the default filesystem in several Linux distributions, including Debian and Red Hat Linux, until supplanted more recently by ext3, which is almost completely compatible with ext2 and is a journaling file system. ext2 is still the filesystem of choice for flash-based storage media (such as SD cards, and USB flash drives) since its lack of a journal minimizes the number of writes and flash devices have only a limited number of write cycles. Recent kernels, however, support a journal-less mode of ext4, which would offer the same benefit along with a number of ext4-specific benefits.
EXT3:Third extended filesystem, is a journaled file system that is commonly used by the Linux kernel. It is the default file system for many popular Linux distributions, including Debian. Stephen Tweedie first revealed that he was working on extending ext2 in Journaling the Linux ext2fs Filesystem in a 1998 paper and later in a February 1999 kernel mailing list posting, and the filesystem was merged with the mainline Linux kernel in November 2001 from 2.4.15 onward.Its main advantage over ext2 is journaling, which improves reliability and eliminates the need to check the file system after an unclean shutdown. Its successor is ext4.
EXT4:It was born as a series of backward compatible extensions to ext3, many of them originally developed by Cluster File Systems for the Lustre file system between 2003 and 2006, meant to extend storage limits and add other performance improvements.However, other Linux kernel developers opposed accepting extensions to ext3 for stability reasons,and proposed to fork the source code of ext3, rename it as ext4, and do all the development there, without affecting the current ext3 users. This proposal was accepted, and on 28 June 2006, Theodore Ts'o, the ext3 maintainer, announced the new plan of development for ext4.
FC/FC's:Short for "force close," meaning an app that has crashed.
Fastboot:A diagnostic protocol used primarily to modify the flash filesystem in Android smartphones from another computer over a USB connection. It is part of the Android Debug Bridge library.
Utilizing the Fastboot protocol requires that the device be started in a boot loader or Second Program Loader mode in which only the most basic hardware initialization is performed. After enabling the protocol on the device itself it will accept any command sent to it over USB via a command line. Some of most commonly used fastboot commands include:
•flash - Overwrites a partition in flash with a binary image stored on the host computer.
•erase - Erases a partition in flash.
•reboot - Reboots the device into the either the main operating system or the system recovery partition.
•devices - Displays a list of all devices (with Serial #) connected to the host computer.
Flashing:The ROM memory used in smartphones and tablets etc. is often same as flash memory found in SD cards and USB flash drives, simply optimized for better speed and performance while running the operating system.
Hotspot:A spot that offers Internet access over a wireless local area network through the use of a router connected to a link to an Internet service provider. Hotspots typically use Wi-Fi technology.You can connect wifi campatible devices to it.
HDMI:High-Definition Multimedia Interface) is a compact audio/video interface for transmitting encrypted uncompressed digital data.It is a digital alternative to consumer analog standards, such as radio frequency (RF) coaxial cable, composite video, S-Video, SCART, component video, D-Terminal, or VGA (also called D-sub or DE-15F). HDMI connects digital audio/video sources (such as set-top boxes, DVD players, HD DVD players, Blu-ray Disc players, AVCHD camcorders, personal computers (PCs), video game consoles (such as the PlayStation 3 and Xbox 360), AV receivers, tablet computers, and mobile phones) to compatible digital audio devices, computer monitors, video projectors, and digital televisions.
JIT:The Just-in-Time Compiler. Released with Android 2.2, it's a method of greatly speeding up apps in Android on the software side.
Kang:Someone writes a code,someone else modifies the code to make their own release,its concidered a kang release.
Kernel:A kernel is a layer of code that allows the OS and applications to interface with your phone's hardware. The degree in which you can access your phone's hardware features depends on the quality of code in the kernel. The homebrew (rooting) community for HTC has made several kernel code improvements that give us additional features from our hardware that the stock kernel does not. When you flash a custom ROM, you automatically get a kernel. But you can also flash a standalone kernel ROM on top of the existing one, effectively overwriting it. These days, the difference in custom kernels is less about new features and more about alternate configurations. Choosing a custom kernel is basically choosing one that works best with your ROM.
Launcher:Collectively, the part of the Android user interface on home screens that lets you launch apps, make phone calls, etc. Is built in to Android, or can be purchased in the Android Market.
LCD Density:Pixel density is a measurement of the resolution of devices in various contexts; typically computer displays, image scanners, and digital camera image sensors.
