Hi Devs!!!!
I am a Software Engineer and i have a pretty good knowledge of C & Java.
But the problem is that i don't know anything about Linux, how to cook roms or what should be used to open files such as splboot, miniloader...
if any body could help me out with this i think i'd be useful in contributing to the success of our MISSION FREE XPERIA X8...
I need to know exactly how these things work so that i could start with development. Though i get less time in weekdays as I am working but i can definitely work upon these things in weekends and would love to help in any sort possible.
Any kind of explanation, links would be useful..
Thanks!!!
To work with Linux kernel: you need a Linux distro, some development packages, and Linux source
To work with Android source: you may want to start with Android Open Source Project, download the SDK, NDK. There is also instruction to get the source, build, and test. Later, look at the modifications provided by CyanogenMod, or VillianROM, or CodeAurora.
Good luck
Thanks buddy...i hope these links would help me..
hey doixanh!!!
i downloaded jdk, git.tar.gz, python.tar.gz
but i am unable to use it....i was reading the documentation on Android Open Source on how to use it but it doesn't seem to be helpful.
The command that i am trying is ::
repo init -u git://android.git.kernel.org/platform/manifest.git
and m getting the followinig error ::
Traceback (most recent call last):

i am completly new to linux and so i'd be glad if u can help me out in getting started...
awaiting your reply..
Thanks
hey doixanh!!
i am stuck at a point...need your help to go further.
i downloaded the android kitchen yesterday but didn't find much use of it.(plz tell me if i am wrong)
i followed the steps mentioned on the Android Source website and it said to check out the source from git hub using the $ repo sync command.. i did that but it started downloading everything from there which i think we don't require...so now i want to know what all sources do i need to checkout from git hub so that i can work upon those.,,also if you could tell me how to open and modify .ko files(these are the kernel files i guess) i want to have a look into these files and see how things work in our device.
also what other things that i would need, plz let me know so that i can download them...as per now i have python 2.7, JDK 6, android kitchen, and android sdk...Is there any thing else that i would require..
ok Im new to all this Im trying to do the IMEI spoof but cant seem to get baksmali to run right
Im running this on my MBP OSX 10.6.6
I dont know if I have to setup any thing or what but here is what I ran and what I got.
Code:
Java> -jar baksmali.jar framework.jar
Exception in thread "main" java.lang.NoClassDefFoundError: baksmali/jar
Caused by: java.lang.ClassNotFoundException: baksmali.jar

