Step to compile/create System image after AOSP source code download

1. After successful download of AOSP code, First, check your JDK installation
   For android AOSP source code compilation, we need OpenJDK
   For Android N we need OpenJDK version “1.8.0_xxxx” and for L or M we need
   OpenJDK version “1.7.0_xxx”
2. Installing required packages (Ubuntu 14.04)
   You will need a 64-bit version of Ubuntu. Ubuntu 14.04 is recommended.

sudo apt-get install git-core gnupg flex bison gperf build-essential \
zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 \
lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z-dev ccache \
libgl1-mesa-dev libxml2-utils xsltproc unzip

For more detail follow the link:-

3. Then run the following command in sequence:-

source build/envsetup.sh
lunch (Enter this command and then choose your target from the given option. Just pass the number like 1)
make -j4 (make command based on CPU Core and RAM size you can choose like -j8, j16 etc..)

That’s it. For the fresh build, it will take a couple of hours (1 or 2 or 3).
