public class FlyingPanda extends Activity{
/** Called when the activity is first created. */

public static FlyingPanda app;

public static CCGLSurfaceView mGLSurfaceView;
private boolean isCreated = false; 

private static final String AD_INTERSTITIAL_UNIT_ID = "df2cce209f194168";

/** The interstitial ad. */
private InterstitialAd interstitialAd;
private AdView adView = null;


@Override

    if( !isCreated ){
        isCreated = true;

    //my code

    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);
    
    //my code

    AdView mAdView = (AdView) findViewById(R.id.adView);
    AdRequest adRequest = new AdRequest.Builder().build();
    mAdView.loadAd(adRequest);
    //my code

    RelativeLayout layout = new RelativeLayout(this);
    layout.setLayoutParams(new RelativeLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));
    
    mGLSurfaceView = new CCGLSurfaceView(this);
    
    
    
    layout.addView(mGLSurfaceView);
    
    setContentView(layout);
    
    
    
    // Create an ad request. Check logcat output for the hashed device ID to
    // get test ads on a physical device.
        //AdRequest adRequest = new AdRequest.Builder().build();
        //adView.loadAd(adRequest);
        

    //-----------------------------------------------------Interstitial Add
