New Project Android Project - Android Software Development

I need to develop an app to scan a bar code for event tickets.
Which phone/camera or version of Android would be the fastest at this? Which version should I develop for?
Thank you

On my tests of a G1 camera and a Nexus one, they are equally fast. The fastest way is to use http://code.google.com/p/zxing/
Just call the application (barcode scanner, need to be installed) from yours via an intent. There is a way to make sure that the barcode scanner app is installed, and if not, just prompt the user to install it.
About the version, here you can check how many devices are running a certain version:
http://developer.android.com/resources/dashboard/platform-versions.html
For a barcode scanner app you could aim for 1.5 to get maximum compatibility.

[Q] Question about android plarform and app developing

Hi,
I'm using Motorola Milestone. A lot of times I have to update a new version of an app which has several bug fixes for Nexus One. As I know that the Milestone and Nexus One are running the same Android OS version (2.1). I just wonder why a normal application (such as Calendar or Note) must be dependent on hardware? I mean the same application version that works on Milestone but some of its features don't work in the Nexus. Let's take an example of Windows OS. We can install Firefox, Winamp or even some low level interacting program like anti virus in any computer (Lenovo, Acer,...) as long as they're running the same Windows version (like Vista). Is it a down side of Android platform?
I think I have a similar question. On my work the have a winmo databas app that work like an workordersystem. Can this program run in Android by any chance or has it to be rewritten to work on a Android platform?
I managed to install my application on the SD card by using to apkInstaller.
I thus wanted to test the installation from Android Market... My application does'nt settle down on the SD card but on the telephone... Why ? Nevertheless I added in the manifest the option android:installLocation="preferExternal" !
Needs to make other thing ?
Thank for your answers !
It's mostly localization.
Either developers ask google to make their app available only for certain devices, or certain manufacturers ask google to make only certain apps available.
If an app is built against the SDK, then it's compatible with all devices that share that SDK version.

[Q] Firesheep app for Andriod

Hello all,
Its been a long time no speak on this forum for a while, I have finally made the jump from WM (HTC LEO/SE X1) to Android on a Dell Streak. Admittedly I am still waiting on a stable o2 sanctioned version of Froyo to put SENSE UI on!
My question here relates to Firesheep, an add on for Firefox that allows packet capture on public WiFi networks. I was wondering if anyone could port this application to android as a stand alone App, or if anything else similar had been developed?
I hope someone can give me an answer at least to the feasibility of this request.

I too would love to know hehe

It would require drivers for the wireless chipset in the phone to be put in promiscious/monitor mode to capture packets, as far as I know, neither is possible, unfortunately.

Couldn't it run in firefox mobile
monitor mode in galaxy S
There is an app available in market called pixie who get the promiscuous mode for the wifi interface. I'm able to capture packets in Samsung Galaxy S (GT-I9000) with the app installed.
Now we're waiting for firesheep realease for android... it's impossible to install the XPI in Firefox mobile beta...
Yeah, I tried porting the XPI over to firefox mobile, but it wont work without a packet capture utility, like WinPcap, which is used with the normal Firefox Win version.
I would be definately interested in seeing where this goes though...

