Samsung Galaxy Tab Development Environment

Hello developers,
I'm starting this thread because I'm interested in designing a development environment for the Samsung Galaxy Tab so that developers, like myself, can have an easy environment for modifying the Android OS. I'll be aiming this environment at all Android Devices but I want to start with the Samsung Galaxy Tab.
At the moment I don't have much of a structure for this project, nor much direction, so if anyone has any ideas for what tools etc I should include in this please let me know. If anyone wants to get on board with the project it would also be appreciated. Send me an email.
tool ideas:
- integrating the GCC and Javac compilers into the environment.
- integrating a way to generate make files and to build from these files.
- GUI for editing files from the kernel and application framework.
- easy to use way of setting up branches for projects with the Repo and Git included in the Android Source Code.

Count me in. I am getting a Tab tonight and I plan to develop for it. Currently, I have got the froyo source on my machine and want to integrate the open source code that Samsung released for this device.
Has anyone successfully built a custom ROM using the Samsung source code? Any help on this will be appreciated.

Awesome!
I've got Froyo working on the Tab, which I built from the source code from the android open source project website but it's just a generic build from the straight source, nothing special. not with the samsung code though. do you have any links for it?
I've put a small amount of stuff into the Dev Environment, most just shell files etc to make installing everything easier. One click sort of thing.
My first task though is going to be to try and fix the failure that is the Samsung display driver. Most noticeable are the 4 by 1 widgets that don't stretch across the whole screen.
After that I'm going to start work on a GUI for the environment and the iOS Emulator.
thoughts?

Whats wrong with Android SDK and Eclipse?

It's not the most straight forward thing. I'm looking to make something that includes its own libraries too. It's aimed at beginning developers mostly, so you can literally download one file which includes everything you'll need then start editting and then one click to compile and have it all work. Simplicity

I'm also interested in this... The SGT is my first android device, and my company will want android apps for internal and external uses... and a one click dev environment would be a most welcome option!

Straight up AOSP? Could you have a crack at CM?

Anything you need, including testers, I'm in.

I have programmed some programs in android. If you need my help, i will be glad to help,

i'm currently setting up a new galaxy Tab ubuntu 10.10 VM but I always fail at installing java5-jdk, but when im ready i'm going to have a look at the CM and AOSP source and i !try! to port CM to the tab!

I am working on a custom rom , if you need any help do not hesitate

I'll be interested in getting involved in a community driven project for the SGT. I'm a unix admin with lots of experience in the OS and system development field. Interested in what ideas you have on this.

Try using openjdk. It works for me.

Thanks everyone for the positive feedback on all this! it'll be good to have as many people on board as possible.
if you have troubles downloading the sun-java5-jdk there is a good tutorial on it on this site, it doesnt come as part of the repository by default so until you add it in sudo apt-get install sun-java5-jdk will not work.
atm i am only working with AOSP not CM, i am trying to set this dev environment up for a nice simple build and then i'll start working on more complex builds so we can start developing custom roms.
@paulshields - do you know much about linux/android drivers? i wanna fix the widget sizing problem on SGT but my driver knowledge is limited

Porting C/C++ Linux apps via python binding?

First of all let me start off by admitting that I am crazy and a noob programmer so maybe I don't understand the problem and am asking a rediculus question.
I was wondering if there was any way of converting C/C++ source into python that could be run on Android. Mostly command line stuff that would be done over adb or maybe even the terminal. I have got the python interpreter google provides running on the command line, I can access it from adb, terminal IDE, Terminal emulator, it seems everywhere, I moved the files into my /system directorys and add PYTHONHOME and ""PATH to my bashrc and mkshrc files located in the "/system/etc" section and now I can call them from those shells. For instance I can call "bash" and get bash, or/and I can call "python" to get python2.6 ( I have no idea how to implement the "Alternative" method of linking executables like in debian on android so it just has to be thought out, i tested with 2.6)
So with that all being said, if the C/C++ bindins for python ( I don't really even know how those work) were ported to android would we be able to use that to port C source?
And a second question. Does the python interpreter googlecode offers run on top of the Delvik VM?

Sounds pretty complicated and interesting, seen a lot of crazy things happen here over the years so I wouldn't say anything is impossible lol I recommend you ask this in the Q&A section though. Or maybe the Android Development and Hacking section, there's a lot of talented programmers over there as well.

To answer the question you asked: no, that's not a reasonable endeavor.
To answer the one you didn't: it's actually not hard to build most console programs from source to run on Android. You should be able to grab yourself a cross-compiler toolchain, and build the programs yourself. If you're running Linux on your computer, most distros have a tool to build such toolchains, or you can use e.g. MinGW and a Windows toolchain (Linaro might have one) to compile. In general './configure --host arm-linux-androideabi' should set everything up for you.
Obviously, there is a learning curve to building like this, but it's certainly not impossible to do.