Some help would be awesome.
Thanks
Did you rename your file to baksmali.jar or is it still baksmali-1.2.6.jar?
Ive done it both ways.. but remanded to to make it a little ezer
I have no idea about OSX but I believe for Windows you need the full JDK not just the JRE. On Windows you also need to make sure the JDK folder is in your path.
[UPDATE]
BusyBox 1.19.2
Bash 4.2
Midnight Commander 4.8
TMUX 1.5 - That's right, full terminal multiplexer..
Vim 7.3
Terminal IDE ASCII Soft keyboard first round bug fixes complete.
It's the addition of TMUX and MC that really excites..
--------------------------
Well,
As the only people I know who might even be interested in this, I would like to announce the release of Terminal IDE v1.0.
A complete Java / Android Development Environment that runs on the device itself, with a nice telnetd / sshd feature.
For Android. Of course... Eat this you IPhone Hounds..
Woo HOO!!
The application is available on Android Market.
https://market.android.com/details?id=com.spartacusrex.spartacuside
As what I can only describe as 'dark days' finally draw to an end, I am very pleased with this first draft.
PLEASE give it a go, log in over telnet for a smoother ride, and let me know how it goes..
DO THE TUTORIAL! Does it work ?!
I have released the whole project GPLv2! Yeah, Who Knew!?
http://code.google.com/p/terminal-ide/
BOOOOOM!
Spartacus
a link to the app in the market would be usefull.
Interesting. Was just wondering about coding on my tablet.
Pretty freakin sweet
Thanks for putting this out!
Awesome
The full keyboard alone makes it worth downloading, but the IDE as well - wow!
this is best bro.
I randomly found this last night while looking for a decent mobile IDE for my tablet. I was looking for a simple text editor with syntax highlighting and you've taken that extra step to include other tools for ssh, telnet and compilers. Much appreciated.
One question, how do you start the ssh server? sshd doesn't seem to do it. I would like to scp files to my device from my desktop in order to work on my commute.
Thanks
The sshd app is actually called Dropbear.
You also have Dropbearkey.
You use Dropbearkey to generate the sshd certificates you need.
I really need to add a tutorial on setting the sshd keys up
For now Google has a couple of articles on it.
For file transfers you also have busybox FTP but I admit not terribley secure..
Allthough SSH is provided, and I wonder whether an SSH pipe can be created..?
And lastly you can just copy the files over to your sdcard via USB..
Will look into it & add tutorials asap.
Ok. So I now have SSHD working..
But there is a slight issue.. basically when you log in you have to start bash manually.. unless you have the file /etc/shell with the correct shell to use.. Which requires a rooted phone.
Since Terminal IDE is for non-ROOT users, I will have to recompile the code to allow a shell to be specified on the command line.. Soon..
FOR NOW - This is how to connect to the phone via SSH (There are other ways using public keys but this is one way)
So - Once in Terminal IDE
2) You need to create a couple of server ssh keys
Start in $HOME
Code:
cd ~
Create folder
Code:
mkdir .ssh
