Compiling Emulators (with native code) - Android Software Development

I was looking on google code and found this: code -dot- google -dot- com/p/androidgens/ And by extension this: sourceforge -dot- net/projects/androidemu/ (sorry the links aren't clickable, understandably, that's forbidden from new users. ). And so I went to download them. The svn repository in the first link runs, but does nothing (I started looking at logcat, and got missing library exceptions), the one in the second link wouldn't even compile. I than noticed that the project had native code which I probably needed to compile. So I downloaded the android-ndk-r4b, and started reading the documentation. It seemed simple enough, just cd into the project directory, and run it (or use some other flags if the native code isn't in the jni folder). Unfortunately, the code didn't compile, they first thing it did was complain about missing libraries: utils/Log.h and nativehelper/jni.h, here is the full output:
(Output redacted in an attempt to get this post posted)
So I first thought that my computer must be missing some dependencies...and than I realized that that was probably a stupid idea, because unless the android-ndk statically links your computer's dependencies into the generated library, it wouldn't actually work. So I realized utils/Log.h and nativehelper/jni.h probably should be in the ndk (or linked to it at least) itself. I preformed a query, and it seemed like it was. So I'm out of idea...can anyone help me compile this code (or at least figure out what this specific issue is?) Thank you.
Also, if this is an inappropriate place to ask this, I apologize, and am willing to ask it somewhere else if needed. (And sorry if this is a dumb question...I'm still a bit new to the ndk (a know a bit more about the sdk though...)
Again, thank you.

building a kernel with device driver

Hi,
I am new to the android development and a bit confused from all this (root, no root etc).
Say I want to write a new kernel driver to handle keyboard input, and want it to run only on my phone. And my phone is not the developer phone, nor exploitable for root privilege escalation.
Can I download the source files and compile a new kernel with my driver? I guess I cannot use the Android sources, but need my phone specific branch. e.g if I own an HTC Hero I need to get the specific sources from HTC, and they don't publish kernel sources for all their models...
But if I found the source, add my sources and compiled it, It should be easy (and legit ) to load the new image to the consumer phone right ?
Thanks
Roee
More or less that is correct. The source code will contain the license terms, if it says GPL then you are golden. If you get the source from a questionable route and it's not necessarily "public" then it goes into a gray area. Generically speaking, if you get the Android source, and the source code for your keyboard, build an image with it, flash it to your phone, then you are perfectly fine. If you choose to redistribute that code that you mashed together, it's arguable you'd then also have to publish your mashed up code or at the very least the 2 sources you used to mash it together. Mash is the best word I can think of right now
-Chad
Thanks for the reply Chad.
If the software is GPL, and I don't intend to publish the code, I just want to play and check couple of things.
I wonder if i can only compile a new keyboard driver (for example), and just load the ko file somehow without flushing the whole kernel.
I don't have much experience in the linux world, but I would guess it will be something like :
get the branch from the android git
compile a new kernel object for the keyboard
use adb to load the ko file to the device
insmod the new device
somehow remove the current keyboard device and map a new device with the new kernel driver
is this the correct flow ? is there example of how to do it somewhere ?
Cheers
Roee
Ok, I think I have a little better understanding after I played with my G1 today...
So now I understand how to enumerate all the devices in the system, and find the proper devices (e.g using cat /proc/bus/input/devices , or in /devices/virtual/input/ ), but I fail to understand how to replace the proper lkm module. When I run lsmod, the only module loaded is the Wlan module.
How can I find which file is responsible for the keyboard and replace it with my driver? Or must I recompile the whole kernel in order to replace the driver with my modified driver?
I guess it became an easy linux questions.... (just not easy for me )

Run a Java applet on HD2?