First of all you need to understand that the Android User Interface uses something called a "display independent pixel" or a "dip" (yes, it's confusing because the density settings are in "dots per inch" or "dpi" which are considered the same as "ppi" or "pixels per inch" as well).
The default LCD Density setting on Android is 160 dpi. As far as the operating system is concerned 1 dip @ 160 dpi = 1 screen pixel. It doesn't mean that's actually true, but you've gotta start somewhere. In my opinion it would have been a lot nicer if they'd chosen 100 dpi because then it would be an easy percentage thing, but they didn't so we're stuck with this formula.
Mod:The act of modifying a piece of hardware or software or anything else for that matter, to perform a function not originally conceived or intended by the designer.
Nightly:A build that is performed at the end of each day of development. If you use a continuous integration server, it will generally be configured to build the code and run the unit tests on every check in. At the end of each day you may want to run more extensive tests, regression test and integration tests for example, which take too long to run on each check in and these would be triggered after the nightly build. If you have a full continuously delivery pipeline the nightly build may also be used to deploy the built code to environments for user testing.
Open GL:An open source 3D graphics library used in many devices, including Android devices.
Open & Closed Beta:Developers release either a closed beta or an open beta; closed beta versions are released to a select group of individuals for a user test and are invitation only, while open betas are from a larger group to the general public and anyone interested. The testers report any bugs that they find, and sometimes suggest additional features they think should be available in the final version.
Overclock:To increase the speed of your CPU.
Partition:The phone's internal memory (not the SD card) is solid-state (flash) memory, AKA NAND. It can be partitioned much like a normal hard drive can be partitioned. The bootloader exists in its own partition. Recovery is another partition; radio, system, cache, etc are all partitions.
Here are the standard partitions on an Android phone:
/misc - not sure what this is for.
/boot - bootloader, kernel
/recovery - holds the recovery program (either clockworkmod or RA recovery for a rooted Evo)
/system - operating system goes here: Android, Sense, boot animation, Sprint crapware, busybox, etc
/cache - cached data from OS usage
/data - user applications, data, settings, etc.
The below partitions are not android-specific. They are tied to the hardware of the phone, but the kernel may have code allowing Android to interact with said hardware.
/radio - the phone's radio firmware, controls cellular, data, GPS, bluetooth.
/wimax - firmware for Sprint's flavor of 4G, WiMax.
PRL:The Preferred Roaming List, basically a way of telling your phone which towers to connect to first.
RUU:a complete software package released by HTC, it can contain many things they are trying to update. Radio, ROM, bootloader, etc... Installing an ruu is like installing an image on a hard drive it wipes the phone and installs the image. It will wipe everything data and all so if you install one be prepared.
Radios:On the HTC side of things,the radios persist of:
•WiFi, which operates at 2.4-5ghz depending on what channel it's running
•Cellular/3G, which carries voice and data
•4G/WiMAX, which only carries data
•GPS, which is receive-only
•Bluetooth, which talks to WiiMotes and headsets
Flashing a radio means updating the code that controls the phones way of sending and recieving a signal.
Root:The first level of a folder.
SBC:(the ability to charge your battery beyond the default safe limit). The concept is similar to overclocking a processor: you're overriding the safety limits established to achieve additional performance. The benefit here is that you may gain more use of your battery per charge. The drawback is that you can damage the battery and significantly reduce its longevity. Some kernels claim they are using a safe technique to prevent battery damage. Just be aware of the potential risks.
Sideloading:It means installing applications without using the official Android Market.
Splash Screen:A splash screen is an image that appears while android is loading.Splash screens cover the entire screen or simply a rectangle near the center of the screen. The splash screens of operating systems and some applications that expect to be run full-screen usually cover the entire screen.
Superuser/SU:On many computer operating systems, the superuser is a special user account used for system administration. Depending on the operating system, the actual name of this account might be: root, administrator or supervisor.
Normal work on such a system is done using ordinary user accounts, and because these do not have the ability to make system-wide changes any viruses and other malware - or simple user errors - do not have the ability to adversly affect a whole system. In organizations, administrative privileges are often reserved for authorized experienced individuals.
Script:The Scripting Layer for Android (abridged as SL4A, and previously named Android Scripting Environment or ASE) is a library that allows the creation and running of scripts written in various scripting languages directly on Android devices. SL4A is designed for developers and is still alpha quality software.