Give it some secure permissions
Code:
chmod 700 .ssh
Get in there
Code:
cd .ssh
Now create the keys
Code:
dropbearkey -t dss -f dropbear_dss_host_key
dropbearkey -t rsa -f dropbear_rsa_host_key
ok - That's almost it. Just need to start dropbear with the correct parameters now. [Probably want to keep this in a script]
Back HOME
Code:
cd ~
You need to know the UID of your app, which is different per phone - use 'id'
Code:
id
That will tell you your user ID / Group ID. Let's say its 10058.
Now to start DropBear
Code:
dropbear -A -N username -U 10058 -G 10058 -C password -d ~/.ssh/dropbear_dss_host_key -r ~/.ssh/dropbear_rsa_host_key -F -E -p 8090 -P PidFile
This will start it running in the foreground with password set to 'password' on port 8090.
Then you can connect, like telnet, and simply use 'password' for the password.
Now for the issue. It will start a simple shell session in / with no ENVIRONMENT variables or anything..
I'll fix it permanently in a future release, but for now it can be fixed with these 2 commands.
cd into your home dir - Check this is correct on your device
Code:
cd /data/data/com.spartacusrex.spartacuside/files
And start bash with an init file Terminal IDE auto-magically creates..
Code:
./system/bin/bash --init-file ./.init
Everything should now be setup as usual.
Good luck..
Very awesome and thank you sir. Works like a charm.
One thing to clarify for those "braving" this (not that it's all that insane to try)... the '-N' is setting the username (in the case of the example, setting it to 'username').
Also, it gives a permission denied for scp, I'm assuming since it doesn't init/run the shell. Should be fine since FTP is included. Haven't tried this option yet. Not too worried about security at the moment, since I'll only run it on a private network.
May I make a (maybe) small feature request? Is it possible to include a "keep screen awake" option in the options menu? I have my Xoom config'd to turn off the wifi when the screen is off for power saving (can go ~4 days on 1 charge), so it will kill my connections if I let this happen. I know not everyone has this config set, but it'd be a nice option.
NOW, if I wasn't lazy, I could probably add this myself and build since I've dl'd the source. But, lazy and working on a few projects already.
Again, much thanks.
And as if by magic..
Funnily enough I was having the exact same issue last night while using wget to transfer a big file to my device..
NEW VERSION UPLOADED v1.13
Now has 3 non-exclusive lock types available in the options :
- CPU Lock
- SCREEN Lock
- WIFI Lock
Set them as you wish...
Saw that this morning when I was on the bus (Thursday morning here in Hong Kong). Very awesome and much appreciated.
As well, thanks for open-sourcing it. +1 for you sir!
Very cool stuff
Thanks for creating this.
Great app! However I can't compile .java files. I always get an error that it can't unzip a file in /android.policy.jar. Any idea?
Sent from my GT-I9100 using XDA App
Do you think its possible to also support compiling C sources directly in your phone
I've been searching for this ever since I got an android.
THANK YOU.
Says that it's incompatible with my OG Droid. Any idea why?

