In cocos2d-x 2.0.3 ...Cocos2d-x Lib java files has been considered as a different project only So import that project in the eclipse

Lets make it Simple

You will see libcocos2dx project in eclipse ...Keep this project open always otherwise your projects will give error on the syntax of library

Also additional information to run build-native.sh from eclipse only , Right Click Project ->C/C++ Build Uncheck Use Default Build COmmand and add following bash ${workspace_loc:/YourProjName}/build_native.sh NDK_DEBUG=1 V=1

Good Luck ..If any question please feel free to ask

就是先把cocos2d-2.0-x-2.0.3/cocos2dx/platform/android/java里面的项目加载进来，然后就可以了。

之后右击项目运行，在手机上就可以看到cocos的启动画面了。