Is there anyway to get the Oanda FXTrade platform to run on the HD2? The only solution I've been able to come up with is remote desktop, but that is far from optimal. This link: http // www smartphonemag com/cms/blog/9/how-do-i-run-well-known-oandacom-stocks-applet-my-pocket-pc-incl-tons-brand-new-never-publish (had to edit out the "."'s and replace them with spaces to get around the spam filter) talks about running it on WM, but the link to the .jar file is bad (and I had tried it before on my Tilt when the link did work, but never could figure out how to get it to work).
Here is link to the Java Web Start that I normally run from my PC: https //fx1 oanda com/java/beta jnlp (again "."'s replaced with spaces).
Has anyone had any luck at finding a way to run Java programs on the HD2/other WM devices? The 800x480 screen and 1GHz CPU would be perfect for mobile trading. I would be so grateful if anybody has any suggestions.
yup man..been waitin the same... pls help..
Same here, if anyone finds a solution I will be really interested to know!!
For now, I'm using Metatrader for the same purpose...
Yes, this is needed so much. I have different websites that need java applets for my hd2. Is there a solutuion today?
I think the Oanda FXTrade platform has changed since he wrote this article.
even this page: http://www.winmobiletech.com/sekalaiset/OandaComAppletInvoke.html
that he wrote to access the oanda platform is failling due to http 404 (file not found) edit: not the page itself but the page trys to request the platform.class file for the beta.jar and it returns a http connection failed to the java console.
I have looked into this quite fully.
It seems the stuff he was referring to was all beta code and has now been removed.
I have found the current jnlp file:
http://fxtrade.oanda.com/fxgui/desktop/fxtrade.jnlp
The new codebase seems like it should be:
https://fxtrade.oanda.com/fxgui/www/fxtrade
and there are now three jar files instead of one:
https://fxtrade.oanda.com/fxgui/www/fxtrade/trading-app.1.10.17.jar
https://fxtrade.oanda.com/fxgui/www/fxtrade/trading-res.1.10.17.jar
https://fxtrade.oanda.com/fxgui/www/fxtrade/protobuf-java-2.1.0.jar
I have tried to modify what he has done in the tutorial you posted to add the new information.
Unfortunately this has been unsuccessful and I am unsure where to go from here.
maybe someone who knows a bit more about jar/jnlp architecture could take it from here?
download the applet, then go to start > tools > jblend
there should be a list of applets.

Wanted: Compile for Android ON THE DEVICE!

Way back when, I could run a c# compiler on my Windows Mobile phone and create apps. I think it would be fun to do on-device "compilation" on my Desire Z too.
I'm not asking for an IDE -- just something that can take Java source code and XML files, compile to bytecode for Dalvik and produce an .apk -- all on the device itself.
Is this possible?
OK -- we'd have to both a javac (java compiler) and a dx tool running on the device to do this. The first compiles the java source, the second takes that file and converts it to Dalvik bytecode.
Anyone else interested in this?
I'm very interested too. I tried sl4a but it's limited for now.

Dexify java compiler
I'm also very interested!
I develop in Java for the Eve VM on Windows Mobile: [www t-arn com/software.htm]
but for this I needed to install a JavaVM on the device.
But it should be possible to dexify the java compiler. I found following post:
[www ist-music eu/developer-zone/documentation/phoneme-and-osgi/music-on-android]
The porting of OSGi requires the dexification of the OSGi bundles. This is a process which makes any JAR file (compliant with Java VM) compatible with Dalvik VM. It basically consists on adding a new file, classes.dex, into the JAR file. To dexify each OSGi bundle, a two-step process is required by using the Android SDK tools. In windows, the process would be:
* Create the classes.dex file associated to the JAR file:
[ANDROID_SDK]\platforms\android-1.5\tools\dx.bat --dex --output=%CD%\classes.dex my_bundle.jar
* Incorporate the classes.dex file into the JAR file:
[ANDROID_SDK]\platforms\android-1.5\tools\aapt.exe add my_bundle.jar classes.dex
Now, the dexified bundles work on both VMs: Java VM and Dalvik VM.

I guess, we could do that for javac. If this does not work, we could try another Java compiler:
- EJC: [thecoderlounge blogspot com/2010/05/ecj-eclipse-java-compiler.html]
- kopisusu: [klomp org/KopiSusu/download.html]
I have no idea how to dexify the dx tool, though :-((
Hope to hear more from you guys
Tom
I have not yet gotten the Android SDK (nor a device...) but it seems that the dx tool itself is written in java. There is a dx.jar in the SKD. This one might already be dexified...or we could dexify with itself.

