HelloWorld android build failed

First time, I built HelloWorld android project successfully.
But run Android app failed with error:
Unexpected resume of com.android.launcher while already resumed in org.cocos2dx.application

And then I found some topic said res should be refreshed first, but the same error occurred after that.

Finally I modified /Classes/HelloWorldScene.cpp, changed “CloseNormal.png”, “CloseSelected.png”, “helloworld.png” to lower case.
and then run ./build_native.sh got errors:

error: GLES/glplatform.h: No such file or directory

Can anyone help me to resolve the problem?
THX!