Most likely seems to be due to the ROM you are using and/or the market version
can u post the build.prop here?
/system/build.prop
also, try going back to market 2.x, 3.x market(s) do loads of checks
Does anybody know why I can't compile java files? I always get the following error:
Error reading /system/framework/android_policy.jar cannot read zip file.
Any ideas? Could anyone upload there android_policy.jar because that might cause the error.

Hi Schindler33.
Can I ask, have you followed the tutorials, say the first helloworld example TO THE LETTER?
Does the helloworld example work?
The parameters have to be correct, and as always exact, and the BOOTCLASSPATH variable must be set.
If so, is it a custom ROM?
Does that policy jar file exist and is it readable by non root users?
As much info as possible good..
There are a lot of toturials for building CM9 on ubuntu or CM7 on Mac but I couldn't find a decent toturial for building CM9 on Mac (specially Lion). Development in AOSP/CM land is rapid and guides frequently need updating. I had to spend a little time to figure everything out and I decided to share it here.
This tutorial is for building CM9 (ICS) for Galaxy Nexus GSM (maguro) on Mac OS X Lion 10.7.3 using Xcode 4.3 and homebrew . You can easily make the instructions work for most other cm9 devices, but I wouldn't know anything about that.
DISCLAIMER: I'm not responsible if you blow yourself up, blah blah blah
However, I've tried to make this as noob friendly as possible because, well I'm a noob myself
Instrunctions:
UPADTE (MAY 29TH) : The Xcode 4.3 default compiler (llvm-gcc) used to be incompatible with CM9. Thanks to jocelyn and topprospect, the LLVM compatibility patches from mainline AOSP are now merged into CM9. Therefore, you can now use Xcode 4.3 and its command line tools without installing another compiler. However, since GCC is still the only officially supported compiler, incompatibilites with llvm-gcc could still be introduced with future updates. Therefore, if your build fails, it might be worth it to try installing and compiling with GCC 4.2. See the Troubleshooting section for more info.
Now that we have Xcode 4.3 and Xcode command line tools (CLT) installed, let's continue.
Open Terminal and run
Code:
java
if you don't have Java, you will get a prompt asking you to download and install Java. Go ahead and install it.
If you don't have adb and fastboot working, download the android-sdk from google (version r18 as of now) and put it in /usr/local/ and rename the folder to "android-sdk".
Install the homebrew package manager
Code:
/usr/bin/ruby -e "$(/usr/bin/curl -fsSL https://raw.github.com/mxcl/homebrew/master/Library/Contributions/install_homebrew.rb)"
To make sure that homebrew and android-sdk executables are in $PATH:
Code:
touch ~/.bash_profile && echo "PATH=/usr/local/bin:/usr/local/sbin:$PATH:/usr/local/android-sdk/tools:/usr/local/android-sdk/platform-tools" >> ~/.bash_profile
Relaunch Terminal for the change to take effect.
At this point you can run
Code:
brew doctor
to detect any problems there might be (Homebrew may instruct you to use the xcode-select utility to select the xcode installation path). Hopefully, your system is raring to brew
Now we have to install a bunch of packages:
Code:
brew install git coreutils findutils gnu-sed gnupg pngcrush repo
We now need to create a couple of symlinks so that the gnu versions of 'sed' and 'find' are used rather than the osx provided versions :
Code:
ln -s /usr/local/bin/gfind /usr/local/bin/find && ln -s /usr/local/bin/gsed /usr/local/bin/sed && ln -s /usr/local/bin/gstat /usr/local/bin/stat
It's time to create a case sensitive image which will hold our working directory:
Code:
hdiutil create -type SPARSE -fs "Case-sensitive Journaled HFS+" -size 40g -volname "android" -attach ~/Desktop/Android
Now we have a disk image in ~/Desktop/Android. Mount it if it's not mounted already. (Don't be picky about the size, the image will only take as much as space as its contents).
Now we need to create a working directory inside the mounted volume:
Code:
cd /Volumes/android && mkdir cm9 && cd cm9
We can initialize and download the source now:
Code:
repo init -u git://github.com/CyanogenMod/android.git -b ics && repo sync && say 'finished'
Now we need to get the required proprietry files for our device. We can get these from the device itself. Connect your phone (make sure USB Debugging is enabled) and run the following (for maguro):
Code:
cd /Volumes/android/cm9/device/samsung/maguro/ && ./extract-files.sh
[If you see errors in the output from extract-files.sh, see the Troubleshooting section below]
For Google devices,we can also get them directly from google. For maguro, download the 3 files and extract them to /Volumes/android/cm9. Then,
Code:
cd /Volumes/android/cm9
/Volumes/android/cm9/extract-broadcom-maguro.sh
/Volumes/android/cm9/extract-imgtec-maguro.sh