On-device development & compiler on a server...
Hi guys, I'm new to this Forum - just got my Archos 101 and now I'm searching for some more fun with it ;-)
So I really liked you guy's idea of having a compiler on the device itself - especially since the java compiler's really fast, so no doubt it can run on a smartphone...
I was really tempted by the open source "Open Blocks" library (education.mit.edu/openblocks) from some of these "Lifelong Kindergarden" people at the MIT... they're having this neat programming environment for teaching children programming, where you can drag/drop your source code like Lego...
Here you can have a look how the programming looks:
education.mit.edu/webdav/How%20to%20Create%20a%20Procedure/How_to_Create_a_Procedure.html
Now even google is using a similar thing, probably the same sources for their "App Inventor" (appinventor.googlelabs.com/about/), but you can only develop online at a real pc, then the .apk file is packaged on the server and downloaded to your android device...
So that's practically another way of having stuff compiled "on your device" - you could do the the development on a device and then have a server dedicated for a fast compiler and dx run...
Basically, I'd say that's the perfect system to write quick programs on a touchscreen device, especially when it's a bit larger tablet...
So if anyone wants to join in, I think I'm really keen on trying to port this OpenBlocks thing to the android screen ;-)
Cheers,

Java IDE on Android
Hello everybody
I have just finished the latest version of taJavaIDE (0.3.0)
This APK is meant to become an Android development tool with which you can create native Android apps (APKs) ON the Android device itself.
What is working so far (on my Desire HD):
- Eclipse compiler for Java is integrated and working
- dx tool is integrated (not yet tested properly)
- BeanShell Interpreter is integrated and working.
You can write your own BeanShell script, store it on your SDCard and automate
the build process with it.
What is NOT yet working:
- aapt
- apkbuilder
- jarsigner
- zipalign
apkbuilder and jarsigner should not be a problem. I think, I can integrate those in the same way I integrated ecj.
As far as I know, zipalign is not absolutely needed (I might be wrong here, though).
My biggest problem is aapt which is not a Java application but a C++ application. To make it run on Android, you would need to port it to Java (looks like a REAL challenge!) or use the NDK to create a native library that you could then access from the APK.
I have no experience with the NDK and I also don't have the necessary build environment, so I would really appreciate if someone would help me out here!
Anybody interested in contributing?
Tom
Wow, thanks for getting this started, t-arn!
It's been forever since I did any C++, but I'll take a look at aapt and see what I can figure out.
Hopefully, a true C++ programmer will come along and set us straight
I'm very interested in this project and I would be willing to try to help out if you need it. I'm a second year software engineering student and I'm currently on a work term where all of my work is with android. I may not be of much help but at least I think I have some idea what I'm doing so let me know.
you are correct in saying that zipalign is not necessary. we only need it if we want to sign the apk in release mode(for publishing it to the market). We could just use debug mode and everything would be fine. I'm sure that if someone wanted to release an apk to the market, they could just copy the files over to their pc and zipalign it there. We would still be able to use the apk on the device without using zipalign.

- jarsigner

Serison has an application on the market to sign APK's. Just thought I would let you know it is possible.
I would like this as well, as my phone has a physical keyboard and typing code isn't that bad on it - atleast not for minor edits/tweaks

Sounds possible, if you have the right components. I would love this. Would definitely donate to whoever got it working easily and 100%.
Very interesting project
Look nice. Downloading now.
I have wanted this since I first got an android phone.
I ended up using a virtual debain command line running OpenJava to compile and run the stuff. But if i can do it without that hastle in one app, I will LOVE you.
Edit: I tried it out. Mind explaining how to make a beanShell script? on the ECJ it always gives me a security exception even with just -help.

Please join the JavaIDEdroid support group at http://groups.google.com/group/java-ide-droid and re-post your question there.
I'd like to keep discussions there.
Thanks
Tom
very interesting, ill join the group, i can make the native lib for the aapt.
I would say get gcc working on the device then you can compile anything. You can compile a javavm. A native binary. Etc. If gcc can be compiled and work then all programs most likely can be compiled on the device assuming the proper libs are there to compile against.