It is also working in OSX so I guess libpcap should be enough to use it. By reading this http://seclists.org/tcpdump/2010/q1/98 it seems that there is support for Android. However you will need root access to use it.
This thread, discussing Shark for Root app, refers to a lot of functions that firesheep uses: http://forum.xda-developers.com/showthread.php?t=725692
Perhaps using libpcap/tcpdump (as janfsd suggested), we can port this over. Root is a must though, true...
any updates?
i need this for my N1
Tanks
Bumping for an update on this project!
Found this thread in google. Try http://faceniff.ponury.net/ I've wrote it yesterday I wrote it to sniff only facebook accounts but it can be easily modified to other services.
Hello!!
This is awesome! wooow! I don't mean the fact that you can steal web session profiles,
but the fact that an Android application can open an interface e.g. WIFI and realise sniffing -
network monitoring without being run as root or system. To do so, an application should be
signed with the platform's key : http://stackoverflow.com/questions/6010796/run-secure-api-calls-as-root-android
How is this possible?? I am really wondering about that. Some time ago I tried to port
jNetPcap, so as to use it in an Android application for monitoring the WIFI. I successfully
ported it but I couldn't read the list of Android interfaces from its API and realise web
monitoring.. (see here for details: http://stackoverflow.com/questions/5966603/jnetpcap-on-android-problem-with-findalldevs-method,
http://jnetpcap.com/node/792)
I am really wondering how faceniff faces this problem??
e.g. Shark for Android runs an instance of libpcap in the background and derives the
appropriate information from the pcap traces..
What faceniff do to get the information it wants, e.g. the web sessions?? I am
really curious about that.. Any ideas?
faceniff runs as root....
Yes, but how is it possible to make an application that runs as root?
There is no Android permission you can use in Android manifest to give you
such privileges.. Even other Android applications that run only in rooted phones
cannot open an interface an capture traffic, and for this reason they run in the
background a tcpdump and process the pcap traces it produces (e.g. Shark for
Android).
is anybody here that knows how faceniff can capture packets??
I know how it works because I wrote it
It has a binary file which lies in /data/data/net.ponury.faceniff/
Then the java app executes "su" (to gain root permissions) and executes that binary file. And it grabs results from the binary showing them on the screen. Hope it helps.

[Q] Masters Project question(s)

Hey guys/gals, the folks over at android forums sent me to bug you guys about my endeavor, so if i am annoying, blame them . Also loved the registration video and there were no results of forum posts when it came to robotics.
"Just picked up my new Acer A500 yesterday and have been playing with it just a little bit. It has the unupdated 3.1 OS (honeycomb I THINK). So i have a few questions but first let me explain my purpose for the tab and my background.
My purpose for the tablet is for my Masters project, to interface it to a IOIO (pronounced YOYO) controller board in for motor and senor control. The IOIO is an android driven device hence an android tab. Also the tab is going to the the brains and face of a telepressence robot i am building. My background in mobile devices is windows mobile (forget the version) which i did not mod very much and my IPHONE 3GS which i have jailbroken and modded for my amusement. I also have a background in C# and VHDL but not so much in mobile application development (which i suspect should not be too difficult to pick up)
Now on to some questions. I plan to root this just to have root access but is there any other benefit such as an underground app store. My favorite is book access such as stanza. Can i host a web server on the tab or will i have to remote into it using some other utility? And i thought i had another question but i think that will do for now. Anyways thanks for any help and i look forward to future interaction."
SD
Regarding root, some apps need it. For instance, the advanced features of Titanium Backup or AdFree. As for setting a server, I am using File Expert, a file manager with some cool options (including root access) that also allows http and ftp sharing of files to and from the tablet. I am sure there are other apps with similar functionality.

You don't expect anyone to answer that with a link, right? You can install whatever apk you want with or without root on your own risk. The benefits of rooting have nothing to do with stealing of applications. You simply get r/w access to the filesystem.
Sent from my A500 using XDA Premium App
No need for an "underground" app store. You can use the regular Google Market, Amazon App Store, AppBrain, and GetJar to acquire and install applications.
If you are writing one yourself, then merely compile it and package it appropriate for the Android OS and you can install it without a market as long as you enable "Unknown Sources (Allow installation of non-Market applications)".
Thanks, I have never used the android device before so i was not sure of the actual restrictions the OS has as far as modifications compared to the Iphone, which is what i'm use to. If i offended anyone as far as the thinking i'm looking for free apps, i apologize. I'm more interested in direct access to the accelerometer, 6 axis gyroscope, and compass for instant feedback for my robot navigation system, as well as setting up either web server or remote capabilities to motors and functions through the device. It's all about what type of control and feedback i can gain from root versus not rooting. As well as tethering my iphone to it for greater bandwidth range, when WIFI is not available or weak.
Again any info regarding this type of information would be great.

