Build Android on Gentoo x86_64 (amd64) [English version]

I created clean user to compile Android.

Workaround for Python 2. When you start repo on recent Gentoo (which uses Python 3), next error will rise:

# repo
  File "/usr/bin/repo", line 180
    except OSError, e:

SyntaxError: invalid syntax

What I done to fix this (emerge Python 2, create symbolic link to it under user account):

# emerge -av python:2.7
$ mkdir ~/bin
$ export PATH="~/bin:$PATH"
$ cd ~/bin
$ ln -s /usr/bin/python2 ~/bin/python

Emerge Sun JDK to compile Android (1.6 version needed) and set it as user java-vm:

# emerge -av sun-jdk
$ eselect java-vm list

Find sun-jdk and run next command with corresponding number.

$ eselect java-vm set user 2

Install x86 (32 bit) libs for Android to build.

# emerge -v emul-linux-x86-baselibs

For me there are errors corresponding to Nullable class in sdk/chimpchat project. To fix this I compiled host jsr305 library which contains refence to @Nullable and added it to project manually.

# emerge -v jsr305
$ croot
$ nano sdk/chimpchat/src/Android.mk

Now add jsr305 to local java libraries. Then link it to system one (for me ./external/jsr305/ dont compile host library).

$ ln -s /usr/share/jsr305/lib/jsr305.jar /home/john/android/ics/out/host/linux-x86/framework/jsr305.jar