tldr?​
Derp is a general-purpose, platform-independent installer, written in python with wxpython, that executes .derp XML-based scripts to walk the user step-by-step through a ROM installation (or do whatever you want.) The idea is to replace text-based walkthroughs, howtos, and installation instructions by requiring a user to do almost nothing but run a .derp script and sit back. Derp walks through a series of scripted steps (as in, say, a ROM installation) and automatically does all the file downloading/adb/fastboot stuff while the user waits and maybe reads what's happening (at the script author's discretion). Derp also pre-installs and keeps Google's Android SDK tools up to date and even gives adb & fastboot a simple UI. .derp scripts are human-readable XML. Embedding bash and python is also supported in Derp, as is restricting scripts or even script parts to certain platforms. Derp runs as root on the local computer (it's an installer after all), and is open source/GPLv3 licensed. It also comes with sample scripts and a built-in tutorial for creating your own.
Still tldr? It's a script-runner thing!
-----
LONGER DISCUSSION...​
WARNING: RIGHT NOW, DEVELOPER TYPES ONLY! This is not for end users...yet. Hopefully people will find bugs and help fix them before an end user uses this on a “live” computer with an actual device. Again, because this is a software installer, DERP AND ITS SCRIPTS RUNS AS ROOT. Never run random .derp or .xml scripts you find on the Internet. This could screw up your device AND your computer, so... treat it just like any other script you’d (not) run as root. Also, the discussion in this forum is how Derp is supposed to work, but of course, there may be (probably are?) bugs.
THE "PROBLEM" AS I SEE IT
Working on the CM wiki, I've grown to appreciate how varied firmware install methods can be. Some devices need rooting. Some need firmware downgrades. Sometimes you can use fastboot. Other times you can’t. Some systems need to unlock the bootloader, etc. etc.
Installing this stuff can be hard. Okay, maybe not for you, but how about your mom or dad? Could your grandparents buy a device today and put CM on it themselves? There's been some chatter on the interwebs about how to make rooting and replacing firmwares easier... some kind of graphical installer seems to be the answer. But there are a million devices out there...
So people have been using text-based HOWTOs, walkthroughs, step-by-step instructions, and/or shell scripts and batch-type files to do this. I thought maybe a generic, unified scripting method might work better that gives the users readable instructions but optionally automatically does technical steps for them.
Hoping to avoid creating yet-another-standard-way-to-do-something, back in February, I searched online for generic installation solutions. But they all seemed to be platform-dependent, or weren’t licensed for general use, or looked really ridiculously complicated....
So (and big caveat here-- I'm not a programmer!) I whipped up a proof-of-concept for developers to play with to start thinking about how to address the issue. It took me a few weeks to get going, but ended up sitting collecting dust for months as I worked on other things and occasionally bothered friends to test the latest version.
Derp is not necessarily intended as any kind of final solution per se-- it’s just for further discussion/testing. A totally legit question to be answered: is this in any way even a good idea?
Let's find out.
SO WHAT IS DERP?
It's a general-purpose installer, written in python with wxpython, that executes .derp XML-based scripts to walk the user step-by-step through a ROM installation, optionally doing all the "technical stuff" like downloading files and running commands in the background. Ideally, you wouldn't have to write a long tutorial for every platform on how to do stuff-- a .derp script could BE the walkthrough.
The first thing Derp does is install the latest adb and fastboot from Google. That looks like this:
(Mac version)
Next, when you run a .derp script, it can automatically download and verify ROM files like CyanogenMod or tools or whatever from the Internet, and then install them.
(Linux version)
(Mac version)
As it does all this, the script can provides information and/or feedback to the user via a UI that hopefully looks like a normal installer. What the user sees is written by the script author in simple HTML. As the .derp script runs, the user simply ftaps "Continue" to proceed through the scripted steps.
As mentioned, .derp scripts are written in XML, which is platform-generic and easy for a human to read. The .derp script syntax, explained below, is also very simple. The script author is also free to embed bash shell scripts or python (or both) if advanced stuff is needed.
Worth mentioning too-- sections, steps, text, actions, or entire scripts can be restricted by the type of computer its running on (ie, don't run certain python commands on Mac, but do run them in Linux, or whatever).
And finally-- while my initial thought was to use this for installations of ROMS like CyanogenMod to a device, I'd think Derp can be used for many kind of installations or scripted operations-- even to wrap a UI around a bash or python script to make it easier for users to run without having to open a Terminal and start typing. Derp scripts don't even have to have to be used for anything to do with mobile devices, though it does pre-set up the Google SDK tools for that purpose.
In fact, a Derp script can do NO actions-- simply serve as a click-through set of HTML-based instructional steps for a user to follow by hand. Conversely, it can say nothing to the user but "Stand by, doing everything." and that's it.
FEATURES:
Easy to install. Debian-based Linux just uses sudo dpkg -i derp_0.001-1_all.deb and it's ready to go. Mac users: it’s Derp.app. Done and done.
Derp is GPLv3-licensed and source code is available now. Read license for terms, conditions, and more disclaimers.