/Volumes/android/cm9/extract-samsung-maguro.sh
We also need the prebuilts (like ROM manager and Term.apk):
Code:
/Volumes/android/cm9/vendor/cm/get-prebuilts
You can optionally tell the build to use the ccache tool. CCache acts as a compiler cache that can be used to speed-up rebuilds :
Code:
export USE_CCACHE=1 && /Volumes/android/cm9/prebuilt/darwin-x86/ccache/ccache -M 20G
Default is 1GB. Anything between 20GB-50GB should be fine.
Before starting the build, we need to workaround an issue with Lion and compiling the QEMU emulator.
[This step doesn't seem to be needed anymore. QEMU is automatically ignored on OS X/Darwin]
If you build now, you're probably gonna get kernel build errors regarding the missing elf.h header (this error might be device specific). Fortunately, we already have this file downloaded, so we only need to copy it to /usr/local/include:
Code:
cp /Volumes/android/cm9/external/elfutils/libelf/elf.h /usr/local/include
FINALLY, we are ready to build:
Code:
cd /Volumes/android/cm9 && source build/envsetup.sh && brunch
Pick your device from the list and enter the number. For maguro, you could use "brunch maguro" instead and skip the menu. Depending on your system, this will take 30min-4hours.
You should now see a beautiful zip file waiting to be flashed:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Troubleshooting:
The extract script for maguro seems to be a little outdated, as it doesn't pull the gps proprietary blob. You can either use the google provided scripts, or add koush's git repository for your device to your local_manifest.xml.
As explained above, the CM9 source is currently compatible with llvm-gcc. In the future, if llvm-gcc fails to build correctly, you should try installing and compiling using GCC4.2 (the Xcode 3 compiler). You can install apple-gcc4.2 from homebrew:
Code:
brew install https://raw.github.com/Homebrew/homebrew-dupes/master/apple-gcc42.rb
This version of gcc can happily coexist with Xcode 4.x .
So now you have GCC 4.2 installed, but it won't be used unless we update the corresposing environment variables:
Code:
export CC=/usr/local/bin/gcc-4.2 && export CXX=/usr/local/bin/g++-4.2
Notice that using the export command is temporary. If you relaunch Terminal, you will need to set these again. However, this is a good thing, because changing these values permanently (by putting them in ~/.bash_profile) can interfere with other builds.
If you use this method, the build might fail while compiling "external/zlib/x86/adler32.c". It appears that a recent change in zlib has introduced an incompatibility with gcc 4.2. you have to revert the following 2 commits:
Code:
cd external/zlib
git revert dd6786cae3f4493faa6661d5f74db587932f15d7
git revert 13bf40af68236c961542bdee1d4b7c0176bf15a0
Alternatively, you can add topprospect's zlib on github (which has those commits reverted) to your local_manifast.xml. Simply run:
Code:
nano /Volumes/android/cm9/.repo/local_manifest.xml
and add the following line
Code:
<project name="dferg/android_external_zlib" path="external/zlib" remote="github" />
If you get a build error, and your error is not covered here, copy the last 20-30 lines of the build output AND the output from the following command into pastebin and post the link. Hopefully me or someone else will help you.
Code:
echo -e "\nENV:\n$(env)\n\nWHICH GCC\n:$(which gcc)\n\nWHICH G++:\n$(which g++)\n\nWHICH CC:\n$(which cc)\n\nWHICH C++:\n$(which c++)\n\nBREW DOCTOR:\n$(brew doctor)\n\nBREW LIST:\n$(brew list)\n\n/USR/BIN:\n$(ls -l /usr/bin | grep gcc)\n\n/USR/LOCAL/BIN:\n$(ls -l /usr/local/bin | grep gcc)\n\n"
Notes/Extras:
To quickly setup your environment, add an alias like the following to ~/.bash_profile:
Code:
alias cm9env="hdiutil attach PATH-TO-DISK-IMAGE -mountpoint /Volumes/android && cd /Volumes/android/cm9 && source ./build/envsetup.sh && export USE_CCACHE=1"
alias cm9build="cm9env && make clobber && reposync && brunch maguro"
Now you can save time by using "cm9env" to get your environment setup or "cm9build" to compile a clean updated build.
To clear your output directory for a new build, run "make clobber". You probably don't need this if you've only changed a few lines of code.
To cherry pick yet-to-be-merged changes from the gerrit instance:
1. Pick an open commit from CM Gerrit
2. Under list of Patch Sets pick the latest and open cherry-pick tab
3. Check what Git repository the url is pointing e.g. http://review.cyanog...frameworks_base
4. In your CM9 working tree go to the corresponding directory, which in this case is something like ~/your-working-directory/frameworks/base/
5. Now simply paste the whole line seen in CM Gerrit cherry-pick tab e.g. "git fetch http://review.cyanog....rameworks_base refs/changes/00/13100/4 && git cherry-pick FETCH_HEAD"
It should be now included in your next compiled build. When doing repo sync again, cherry picks will be lost.[CREDIT Fihlvein from xda]

