Download the android source code:
Mkdir ~ /Bin
PATH = ~ /Bin: $ PATH
Curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo> ~ /Bin/repo
Chmod a + x ~ /Bin/repo
Repo init-u https://android.googlesource.com/platform/manifest-B android-4.2.1_r1
Repo sync)

(You may need to upgrade git:

Upgrade git:

Sudo apt-add-repository PPA: Git-core/PPA
Sudo apt-Get update
Sudo apt-Get install git

Configure git (if not configured, the repo will also require configuration ):

Git config -- global user. Email "your email"

Git config -- global user. Name "your name"

)

Set ccach:

(Ccach can accelerate recompilation)

Gedit ~ /. Bashrc

Add:

# Set Android complition ccache

Export use_ccache = 1

Export ccache_dir = <path-to-your-Cache-directory> (optional, default location ~ /. Ccach)

Source ~ /. Bashrc

Run the following command in the android source code directory:

Prebuilts/MISC/linux-x86/ccache-M 50g (I didn't set this, I don't know how big the default size is)

Compile and run:

source build/envsetup.sh

lunch full-eng

Make-J4 (J depends on how many threads your computer CPU can run at the same time)

Emulator

Modify environment variables:
Gedit ~ /. Bashrc
Source ~ /. Bashrc
Go to the compiled Android Folder:
Cd WO *
Source build/envsetup. sh
Lunch full-eng