Have a look at the sdk. You don't need root for the things you intend to use your tab for. Root is needed if you need to modify the filesystem and you don't. You aren't helping yourself with thinking in the ios box. Android is much more open and thus much more friendly to the developers. All google apps are created using the same sdk that's available to us all, so if they can do anything, we can do it too (or at least we have the means to do it). There are some good examples in the sdk too, that can really help you to understand the means of reading sensor data. If I remember correctly, you had some C/C++ background, so it might help you to look as the ndk too.
Sent from my A500 using XDA Premium App
Android is much more open that the iOS, if you have a basic linux background, you can apply it here too. Rooting allows you to edit the filesystem, the equivalent of being able to write to the c:\windows and c:\program files folders. Occasionally, you may need it, but for most applications, you don't. The SDK is pretty powerful and its tutorials are quite comprehensive, with a little studying, you should be able to write an app that extracts the information you want. In general, Android app development is quite open and flexible.
As for the underground app store, there are many free apps in Google Market. Angry Birds and AdFree for instance (this is just to show that not just second rate developers offer free apps). Also, Amazon has a marketplace and they occasionally have offers for free or very discounted apps. In general, if you need an app, there is probably a free version that is supported by ads, or a lite version you can try before buying the full thing.
Just buy the Iconia tablet already.Erica promises you will love it..

ExtensibilityApp class in WP 8.1 Silverlight

Hi all,
If you've read the text that USED to exist here before, scratch that. Big Thanks to @Sunius1 for clarifying what I thought was a win. Due to this, I DID find something interesting in regards to the ExtensibilityApp class (Windows.Phone.System.LockscreenExtensibility.ExtensibilityApp). I happened to also find a hidden capability "ID_CAP_SHELL_DEVICE_LOCK_UI_API" (Seems to be a locked CAP because it only works on Emulator. I get a deployment error on my if I try including this capability). I suspected that these two worked together, but I wanted to make sure of this.
Before we get started, read through the documentation from this site: http://msdn.microsoft.com/en-us/lib...lockscreenextensibility.extensibilityapp.aspx.
We have the following methods:
BeginUnlock
EndUnlock
GetLockPinpadHeight
IsLockScreenApplicationRegistered
IsSystemOverlayApplicationRegistered
RaiseToastNotifications
RegisterLockScreenApplication
RegisterSystemOverlayApplication
UnregisterLockScreenApplication
UnregisterSystemOverlayApplication
EDIT: After the release of the Live Lock Screen app, my speculations about the ID_SHELL_CAP_DEVICE_UI_API capability and the ExtensibilityApp object were correct. Thanks to @jessenic for finding out a good bit of info on this with me.
It seems that in order to get this working, we have to add an Extension to the WMAppManifest.xml
<Extension ExtensionName="LockScreen_Application" ConsumerID="XXXXX" TaskID="_default" ExtraFile="Extensions\\LockAppExtension.xml" />
In the LockAppExtension.xml:
<?xml version="1.0"?>
<x:Extension xmlns:x="urn:LockApp">
<AppID>AppNameForLockScreen</AppID>
</x:Extension>
As usual, Microsoft doesn't really give us much in terms of documentation.. Probably because it isn't meant to be used by the normal developer Confirmed: For now we have to actually ask for permission in order to use the cap. As to whether we'll get that granted? Who knows....
All of these methods have no parameters at all, but I can almost guarantee this has to do with having an application that can control the lock screen.
This thread will be for efforts in breaking this open and seeing whether we can create lockscreen applications..
Homebrew Lockscreen Apps:
Lockscreen App by @-W_O_L_F-
There are actually two Windows.winmd files in Windows Phone SDK, one for Silverlight 8.1 apps and one for Jupiter 8.1 phone apps (located in C:\Program Files (x86)\Windows Phone Silverlight Kits\8.1\ and C:\Program Files (x86)\Windows Phone Kits\8.1\). There's only one the phone. And some APIs support only one app type (it's phone limitation it seems: faking .winmd file results in Platform::InvalidOperationException, saying you cannot use that API from this app type). That explains why the one on the phone has more APIs available than either of for single app type.
As for LockscreenExtensibility - it's documented, just not available for Jupiter apps:

Well that is very good to know! Thanks for the clarification. The best part is that I was actually able to compile without receiving an error (somehow).
I found something that may be of use in order to get the LockscreenExtensibility working (I just tried on a Silverlight 8.1 app and got access denied).
<Capability Name= "ID_CAP_SHELL_DEVICE_LOCK_UI_API"/> <----. Can't be used OOTB
EDIT: I just tested this in the Emulator and it really IS the capability that the LockscreenExtensibility needs in order for it to work.

I speculate that this is what he's using. I bet there's more going on that we have yet to figure out. It also could be that the base class EXISTS, but the full implementation isn't available yet. Who knows.

Ah, Yes that makes sense. I wonder if there are any other "half-baked" API's in the SDK?
Edit: I Know it sounds stupid but honestly I think we should have a thread dedicated to finding odd API's (Just found one: Windows.Phone.System.SystemProtection, nothing terribly useful though)

there are also some hidden APIs in the current SDK for 3D Touch-enabled Apps!
From WP Central:
Some of the features include APIs for gestures, side interactions and even heat maps.
Crazy stuff.
Believe it or not, some of these APIs for developers are in the current SDK, they're just not visible. What this mean though is developers will have access to this 3D Touch technology for their apps. It also means that Microsoft will have a small batch of third-party apps supporting this 3D Touch technology on launch day.

Yea, even though those 3D touch APIs may be available, they're not particularly useful, as they require special hardware to work.

That is true. Sort of of a side question though, has anyone made a OEM account and looked over the API documentation there? There maybe some useful things we could learn about WP and maybe further a jailbreak for all WP devices....

something to force the volume/music control on the lock screen to automatically open would be really useful as well
Updated first post with some more data since the Live Lockscreen App debuted yesterday. There's more I didn't get into, but I want others to dig in and find out
I suppose we can only speculate how it works at this point, but if I had to guess, it goes like this:
1. You have 2 projects in your LockScreenApp solution, one for the application to register the lockscreen, and the second one for the actual lock screen application.
2. The former would use ExtensibilityApp APIs to register the the second one, coupled with the manifests so it's all "valid".
3. The second application is just a another app that is able to process input and draw whatever it wants on the screen. That would explain why there's a delay at it starting when you press lock screen button while the phone is sleeping (probably it's a time for .NET to startup? Direct3D app should be able to start much faster).
Although this is only speculation, I think this makes sense, because that's how background tasks work on Windows, at least. I wonder though, why Microsoft is not releasing the APIs to be used in public - are they afraid somebody will make a lockscreen application that will drain the battery fast or something?

I don't think its that but most likely the fact that the API is un-optimized, some of the facts you stated (i.e. Slow start up, documentation is lacking) etc... The fact the OS needs to be updated to show a section telling the user what lock screen app has taken over (since the setting page doesn't now)
Edit: Remember what Joe said about keeping the lockscreen in memory and 512MB devices might not be supported for that reason? Yeah seems like they aren't doing that since you can see the resume time for the lo screen is wayyy to much

You are correct. Two projects: One is the settings page, which is the main entrypoint of the app when it's opened from the start menu and the second one is the actual lockscreen app.
The settings page uses the ExtensibilityApp APIs to register the second one as a lock screen application. That second application is another 8.1 Silverlight app that uses a LockScreen_Bridge WinRT component that has native access to read what is shown on the lockscreen from the WP Settings item.
It then uses some storyboards to make it do different things as you're swiping up and down on the LayoutRoot grid. It does use a timer so that's where that little lag comes from.
The only background stuff it's doing is latching on to system events ("Start button being touched for example").
I can see where MS would be protective of this. They DID say that they would be releasing a public version of the API at some point. I'm hoping it's not one of the situations that leaves it public only when they've approved you to be able to use it.
It does suck that it's restricted to 8.1 Silverlight though. I could see some Music Apps wanting to take advantage of the lockscreen like this.