thanks! I'll try to keep this topic updated as issues with mac are introduced/resolved.
Nice write up. Thanks.
Before I start again from scratch I have a question. Does this guide apply to previous versions of mac os x (mine is 10.6.8)? I used the official android initializing build environment page & cm7 wiki page for the instructions to setup my build environment.
Also, any tips to switch from macports to homebrew?
In the past I've had to cherry pick to get my OS X build environment set up for CM9. The compile from source fails because I started with macports instead of homebrew (bad idea). I tried to switch to homebrew without success. Any tips to switch from macports to homebrew?
For the sake of keeping this page on topic a pm response is ok if that is what you prefer.
Hi thanks for this !! Helpful one question what do i change so i can do AOSP instead of cm9??

Yes, this guide should work fine on Snow Leopard. It mostly depends on your Xcode version. If you have Xcode 3, you can skip step 1 entirely, since you already have gcc4.2 as part of Xcode.
If you have access to Xcode 4.2 and above, you will need to install gcc4.2 separately, as explained in the guide.
Now regarding Macports, I strongly suggest that you completely uninstall Macports before installing homebrew. Instructions are here: http://guide.macports.org/chunked/installing.macports.uninstalling.html

Full instructions are available on android.com : http://source.android.com/source/initializing.html
If you are using this guide, you need to change the repo initialization command to :
Code:
repo init -u https://android.googlesource.com/platform/manifest
and then do repo sync. You can setup ccache as usual. I don't think AOSP has the "brunch command", so you have to use launch and then make.
Run "lunch" and select an option from the menu. You can find more info about the options here: http://source.android.com/source/building.html. For maguro, you should use "full_maguro-userdebug".
To start the build, use
Code:
make -j$(sysctl -n hw.ncpu)
@ArmanUV. Sounds good & thanks for the input. I'll give the link to macports uninstall a go.
Im a real noob, whats the advantage of compiling from source?
Thanks for the help man !
Hi, thanks for your guide, setting up the repo was no problem at all!
But: I'm getting the following error when building.
Code:
external/zlib/x86/adler32.c: In function ‘adler32_MMX’:
external/zlib/x86/adler32.c:747: error: can't find a register in class ‘GENERAL_REGS’ while reloading ‘asm’

make: *** [out/host/darwin-x86/obj/STATIC_LIBRARIES/libz_intermediates/adler32.o] Error 1
make: *** Waiting for unfinished jobs....
Seems to be a problem with the compiler, but I'm on xcode 4.3 and I've installed gcc-4.2 and set the env vars. Any help?
ArmanUV,
Thanks so much for posting this guide. Very helpful!
Are you having any trouble with errors like this?
Code:
external/zlib/x86/adler32.c: In function ‘adler32_MMX’:
external/zlib/x86/adler32.c:747: error: can't find a register in class ‘GENERAL_REGS’ while reloading ‘asm’
external/zlib/x86/adler32.c:747: error: ‘asm’ operand has impossible constraints
Googling for this error implies that the fix is to use a version of GCC > 4.2. But there does not seem to be a GCC 4.4 in Homebrew.
Thanks again for the guide!
EDIT: Sorry for the double post with empyyy. Seems like there is someone else having my same issue!

You guys seem to have the same issue. What sort of Xcode configuration are you using? Can you post the output from "which gcc","which g++", "gcc -v", "g++ -v" and "cc -v"?

They are pointing to LLVM, but my CC and CXX variables point to:
Code:
env|grep 4.2
CXX=/usr/local/bin/g++-4.2
CC=/usr/local/bin/gcc-4.2
Do I need to add something to PATH? I'm sure I just missed something obvious in your instructions.. Thanks for helping!

Everything checks out. I'm away from my main machine so I can't run a test build, but I suspect that a recent change is causing problems.
Now, regarding the compiler, Setting CC/CXX *should* take care of everything, but I am currently not 100% sure that somewhere in a makefile, these environment variables aren't being ignored. Since I wrote the guide, I noticed a lot of clang warnings in the build, which means that CC/CXX is not honored and /usr/bin/cc and /usr/bin/c++ is being used.
A more robust method of making sure gcc-4.2 is being used is creating symlinks to gcc-4.2 and g++-4.2 :
Code:
ln -s /usr/local/bin/gcc-4.2 /usr/local/bin/gcc
ln -s /usr/local/bin/gcc-4.2 /usr/local/bin/cc
ln -s /usr/local/bin/g++-4.2 /usr/local/bin/c++
ln -s /usr/local/bin/g++-4.2 /usr/local/bin/g++
Obviousely, a systemic method like this has its downsides but it may be the only choice without having to change CM code (especially since I lack the knowledge to do so )
[I recently found out that master aosp is no longer using CC/CXX to find the compiler (see ./build/core/combo/). Instead, it uses "gcc" and "g++" directly, which means that llvm-gcc will be used no matter what env variable you have. Fortunately, unlike cm9, master aosp is supposed to build fine with llvm-gcc (except for qemu, which doesn't matter for device images). ]

Okay, just tried this. I created a new dir (/Volumes/Android/bin) that simply houses those softlinks you recommended. Then I put /Volumes/Android/bin at the beginning of my PATH. That should fix it without breaking the rest of the system, e.g. homebrew.
The GENERAL_REGS problem still exists though. Pretty sure b/c gcc 4.2.1 doesn't understand this construct properly (need a newer version of gcc).
So I backed out the change that introduced this adler32.c.
https://github.com/CyanogenMod/android_external_zlib/commit/13bf40af68236c961542bdee1d4b7c0176bf15a0
The compile is getting farther now. I have to run to work so I'll post later if it succeeds.
The weird thing is: This change was made back in December. Why would it have worked for you?

