First off, i want to say that this is information taken from various sources, the most predominant being start [CVPCS Android Wiki] and Get Android Source Code | Android Open Source . The only thing i contributed to this guide was that i condensed it a bit and customized it specifically for the incredible, although the only thing that differs from the incredible to other devices it the vendor setup.
WARNING: This is NOT FOR NOOBS. If you havent had much experience with working with the Android System, you should not even think about using this guide.
This is a guide for building AOSP on Ubuntu Lucid Lynx (10.04). If you have Mac, i cant help you much. If you have Windows, i strongly reccommend that if you havent already done so, download Ubuntu onto a CDROM and run wubi.exe to trial ubuntu.
THERE WILL NEVER BE A GUIDE FOR BUILDING ON WINDOWS!!!!!!!!!
Ok, so now that all that stuff is over, heres your guide:
First, we want to install java5. Java6, the newest java is NOT supported due to @Override incompatibilities
Code: sudo apt-get install git-core gnupg sun-java5-jdk flex bison gperf libsdl-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl libncurses5-dev zlib1g-dev
You might also want Valgrind, a tool that will help you find memory leaks, stack corruption, array bounds overflows, etc.
Code: sudo apt-get install valgrind
Set the system to use the right version of java by default:
Code: sudo update-java-alternatives -s java-1.5.0-sun
Now to install the repo
Code: cd ~/
Download thereposcript and make sure it is executable:
Code: curl http://android.git.kernel.org/repo >~/bin/repo chmod
Create an empty directory to hold your working files:
Code: mkdir mydroid
Run “repo init” to bring down the latest version of Repo with all its most recent bug fixes. You must specify a URL for the manifest:
Code: repo init -u git://android.git.kernel.org/platform/manifest.git -b froyo
When prompted, configure Repo with your real name and email address. If you plan to submit code, use an email address that is associated with a Google account .
A successful initialization will end with a message such as repo initialized in /mydroid
Now to download all the files you need.
To pull down files to your working directory from the repositories as specified in the default manifest, run
Code: repo sync
NOTE: The repo sync does tend to take a little long, after all it is 2.1 gigs of files
Now to verify the git tags. Doing this wont affect the build, but it doesnt hurt.
In your command prompt, type:
Code: gpg –import
and paste this LONG key into the empty space:
—–BEGIN PGP PUBLIC KEY BLOCK—–
Version: GnuPG v188.8.131.52 (GNU/Linux)
—–END PGP PUBLIC KEY BLOCK—–
And press ctrl d to exit the gpg mode and verify the git tags.
Now to setup the vendor overlay:
git clone http://github.com/koush/android_device_htc_inc.git inc
Code: cd ~/android/system/device/htc/inc
NOTE: ADB Must be in your path. You also have to edit the extractfiles.sh so that it reads ./adb pull and not adb pull (add nix boxes)
Now to build the build:
Code: cd ~/mydroid/system
make -j`grep ‘processor’ /proc/cpuinfo | wc -l` otapackage
Ok, lets say you get an error. most likely its librpc. What you have to do is
Code: make clean
Also, you may have to edit some files, add in some proprietaries, so whatch those errors carefully! (also, you may get an error about recovrty not being made…all you have to do is replace the word “mahimahi” in the file to “inc”)
If the build fails because of java, enter this:
Code: export ANDROID_JAVA_HOME=$JAVA_HOME
This is a bit of a workaround for now, but this is how i did it:
1) Drag and drop superuser.apk from an existing rom and prop it into system/app of your AOSP rom
2) DRag and drop the su binary from an existing rom and drop it into your AOSP rom (in system/bin)
go to the root of the rom (in the part where it says “system, Boot.img, META-Inf, recovery-prerec”) and delete meta-inf, recovery-prerec. Add in the Meta-INF from HERE (http://bit.ly/gBO1N1), and viola, an AOSP rom with root is born!
