Develop a shareware named common language extension middleware(CLE) independently using c/c++ language in spare time. The middleware supports mixed-languages call between java, c/c++, lua, python, php, and c#, and supports win32, linux, and android platform. Android version is released at google code, http://code.google.com/p/cle-for-android.2. Finish porting and encapsulation of graphic library “Anti-Grain Geomet” to cle using c++. Thus enable the library can be called using multiple script languages and on win32, linux, and android platform. Android version is released at google code, http://code.google.com/p/agglib-for-android.3. Design and implement an 2D render engine based on OpenGL ES2.0 and CLE, which uses c++ language, supports java and lua, and can run on win32 and android. Android version is released at google code, http://code.google.com/p/gles-for-android.
