Cocos2D Android应用程序崩溃

Question

我正在开发Cocos2D android应用程序，这是我的第一个示例应用程序。 cocos2d-android.jar我下载并将其附加在/ libs文件夹中。这是我的classActivity＆amp; logcat输出

CocosMainActivity ：

     CCGLSurfaceView mGLSurfaceView;
     @Override
     protected void onCreate(Bundle savedInstanceState) {
       requestWindowFeature(Window.FEATURE_NO_TITLE);
       super.onCreate(savedInstanceState);

       setContentView(R.layout.activity_cocos_main);



           getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
           getWindow().setFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON, WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

           mGLSurfaceView = new CCGLSurfaceView(this);
           setContentView(mGLSurfaceView);
}


@Override
protected void onStart() {
    // TODO Auto-generated method stub
    super.onStart();
    CCDirector.sharedDirector().attachInView(mGLSurfaceView);
    CCDirector.sharedDirector().setDeviceOrientation(CCDirector.kCCDeviceOrientationPortrait);

    CCDirector.sharedDirector().setDisplayFPS(true);
    CCDirector.sharedDirector().setAnimationInterval(1.0f/60);

    CCScene scene = CocosLayer.scene();
    CCDirector.sharedDirector().runWithScene(scene);
}

@Override
protected void onPause() {
    // TODO Auto-generated method stub
    super.onPause();
    CCDirector.sharedDirector().pause();
}
 @Override
protected void onResume() {
    // TODO Auto-generated method stub
    super.onResume();
     CCDirector.sharedDirector().resume();
}

 @Override
protected void onDestroy() {
    // TODO Auto-generated method stub
    super.onDestroy();
     CCDirector.sharedDirector().end();
}

 static class CocosLayer extends CCLayer{
        CCLabel label;
        CCSprite iconImage;
        public static CCScene scene(){
            CCScene scene = CCScene.node();
            CCLayer layer = new CocosLayer();
            scene.addChild(layer);

            return scene;
        }
        protected CocosLayer(){
            this.setIsTouchEnabled(true);

            //add label
            label = CCLabel.makeLabel("cocos2d Droid Label", "Droid Sans", 30);
            label.setPosition(CGPoint.ccp(164, 240));
            addChild(label,0);

            //add image
            iconImage = CCSprite.sprite("ic_launcher.png");
            iconImage.setPosition(CGPoint.make(100, 100));
            addChild(iconImage,0);

        }

    }

LogCat ：

我将这个“ic_launcher.png”放在assets文件夹中。
