How to download Android source code
Source code of Android can be downloaded by following these steps:
$ mkdir ~/bin $ PATH=~/bin:$PATH $ curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo $ chmod a+x ~/bin/repo $ mkdir WORKING_DIRECTORY $ cd WORKING_DIRECTORY $ repo init -u https://android.googlesource.com/platform/manifest $ repo init -u https://android.googlesource.com/platform/manifest -b android-4.0.1_r1 $ repo sync
android-4.0.1_r1 can be replaced by any version displayed in the previous step. The download process will take a while.