Build works (and boots!) with the following:
Code:
cd external/zlib
git revert dd6786cae3f4493faa6661d5f74db587932f15d7
git revert 13bf40af68236c961542bdee1d4b7c0176bf15a0
Note the 1st revert is just to avoid massive conflicts seen when reverting the 2nd one by itself. The 2nd revert is the one that really matters here.
So this isn't really a solution.. Seems like we need to move to a newer version of gcc or figure out a patch to adler32.c that makes it gcc 4.2 compatible.

Well, run git status. You'll see that the only conflict is in the comments in zlib.h. So, you can just ignore it.

Nice find. I tried to compile this morning and I ran into the same issue. This is what I don't understand: I did a couple of builds about a week ago without running into this issue. But, the latest commits on zlib are from 2 months ago.
Amazingly, the Xcode 4.3 toolchain (clang and llvm-gcc) builds this external/zlib/adler32.c just fine.
An alternative to this problem is to install an up to date gcc 4.7 :
Code:
brew install https://raw.github.com/Homebrew/homebrew-dupes/master/gcc.rb
and then create symlinks to gcc-4.7/g++-4.7. I have not tested this yet.
[Hey guys Aditya here. After a month or so i'm posting tutorial and basic decompiling compiling using adb command!
THINGS YOU WILL NEED
ON WINDOWS PC
1) Winrar
2) 7zip
3) Java
4) Apktool and adb tools!!!!! (Many tools are available download anyone of them)
5) notepad+ AWESOME THING
ON UBUNTU
1) Java
2) Android SDK
3) APKTOOL ofcourse
Let's get started! I asume you using a Windows PC
First of all download and install JAVA
From here
Download Latest Apktool, extract to :
Windows XP : C:\Document and setting\folder your computer name
Windows 7 : C:\user\folder your computer name
copy your apk & framework-res.apk/SemcGenericUxpRes.apk/framework 2 to same folder with apktool
Now you can start Editing apk
Example Editing Walkman
Open Command Prompt (CMD)
TO DECOMPILE
Code:
java -jar apktool.jar if framework-res.apk
java -jar apktool.jar d semcmusic.apk ( can be whatever name you give to your apk )
Some apks need dependies like tw-framework.apk
Code:
java -jar apktool.jar if framework-res.apk
java -jar apktool.jar if semcgenericuxpres.apk
java -jar apktool.jar d your.apk ( can be whatever name you give to your apk )
Now you can edit what you like to. E.g. Res layout etc!
(For more detalis refer Post #3)
TO COMPILE
To compile back the edited apk
Code:
java -jar apktool.jar yourapkname.apk
For signing apk just drop the android manifest and meta inf of older apk or original apk!!!!!!
F.A.Q
A.I'm getting error while compiling apk??
Check if you have installed framework-res.apk most of compiling errors are becoz of this
B.Can apktool batch decompile and recompile apk's??
Yes,many of modded apk manegers or tools can batch decompile and recompile apk's!!
C.Can i MOD any system app using apk tool?
Yes it can mod all types of apk's just make sure you have correctly installed framework and all other dependices!!!!
D.My modded apk is not working! What should i do???
This question is mostly asked to me! Firstly check weather you have put the Meta-Inf from original APK as this folder contain signatures required for apk to get install.Secondly if you have modded some xml check its correct or some code or values are wrong.If any values or wrong code can lead us to FC or Bootloop..!!!
Using ADB and taking logcat!!!!!
USING ADB AND TAKING LOGCAT
What ia adb??
adb stands for Android Debugging Bridge
For what it is used for
adb is commonly used to pull,push,taking system dumpFOR TAKING LOGCAT
What you will need
On windows
1) Java (Hmmm not needed but u should have. )
2) adb tools by me http://d-h.st/vHJ
Now to make it easy first of all check you have enabled USB Debugging in phone its in Developer Options.
PROCDURE