Right on, I just started reading the Linux From Scratch book and it has helped me understand the process behind it all a bit, I still need to finish reading the book and build my own Linux system for the my laptop first as that is what they are talking about.
I actually just got msfconsole or Metasploit running on Android, I ran started it up from ADB. I posted another thread about it with more detail.
I am just mounting the filesystems from the kali.img file that I made a few days ago, I basically just did a reverse chroot and brought those directories into Android's "/" directory and then exported the path variables that you normaly would but since I didn't change root and all the apropriate directories where in their proper place it ran.
My next step is to obtain a method for building the Kali Linux for arm system on a ROM, probably a blend of Cyanogenmod and Kali Linux core or rather just the command line programs. I am assuming that once the tools are available to the Android system folks could build gui's that call those programs and return their values and then bundle it in an apk for installation across devices running the modified ROM.
My end goal is basically a version of the Kali Linux distro that runs Android as its "desktop" instead of kde gnome pxe or some of the others. Then hopefully, maybe, if its deemed worthy, a specialized repository can be maintained for this version of the distro that wouldn't include any of the original gui programs for normal Linux Desktops, but only specialized apk's (instead of .deb or .rpm) that install gui's for android.
Thats what I would like to see, a Super Droid.

[Q] Git for jailbroken RT?

Hi everyone,
I use Git for source code management but haven't found a Git client for WinRT. Does anybody know a solution?
Git is open source and can be download from git-scm.com. A pure java version called jgit is available from eclipse.org which I already tried to port using IKVM but without success.
Thanks!

Sadly there isn't one. I can't remember off the top of my head why (and as you can imagine, searching for git on these forums, even in the ported software thread gives alot of results) but there was a reason for why it couldnt be ported right now, probably MinGW or cygwin.
Subversion is available right now as an alternative and thats about it I think.

Cross compilation for armv7

Hello everyone,
I'm searching how to cross compile for armv7 processor such as the one in surface RT or surface 2.
How did the recompiled app found in this section were recompiled ?
I found this github which sounds very promising.
Did anyone used this project ?

To actually compile a desktop program, you need the source code of the program. This means that the program has to be open source (ex: Firefox, OBS, Notepad++, Dosbox etc...). Then, you compile it to the desired platform. You cannot really decompile closed source programs (Photoshop, Chrome...) and recompile it to your desired platform because it's really complicated and you might run into legal issues.
So your best bet would be to compile open source programs.

Yes I know, I'm playing with vlc sources for the moment
When I said recompile I wanted to say compile for armv7.
I just wanted to know what toolchain peopole used until now for the program we can find in this forum

Actually, VLC provides a tutorial on how to compile a build for any platform. They actually use the mingw-w64 toolchain (The same you mentioned on the OP): https://wiki.videolan.org/Category:Building/
They also have a section for Windows 8.1 RT Windows app (It's not the desktop Program) which you can compile with Visual Studio: https://wiki.videolan.org/WinRTCompile/

Yes that's what I'm playing with (cross compile with mingw), but I don't have a lot if time in this epidemic periode...

If you want VLC, don't bother yourself with compiling it, there's a very decent UWP app available on the Microsoft Store and it works for arm 32bits, tho it's a good initiative to start compiling new stuff, I can only encourage you guys to do more, I'm currently trying to see how to compile more cores for RetroArch but it's a hassle, hopefully, pcsx-rearmed can at least be compiled...

LineageOS + VirtualBox?

So i managed to get a virtual android machine running via virtualbox, i used android project x86 for that.
However it contains the typical google-mass-surveillance-spyware, a no go.
How would i get a generic system image (gsi lineage) running in virtualbox?
What more do i need other than the GSI and VirtualBox?

A kernel. GSIs are system only images, so they don't include kernels.

As far as i know, LineageOS doesn't provide Android x86 image. You can use BlissOS instead, they actively develop Android for PC

Thanks! Never heared of bliss. This forum is really great, learning about so many new things here.
May i ask some noobish questions.. bliss has multiple download variations.
GApps (thats google apps...)
FOSS
AOSP
I'f been reading aosp quiet a few times, but foss is enitrely new to me.
Is there a documentation on what they stand for and what the differences are?
If possible i preffer a virtual android device without any trace of google/facebook.

I went for AOSP (not sure what foss is still).
In virtualbox would i choose other linux 64bit or other 64bit ?

FOSS is Free and Open Source software. FOSS build doesn't include Google Play Service in it. Most of users using it for privacy concerns. They only replace Google things with F-Droid. Based on their website they are using Aurora Droid for open-source apps from F-Droid repos, and Aurora Store for accessing the Google Play library of apps

Interesting, privacy is also my nr 1 priority.
AOSP must stand for android open source project, blissos aosp seems to not use any gapps.
What really are the differences from aosp and foss if neither uses google?
