I searched and did not find a complete code example of compute shader, so I publicized here when I finished it. And it is also a record in case that I myself may need it some time later.
To build within Linux, just run 'make'.
If there's build issue, try to install the necessary libraries, such as the following:
apt-get install libgles2-mesa-dev libegl1-mesa-dev
Steps to build within Andriod source tree.
1. cd your_path_to_android/frameworks/native/opengl/tests/
