Android Make file generator for cocos2dx 2.2.6 project running with Android studio:

1. Copy AndroidMakeGenerator.java to your proj.android-studio -> app -> jni folder
2. Open terminal and compile it javac AndroidMakeGenerator.java
3. Run output class java AndroidMakeGenerator then an output file android.mk file will be created under jni folder