These scripts have access to many of the APIs available to normal Java Android applications, but with a simplified interface. Scripts can be run interactively in a terminal, in the background, or via Locale.
SDK:(SDK or "devkit") is typically a set of software development tools that allows for the creation of applications for a certain software package, software framework, hardware platform, computer system, video game console, operating system, or similar platform.
Stock:This is the operating system in its default form, without any modifications made to it except for any device-specific support required to run it on the particular device.
S-On:Security on,means no acces to the phones operating system.
S-Off:Security was exploited,now have access to the operating system.
Tethering:Means sharing the Internet connection of an Internet-capable mobile phone with other devices. This sharing can be offered over a wireless LAN (Wi-Fi), Bluetooth, or by physical connection using a cable. In the case of tethering over wireless LAN, the feature may be branded as a mobile hotspot.The Internet-connected mobile phone acts as a portable router when providing tethering services to others.
USB:Stands for Universal Serial Bus. Is a method of connecting devices to a computer. Most smartphones now use microUSB cables to charge and sync.
Updater Script:When Android devices install updates via 'update.zip' files using recovery mode they have to perform a wide range of functions on files and permissions. Instead of using a minimal shell such as {b,d,c}sh the Android designers decided to create a small functional language that can be extended by device manufacturers if necessary. Since the Android "Donut" release (v1.6) the scripting language is called Edify and is defined primarily in the bootable/recovery/{edify,edifyscripting,updater} directories of the Android source-code tree.
Wireless N:Wireless N technology increases wireless internet connection. Wireless 'N' routers also work with Wireless 'G' and 'B' wireless adapters.
WiiMax:(Worldwide Interoperability for Microwave Access) is a communication technology for wirelessly delivering high-speed Internet service to large geographical areas.
YAFFS:Yaffs1 is the first version of this file system and works on NAND chips that have 512 byte pages + 16 byte spare (OOB;Out-Of-Band) areas.[clarification needed] These older chips also generally allow 2 or 3 write cycles per page,which YAFFS takes advantage of - i.e. dirty pages are marked by writing to a specific spare area byte.
Newer NAND flash chips have larger pages, 2048 bytes + 64 bytes spare areas, and stricter write requirements.Each page within an erase block (128 kilobytes) must be written to in sequential order, and each page must be written only once.YAFFS2 was designed to accommodate these newer chips.YAFFS2 is based on the YAFFS1 source code,with the major difference being that internal structures are not fixed to assume 512 byte sizing,and a block sequence number is placed on each written page. In this way older pages can be logically overwritten without violating the "write once" rule.[clarification needed]
YAFFS is a robust log-structured file system that holds data integrity as a high priority.A secondary YAFFS goal is high performance.YAFFS will typically outperform most alternatives.It is also designed to be portable and has been used on Linux, WinCE, pSOS, eCos,ThreadX and various special-purpose OSes.A variant 'YAFFS/Direct' is used in situations where there is no OS, embedded OSes and bootloaders: it has the same core filesystem but simpler interfacing to the OS and NAND flash hardware.
Zipalign: An archive alignment tool introduced first time with 1.6 Android SDK (software development kit). It optimizes the way an Android application package (APK) is packaged. Doing so enables the Android operating system to interact with the application more efficiently, and hence has the potential to make the application and overall the whole system much faster. Execution time is minimized for zipaligned applications, resulting is lesser amount of RAM consumption when running the APK.

PART #2How to increase battery of Your Tab !
While many of us, and our readers, are seasoned vets of the Android ecosystem, there are many that are just starting out. After spending the last hour looking for something to cover that was extreme, I had an idea. That idea is what you are seeing here. A newbie friendly series of posts that will outline various topics from the simple, to the more complex. Not always about some new root tool, some new device or some insane kernel. More focused on basic daily operations, things that can improve upon the newest users experience to the Android ecosystem.
In today’s newbie guide we are going to outline a few battery saver tips and tricks that can help extend the life of your battery.
Tip #1 - As much as we all love the look of live wallpapers, they suck battery. Sticking to a static, or regular picture, will help out. Alternatively, the best option for many devices is using a true black png image. This is particularly helpful on AMOLED based screens, as color pixels use power where as black does not. Click the link to head to a black png, long press on it and save it. Then apply it as your wallpaper. If you can set it as a lockscreen wallpaper too that would be a good idea.
