强调一下Android部分有个错误的地方：

public Cocos2dxGLSurfaceView(final Context context) {
    super(context);
    this.setEGLConfigChooser(5, 6, 5, 0, 16, 8); // 添加此句

    this.initView();
}

如果按照博文里面的位置设置有些机型会启动不起来，直接crash。

应该放在：

public abstract class Cocos2dxActivity extends Activity implements Cocos2dxHelperListener {
    public Cocos2dxGLSurfaceView onCreateView() {
        Cocos2dxGLSurfaceView glSurfaceView = new Cocos2dxGLSurfaceView(this);
        glSurfaceView.setEGLConfigChooser(5, 6, 5, 0, 16, 8);
        return glSurfaceView;
    }
}