Automatically downloads/updates all SDK tools (primarily adb and fastboot) directly from Google at every launch. So the user is always up to date. (also requires users to agree to Google's T&C...)
Uses an XML-based, OS-neutral installation script format that is easy to write and understand. Just about anything you want the user to do-- restart in bootloader mode, unlock the device, etc-- the derp script should be able to do. Even run bash or python scripts from within the script.
XML Tags:
<derp> - the main tag for a derp script.
<section> - a major category for individual steps.
<step> - Put as many of these in a section as you want.
<info> - The stuff the user sees as the script runs. You can add HTML tags to make it look good.
<file> - tell derp a file’s URL, MD5/SHA hash, and local filename. Derp will grab it and verify it for you automatically. These files can be roms, scripts, recovery images, etc. whatever your script needs to do its job.
<action> - valid “action” types include “adb”, “fastboot”, “python”, and “bash”. Future versions of Derp can add more. <action> allows your script to do stuff. Never worry about whether the user installed and set up the latest versions of adb or fastboot properly. They should "just work".
Using the above tags, you can not only have your scripts automatically do full installations, rooting, bootloader unlocks, etc, but simultaneously tell the user what’s happening behind the scenes if you choose. The user feedback is written in standard HTML-formatted text. The user just hits “Continue” whenever you want to move from one step to the next.
Included are example scripts to install CyanogenMod 10.1.2 on stock Nexus 7, Nexus 4, Galaxy Nexus, and HTC One. The latter script, written by Cowmix, demonstrates how to embed python to interact with the user, and they all include bootloader unlocking.
The only things I can think of that can’t be done automatically are steps that requires hands-on (ie, holding down buttons during power-on) or where, say, debugging mode needs to be manually turned on, or the slider needs to be physically unlocked. In the few cases where user involvement can’t be avoided, the <info> tag can be used to walk them in “real time” through that step.
A built-in tutorial on how to write your own .derp scripts explain how the tags work. (The tutorial itself is a .derp script.)
A console window helps you see what derp is doing in real-time...
Also included: a quick-access adb and fastboot text-entry in the console. This lets you start up Derp and type quick adb or fastboot commands without needing a terminal (or to deal with PATH issues)
“Debug Mode” lets you go through the script without invoking the <action> tags. Makes writing scripts easy.
Derp should automatically detect when a device is connected via adb or fastboot and let you know.
You may filter any Derp tag (including <action> tags) by operating system. This means that using a single script, the user can see different text or the script may behave differently depending on the platform. In fact, you can restrict the entire script to a particular operating system(s).
The script doesn’t actually have to “do” anything. It can be used simply to create walkthroughs or tutorials in a much nicer format than a step-by-step text file. Just link to a .derp file and let it walk the user through whatever. Easy to convert a text walkthrough to an interactive click-through just by adding <section> and <step> tags.
WHY MUST DERP RUN AS ROOT?
Remember, Derp is an installer. It needs to do important stuff, and as such it runs as root. I had considered trying to sandbox the parts that "needed" root and only enable it there and ask for permission for a single operation via an "enter your password" type of dialog box. But because the .derp format is so flexible, there were a million potential places where a script author could do varying kinds of trickery-- by breaking out of Derp to execute python code, spoofing directory paths, abusing the embeddable bash scripts, etc. It just didn't seem to make sense to try to anticipate and counteract all that. Playing cat-and-mouse endlessly is pointless. Again, Derp is an installer. Installers get administration permissions. Just like any installation script you'd run with "sudo" would get. Just like the package installer on OS X. Also, it is much easier to run adb and fastboot with root permission-- you can easily kill all running versions of adb for example, and fastboot seems to prefer it. Plus, it avoids the need for playing with udev configuration stuff in Linux.
This means that, like pretty much every other type of installer, .derp scripts will have full access not only to your mobile device, but to the computer Derp is running on. This seems to make the most sense to me, but I invite others to chime in on improving the design if you disagree.
All caveats and considerations apply. Do not run untrusted scripts, and do not run Derp on a "sensitive" computer (however you wish to define that).
WHAT IS MEANT BY "CROSS-PLATFORM"? (IN OTHER WORDS, WHERE'S THE WINDOWS VERSION?!)
I don't have/use Windows. Right now, Mac & Linux builds are currently available. Derp still needs to be ported to Windows, but since it’s wxpython, and I tried to make as little dependent on the underlying operating system, 95% of the work is hopefully done. Anyone with Windows who’d like to help, let me know.
I think it should be some minor changes to the setup.py file and a few definitions. Also, not sure if Windows supports the “bash” shell...
ANYTHING ELSE?
Ummm... That’s it. Remember, this is a work in progress and a proof of concept... Again, I dunno if anyone will see the value here, and maybe it will need a complete rethink. There are likely to be bugs, maybe even really bad ones. But after a few months of playing around, I kinda feel it’s ready for other developers to at least see and even try in a secure environment (as suggested, maybe a VM or something).
SHOW ME THE CODE!
The code is on github-- please submit commits-- fixes, new features, whatever-- as well as bug reports there. And again, figure there will be tons of bugs to be squashed.
Enjoy.