Tip #2 – Cut back on the widgets. While widgets are pretty, fun and often times useful, over doing it can hurt you long-term. Not just in battery performance, but even device performance. For instance, using Beautiful Widgets, you can get the date, time and weather in one widget versus running three different ones. If you can’t live with out them, then at least adjust the settings for when they update. Instead of polling the weather every time you turn your screen on, set it to every 4 or 8 hours. Most widgets will also let you set them to only pol manually. While it might be a slight inconvenience, pulling data for updates uses power and it uses your data plan.Similar rules apply to apps like Hootsuit, Facebook and so on.
Tip #3 – Screen brightness can dramatically affect your overall battery life. Many devices have an auto brightness setting that will use your light sensor to adjust the brightness according to the current lighting conditions. It is recommended that you leave that turned on. I have found that while it is nice, I prefer to have manual control of my brightness. If you spend a great deal of time indoors, the lowest brightness setting is enough to see your screen and use your phone. While the next statement might seem to contradict the widget tip, not all widgets consume power. Most Android version have a ‘power control’ widget which gives you quick access to WiFi, Bluetooth, GPS, Sync and brightness. If your device doesn’t have one, you can locate single button widgets that offer the brightness control, such as this one. I personally keep it to the lowest setting and if I need more light, just tap the brightness button to make it brighter when I need it.
Tip #4 - This one is simple and easy. Keep Wi-Fi and GPS off unless you actually need them. Both are easily controlled with the power control widget ro any other number of apps to keep you from having to go through the settings all the time. Heck, many newer devices even have those in the notification drop down bar now.
Tip #5 – When traveling or staying in an area that has no reception, turn of the devices radios. Sounds silly right? But if you are somewhere that gets no service at all, your device is going to be constantly searching for service and your battery is going to drain like crazy. The easiest and most universal way to turn of your radios is to put the device in ‘airplane mode.’ That is generally under Menu > Settings > Wireless and Networks. Although some UI’s have it in a different location and there are also apps and widgets that can accommodate this function. This also works out well in an office environment where Wi-Fi might be present but cell service is non existent. You might need to toggle the Wi-Fi back on for data use, but your phone won’t be searching for cell connection the whole day either.
Tip #6 – Adjust your screen off time. Many of us seasoned vets just hit the power button when we are done on our phone to turn of the screen. While it is rare, some devices don’t have that option. Setting the screen off time to the lowest amount of time will help ensure your phone’s screen goes off in case you forget. Believe me, I have seen people set their phone down with the screen on for hours and wonder why their battery dies so quickly. This can be accessed via Menu > Settings > Display. Depending on your current device, it might be screen off timer or sleep. Maybe others, not sure.
Tip #7 – This tip has a few various parts. First, running your battery through a few charge cycles is always a good idea. This means fully charging the device, then running it until it powers off. While it is off, plug in and charge it to 100%. Then repeat the process at least twice, but three times is a good idea. Sadly, the batteries the manufacturers use, aren’t always of the highest quality. Bummer huh.
Tip #8 – Watch for ‘rogue’ apps. By that we mean, if you have recently installed an application and you have noticed that your battery life has also recently gotten worse, you may have a rogue app running. This is usually pretty easy to find by checking Menu > Settings > Battery. You can usually see what apps are sucking juice. If you locate one, you can kill that process to stop it from eating battery, or if it is an app you hardly use simply uninstall it.
Tip #9 – Final tip for this post. Your launcher. Yes, your current launcher might be the culprit as well and you may not even know it. The fantabulous Sense UI found on HTC devices, TouchWiz found on Samsung devices and MotoBlur found on Motorola devices can also attribute to battery brain. Often times switching to a new launcher such as Go Launcher EX, ADW Launcher EX or countless other launchers can provide not only a boost in battery performance, but also a boost in your devices speed. Not to mention the added benefit of fun UI elements, themes and tweaks.
While there are plenty of other tips and tricks that I am sure our readers will add to the comments, these are 9 that can really make a difference in your daily consumption. Give them a try if you haven’t already done so and give it a couple of days. Nothing happens over night.

yes , you are right... there is not much in the development section ,it can be due to since its new tablet . hope it gets better.
Thanks for putting all this together... haven't read through it all yet as I think it probably covers a lot of what I know and have learnt since I joined the Android world last year, but I will bookmark it so I can point friends this way if they leave the iPhone flock.