Make a new folder in C Drive
Extract these tools into it (Asume you folder name is adb)
Now open cmd
Code:
type cd..
cd.. again
cd adb
adb
Now you have installed adb on your PC!
TAKING LOGCAT
Code:
adb logcat>logcat.txt
For only redio related log type
Code:
adb -r logcat>logcatr.txt
For only errors type
Code:
adb -v logcat>logcate.txt
Push and pulling apps from system!
Pushing Apps
Pushing app is installing app on its intenrnal memory!Its simple and doesn't need extra powers!
Code:
adb push yourappname.apk /system/app or /system/framework
Place the app in the adb folder
Pulling Apps
Pulling app is to take out your system apps or frameworks etc!
Code:
adb pull /system/app or /framework yourapp.apk
By this method you can take a system dump
Code:
adb pull /system
Understanding Logcats!!!!!
Some keyword's that represent's error'
Code:
"E/" - error
"E/dalvikvm" - possibly crucial system error
"No such file or directory" - says it all
"couldn't" - android likes that, mostly shows faulty things.
"fail"/"failed" - mostly crucial error
"W/"/"warning" - says it all, but not always warn could be a boot failure cause
"exception"(especially NullPointerException) - points you that something went wrong in framework or application work
These type of errors help us understand the error's and we can easily call out from these bugs or errors!!!
Most common errors occuring in an logcat!
"couldn't find native method", the most common reason of a bootloop.
This error causes most of bootloop problems!!!
For example
Code:
E/dalvikvm( 100): ERROR: couldn't find native method
E/dalvikvm( 100): Requested: Landroid/view/GLES20Canvas;.nStartTileRendering:(IIIII)V
E/JNIHelp ( 100): RegisterNatives failed for 'android/view/GLES20Canvas', aborting
As you can see! The main reson for this error is smali present in android/view of framework.jar called GLES20Canvas.smali
This happens while you are trying to port ROMS!!!!
Now if you are having bugs in other apkor jars how can u find ahem! i.e logcat gives us only the location of smali files and not the name of apk or jar! For that you have to study hole android code sources! Some common folders i have posted here!!
Code:
"com/android/server" - services.jar (there is the same folder at framework.jar but most likely you don't need to touch it).
another place we could be mixed up:
"com/android/internal" - framework.jar
"com/android/internal/policy/impl/" - android.policy.jar
for framework.jar path ends up on internal, which represents telephony folder. policy/impl is the only android.policy.jar folder.
Other frameworks are actually not used in port as they contain core android functionality which is common.
Simple MOD's
Now you guy's have idea about how to take a Logcat,use adb,use apktool.
NOW SOME REAL STUFF
MOD's Related to SystemUI.apk
We will start with simple MOD's! Like replacing icons and to some extend changing layout!
Now we will start will replacing icons inside the SystemUI.apk
First of all pull app from /system/app using adb Refer #2
Then copy that app to apktool folder! Type this cmd
Code:
java -jar apktool.jar d SystemUI.apk
Now go to out folder of SystemUI.apk!
Will find META-INF! RES! ANDROID.manifest
Now Navigate to res/drawable-hdpi as our device uses HPDI
You will find many icons now be carefull here! If youare expert n photoshop or any bitmap editor eit these icons! Or search it! Google it you will find many!
Replace these default icons by ur edited once or downloaded once!!
XML EDITING
Some XML's are not so complicated as other once! Some xml's have just true or false! Example
Code:
<bool name="config_hardwareAccelerated">true</bool>
This tells me that Hardware Acceleration is enabled you can disable it by replacing true by false! You just need to experiment around!
Smali Editing!
Coming soon!
Patching!
Coming soon :d