Script Syntax (Tutorial)
SCRIPT SYNTAX​
So you want to write a Derp installation script? It's easier than you might think. Derp isn't too complicated-- it doesn't have a lot of "logic". It just follows a script and does what you tell it.
To start a script file, just get out any text editor (or XML editor) and name it something with the .derp file extension, such as:
sample.derp
Once you write up a sample script, you can load the file with Derp to see if it works.
The <derp> tag
Every script starts with the <derp> tag and ends with the </derp> tag. Within the "<derp>" tag, at least for this pre-alpha version, you need to put at least one required attribute, app_version:
<derp app_version="0.001">
</derp>
This is to identify the version of Derp that your script is for. Future versions may not support your script. You can put other attributes that might be used in the future:
<derp device_codename="mako" os="Linux Darwin" title="CM10.1-M1 for Mako" device_name="Nexus 4" device_vendor="lge" app_version="0.001" script_version=".5" author = "fattire" author_email="[email protected]" author_twitter="@fat__tire" license="GPLv2">
These additional tags may be required in future versions of Derp, so if you are able to supply 'em, it's recommended. They'll simply be ignored if they're not needed.
The title="CM10.1-M1 for Mako" is a general title for the script. VERY briefly explain what it does. It's not required, but recommended.
The one other important attribute, os="Linux Darwin", will be explained later. For now, just know that it is optional, but you can use it to restrict the whole script to only run only in certain operating systems.
The <section> tag
Every set of instructions should be divided into logical sections, such as the ones on the left. The section has its own required attribute, the name:
<derp app_version="0.001" os="Linux Darwin" script_version=".5">
<section name="This is the first section"></section>
</derp>
Notice the name attribute is used with a section to identify what the section is for.
There's not much more to say about sections. It's easy. Let's move on.
The <step> tag
Each Section can be made of (at least one but) an unlimited number of individual steps. And the tag for that is called <step>. Here's how it's used:
<derp app_version="0.001" script_version=".5">
<section name="This is the first section">
<step name="This is step one"></step>
<step name="This is step two"></step>
</section>
<section name="This is the second section">
<step name="This is step three"></step>
<step name="This is step four"></step>
</section>
</derp>
Notice that steps, like sections, need to have a designated name attribute so that Derp knows what to display. The step name will appear to the user at the top on the right as the centered step heading.
The <info> tag
The stuff that appears in the main info area should be wrapped in info tags.
Example:
<derp app_version="0.001" script_version=".5">
<section name="This is the first section">
<step name="This is step one">
<info>This is the text you'll see! It explains what's going on to the user. <b>I'm bolding this part because it's really important for the user to see.</b></info>
</step>
</section>
</derp>
Note: The stuff that you put between the <info> and </info> tags is...HTML!
So you can format it however you want. You can even include images from the Internet.
Here is the list of HTML tags that are recognized:
A NAME=[string]
HREF=
TARGET=[target window spec]
ADDRES... can add os="Linux Darwin" to the <derp> tag.