Thumbs Upz! This is amust read and priority post before u go to other topics.
Help
Great Post!
Please I know I am most likely in the wrong area or post, I have had a Desire HD before and been down the road of rooting and flashing roms on it, I now own a Galaxy tab 7.7 and feel as if this is all new for me again. unfortunately I am in South Africa and had bought my tablet online, I was not told it would be a Arabic region tablet. Could I please ask who to speak to or ask for help on roms, I have the build number (HTJ85B P6800JPKL4) and want to know what roms will work and what not to use on this.
Please, I know you guys have better things to worry about but your advise or help would be gladly appreciated
Thank you in advance!

I'm going to use it to educate myself.
I'm going to use it to write a High performance micro kernel (i will later fix up for cortex-A8, HD2 ) and for testing the ARMASM code i write, (which i currently test on my only phone, HD2 and it's painful to do so thanks to HTC's SPL, MPU, NAND fatigue and the fact that i need it working the next day).
It has Thumb (2) support so i will try my hand at that too, thumb2 promises quite a lot of code density with somewhat the same performance.
Also I'd be porting the Little Kernel to it, which already has support for cortex-M3
I'll use it to make the word a better place........just joking ......mass destruction awaits if i get that........so don't give it to meh.
Basically because I have no idea how to use a development board, I'm gonna use it to learn how to use one and also learn to code which is something I have been looking into. So yeh....
i will use it to develop a better wireless usb card. i already have one. a arthos 2255. i would like to mod these too together for use with any O.S. my idea would be that you just plug and play. kida like a gui. you plug it in and a window comes up and you can see the progress of it emulating it self into your system O.S and any hardware without internet. might have to put bigger a storage device. but it can be done.. AND I WILL DO IT!
Nerdie stuff
Well im going to mod my phone and learn how to be a android developer
I want to add it to my LEGO collection >
I am joking around ... I love u developers
I'm going to find out what it is.
Unboxing video and then blend it
Sent from my XT910 using Tapatalk 2
What I'll do with it...
I would try and create a WiFi cracker with it by connecting a WiFi midule to it and also try to run the Android OS on it, and finally I would do some home automation on it, DLNA and remote controlling various things.
Please hit thank you!
I really really want this...
I will build full framework that connects your Discovery to internet (home network => public IP, if you have one), runs web server, gathers data from all over the house via NRF24L01-based wireless network (another small ATTiny based modules with humidity, temperature, .. sensors, controlling lights and power etc) and provides them on web page.
I would give it one of the devs for the lg optimus thrill/3d because I'm not a dev but it would probably help development for my device greatly and mabie we could get some good stuff going on this phone
I would use it to play around with android.

Click to collapse
Hahaaha, I'm in the same boat with you
I would use it to develop a custom AOSP-based image for use as a low-cost media tablet, with IR, DLNA, Remote Control and a TV tuner for the ultimate lounge room accessory.
A Real Car-puter
I would use it, in conjunction with an application board, to build a carputer...not one that allows you to listen to or watch pirated media. One which will automate things such as wipers and headlights. For the wipers, my car has only one intermittent setting so I would like to add in more settings. Maybe also look into rain sensors at some point but not initially. Headlights will be controlled by time (automatically coming on at night)and light sensors to turn on lights during daytime hours when lighting conditions are poor or if I am driving through a tunnel). Also use speed limit information hacked from gps maps to light up my dash gauges with different colours depending on my current speed and the posted speed limit (Red > 5% over speed limit, green for 10% under to 5% over the speed limit blue > 10% under the speed limit and no colour for missing speed limit information.
I know the usage is light for such a board but it leaves room for expansion and the projects I have here seem to be a good starting point for learning with.
Future projects could include controlling things such as ignition, doors and windows, heating etc from my phone and eventually building a customised alarm system. Also, some sort of laser mounted to a servo that will project a line/image onto the road to give following drivers a guide to what distance they should be from you depending on the speed you are travelling.
Good luck to everyone that enters.
First, I would learn how to use it then use it to get the Robitics merit badge(im in scouts) and show other scouts how to do it. I would also integrate it somehow into my science project that will help people(still have some planning to do :/) for school.
Good Luck
I'm going to use it to build a giant robotic Obama
im going to use it for education and i will be using it for my 2 final years of high school making automated systems in my engineering and IT Classes!