Need help developing a lockscreen android

Hey guys, I plan on creating an app but I need some tips and/or tricks to help me get started. I do plan on releasing the app on here (Using XDADevelopers) first to get some attention, then release it on the Google Play store. Here are the details of the app:
App Type: Lockscreen Customization
Minimal SDK: API 16 (JellyBean)*
Testing Device: Samsung S6 Edge (Rooted, running Android Marshmallow)
IDE: Android Studio
Key Components:
The app must be able to detect weither the home button is being pressed (which makes the phone access to the launcher, we dont want that) and quickly intercept the action and return back to the locker
Allow to lots, and I mean LOTS of customability (Much like C Locker, which is the app that has inspired me ^^), some of these customizations include the following:
App widgets and custom widgets like images, text, sprites, etc
LED/Vibration/Notifcation settings for apps
Change speed of animations (Like NovaLauncher does), also be able to choose different types of animations for the lockscreen
Customize colors in app
Integrate Android Wear (make the watch vibrate or ring your phone is low on power, or when the connection is lost)
Different lockscreens that show whenever the conditions configured are met, similar to C Locker (like bluetooth connections, music playing, WiFi, SmartLock conditions ,etc)
This is the cricual part: MUST have several different unlock unlock, like fingerprint (Thanks to Android 6.0.1), pattern, pin, SmartLock, Slide-To-Unlock, and Gestures
Be able to integrate as a plugin for Tasker, like have tasker check for launched apps
Intregrate voice assistants like Google Now/Google Assistant, S Voice, and such others
Have high and steady performance for all phones like. Also not be a resource hog!
This may is maybe feature: Be able to do functions like override the system settings and bypass system lock via root
Utilize Material style (this is a personal preference tbh)
I will add in some more ideas I have for the app.. Actually, I haven't gotten a good name for the app, but I'm thinking of Trinity Locker.
As you can see, I have numerous of ideas for this app.. all I need is some help with creating it. I will warn you guys this, I am pretty new to Android development (I typically code on Minecraft, even created some pretty decent mods), so I need some guidance on what and how things work with the Android system. I do have some coding experience from coding mods for Minecraft and taking a class on the basics of C++. If you guys have some ideas or tips and tricks to give, I'm all ears. Thank you!
NOTE: Anything with a * means that it is subject to change!
Oh yeah, I forgot to mention, I did also have a chance of using MIT App Inventor so I have a small foundation of the Android development. But I am new to Android Studio, so I need some tips with using that as well.
ALSO, to crucially note, I am in high school.. So I may not have time to respond to everyone/program the app since I have majority of my classes are cross college (or to most known as Dual Enrollment or Advanced Placement (AP)) courses :crying:. Oh and I live in the Central US Timezone, so my time will be different (or the same) for most

This may is maybe feature: Be able to do functions like override the system settings and bypass system lock via root
Utilize Material style (this is a personal preference tbh)
I will add in some more ideas I have for the app.. Actually, I haven't gotten a good name for the app, but I'm thinking of Trinity Locker.
As you can see, I have numerous of ideas for this app.. all I need is some help with creating it. I will warn you guys this, I am pretty new to Android development (I typically code on Minecraft, even created some pretty decent mods), so I need some guidance on what and how things work with the Android system. I do have some coding experience from coding mods for Minecraft and taking a class on the basics of C++. If you guys have some ideas or tips and tricks to give, I'm all ears. Thank you!

What I meant by the recommended api is the api I'm starting on first (since that's what Android Studio defaultly sets mento the develop on the latest first)
Hey I have gotten the first bits of the app started! I'm trying to work on the setup phase of the app (where the app asks for permissions and basic settings to start). I even got the code uploaded on Github. Oh also, I might create a XDA Developer project and start adding some info there
Hey guys! I've been adding lots of stuff to the app! If you guys notice something off with the coding, please let me now at Github! Thanks!