Derp
Derp is a pretty slick interface for scripting not only device installation, but resources needed for modifications on Android devices (namely the Android SDK). A developer can create a custom script to automate the installation, decreasing one off bad installs, and ensuring the process is completed as intended.
People new to Android customization or developers could find this of use. I am excited to see where it goes.

Thanks.. BTW for those asking about the Windows port (in IRC)...
I simply don't have windows, but it was written to be as platform generic as possible. Anyone with a tiny amount of programming skills (again, I have zero myself) should be able to add Windows compatibility pretty quickly... I think it's a matter of just fixing that setup.py file to work with py2exe. See here for more info.

Grats BTW, great idea...
I've come across several usages of Linux only Python functions so far and I don't see drop-in alternatives for Windows, so I've just commented out that particular section (line 1183). I managed to get the tool download working. Suggestion, maybe sticking with MD5 hashes would be simpler as the script receives updates to match Android SDK download updates. I can understand why you would want to use SHA512, but google offers MD5 on the site next the downloads for simple copy/paste replacement. There's the potential for lots of hard-coded configuration and for those configurations to be platform specific, such as the download folders for tool updates. I'll see if I can finish up the first bit of win compat this afternoon, but my Android device is at work and is a Dell Streak at that, so my test options are a bit limited.
http://docs.python.org/2/library/platform.html
1183 - os.geteuid()
1196 - os.uname()

Windows... already?!!
Holy crap! I don't think it's been 12 hours and there's an early windows port.. amazing job!
The unix-only stuff was from a last second addition I did when I realized that dero would try to run on ARM-based linux machines. The easy fix is to simply indent everything past:
if platform.system() == "Linux"
so that the if not os.geteuid() == 0: and testarch = os.uname() stuff is conditional on it running Linux. (Unless there's a windows ARM version, in which case it also won't work).
In both cases it would work except for the fact that Google doesn't provide libraries for ARM. Interestingly though, debian does. So if we REALLY wanted, we could just apt-get install the tools for ARM Linux users. But that would (1) require a debian-based version of Linux, and (2) we wouldn't know that adb/fastboot/etc are the very latest from Google. But it might be a good version .002 feature, with a preference to turn it on or something.
Again, amazing work. Keep it up!

Good deal, glad I could help. If you ever want to give a Mono/GTK# port a try just give me a shout. I could do the majority of the leg work code in C# very quickly, lightweight app, which is excellent these days.
I just pushed up my initial changes for the setup.py. I haven't figured it out yet, there are some imports, specifically in derp.py line 23 (platform) that aren't getting consolidated into the build with py2exe. It's most definitely how I've setup the options in the setup.py, hopefully someone is more familiar with py2exe than I and can provide some insight.

Okay, let me take a second and fix the bug I described above... then-- damn, I wish I could try the setup.py myself. So you're saying that the platform stuff doesn't get imported into the build for some reason?
Standby for the fix.. just gotta test it and stuff.
Update: Pushed. Also added /build, /dist, and one other mac build-related directory to .gitignore to make things a little easier to see...

Question, would doing something like this on line 52 do anything:
options = {'py2exe': {'bundle_files': 1, 'optimize': 2, 'compressed': 1,}},
I think you can also do something like:
includeList=["a list", "of modules", "to include"]
first, and then replace the line above with something like...
options = {'py2exe': {'bundle_files': 1, 'compressed': 1, 'optimize': 2, 'includes': includeList}},
see more info here and let me know if the above gets those modules in there! I see some option called "unbuffered".. dunno if that needs to be set to true.
bundle_files to 1 means that it hopefully will end up being a self-contained .exe
Let me know! Thanks!

Forgot to answer this. You're totally right that MD5 is the one Google provides, and at first I used MD5 for everything-- then sluo reprimanded me, told me how MD5 can't be taken seriously any more, that it's really really easy for anyone to create a MD5 spoofed file these days... So I figured, since this runs as root, it's better to be very extra super-cautious and make absolutely sure the right file is downloaded
Of course, in a user-provided script, you can use md5s or whatever the author wants, but for the Android tools themselves I figured it was better practice to use SHA512 to be more forward/future looking and make sluo (a *real* programmer) happy
More work done by hashcode on a windows port
Okay strvmarv and other windows folk--
Hashcode helped me out by testing on his machine that has Windows.. we did a little debugging, and the result are these two commits:
Pull Request #1
He was able to run derp successfully and do adb/fastboot commands from the Console interface.
But because he's using win64, he couldn't build (apparently only win32 supports building .exe files) all the way.
So, if you have a win32 system-- after applying these, does python setup.py py2exe build an .exe?
Questions:
* on win32 does it build into an .exe?
* If so, does the .exe run properly as the administrator-- right-click and select "Run as Administrator" I am told
* if so, does it install the android tools and ask you to agree to the License?
* if so, does it download/detect your devices?
* if so, can you run scripts (does it work?)
Note: You may also need to manually install Java, since the android sdk updater uses java.
I'm wondering too if the installer installs any drivers, and/or if any were needed.
Thanks!

Awesome, will take a look tonight. It's very likely I'm just not setting the options in the setup.py correctly.
You're running snow leopard, correct? You could grab a copy of the Windows 8.1 Preview (free until Jan something I believe - http://preview.windows.com) and dual-boot, or even just run a VM...if you wanted. I had to install Python 2.7 x86, wxPython x86, python2exe x86, and then run derp.py from source directly (powershell or cmd) to get where I'm at now.

Ideally I'd like to test it on a win32 system because that's the one that py2exe will make a .exe for. But that said, hashcode has it running and adb installs and works and such. It's now a matter of getting it packaged up properly I think. If you can double-check that it works for you, that would be a good start. Then hopefully the .exe can be made. It should also check to make sure java is installed (which is needed by the Google updater) and if not, maybe help the user do it (or even do it for them)...
Also, his version of windows already had drivers on them, so we're not sure whether derp (well, the android tools installer from Google) will take care of that or not.
One last note-- you may have had problems with the looping downloads because the sha512sum seemed to have been off. I did my own sha and it was different.. The new one worked for hashcode.. it's in his commit linked above..
Thanks!

- I'm not win32, I'm running 8.1 x64, but it builds/executes just fine if you're using the 32 bit versions of Python, wxPython, and py2exe due to WOW64, long story

Hmm.. Did you try adding them explicitly in the optionList as I suggested above?
And another way to do it is to use the -p and -i paremeters when you do python setup.py py2exe
Also maybe try adding:
import win32com
after "import py2exe" in setup.py I saw some reference to that somewhere...
What else...
looks like elementc14n is something related to the elementree module of python... win32api is here I think... but I think it would be installed when you installed python to begin with.

For py2exe to work with packages loaded during runtime, the main thing seems to be that u explicitly import the modules needed by your app somewhere in your app. And then give py2exe in setup.py with moudlefinder.AddPackagePath( , ) the hint, where to search for modules it couldn't find by std. introspection. in the app
I won't do a full-on pull to the repo until everything is working and tested against linux/mac just to make sure we're only fixing stuff and not breaking the other platforms in the process

jpath wouldn't pull in for some reason, despite installing via pip and having an import, so I resorted to logic to assign "." as the path (very hacky)...

Ack, storing sdk tools in Program Files\Common Files is great and everything, but it needs to be store in Program Files (x86)\Common Files since it's x86 compiled. Pretty sure things may go wrong at some point as it is...

[Q] Problem getting started on Android Studio

Hey guys,
I have been having trouble getting started developing applications for android. I know how to use Java, and frequently use the netbeans ide for my java homework ect. But I decided why not adventure out and build upon what I learned in school. Unfortunately I have ran into nothing but problems. The first problem is this:
"Gradle project sync failed. Basic functionality (e.g editing, debugging) will not work properly. "
In the messeages window it reads:
[file path to \app\build.gradle]
Failed to Find: com.android.support:appcompact-v7:21+
I have had trouble using grade in eclipse....well I only got eclipse to work once, when I first got my phone, and managed to make a small pop-up app for my self. I did not know any programming language at the time. I merely just copy and pasted most of the code.
and problem number two;
The generated code is riddled with errors?
I look through most of these errors and they state that certain things can be resovled. For example, cant resolve "support" <--- I think that by not having this imported correctly (I think this falls into the first problem) is causing the rest of the errors in my MainActivity file to go crazy.
Is their any way to post more information? Like a log file, maybe that might be of more help too. I just am unfamiliar with Android Studio, as of right now. Attached is a picture of the IDE when is spawns the error.
Thanks for the help in advance!

Ok guys, I figured it out. We need to install a package from the sdk manager. The picture shows which one needs to be installed. The package is "Android Support Repository"
Seems you have already gotten the answer. But for this kind of questions, past the main line of the error log into Google is much faster than post a question, I think.
