I am trying to display banner Ad in my game so i am using revmob to display both banner Ad and fullscreen Ad. Now full screen Ads are displaying but Banner Ad is not displaying getting null poinet exception in view.addView(banner).

enter code herepublic class MainActivity extends Activity {
private CCGLSurfaceView mGLSurfaceView;
private boolean isCreated = false;
public static FrameLayout m_rootLayout;

public static String APPLICATION_ID = "514c7c57cee0500d00000001";
public static RevMob revmob;

// This is used to display Toast messages and is not necessary for your app
@Override
protected void onCreate(Bundle savedInstanceState) {
    if (!isCreated) {
        isCreated = true;
    } else {
        return;
    }

    super.onCreate(savedInstanceState);

    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);

    setContentView(R.layout.activity_main);

    revmob = RevMob.start(this, APPLICATION_ID);
    displayRevMob();


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


    CCDirector.sharedDirector().attachInView(mGLSurfaceView);

    getScaledCoordinate();

    Global.assetManager = getAssets();
    Global.context = this;
    Global.loadUserInfo();
    CCScene scene = CCScene.node();
    scene.addChild(new SplashScene(), -1);

    CCDirector.sharedDirector().runWithScene(scene);




    //-------------IAP-----------------------
    Log.d(TAG1, "Creating IAB helper.");
        mHelper = new IabHelper(this, base64EncodedPublicKey);
        mHelper.enableDebugLogging(true);
        Log.d(TAG1, "Starting setup.");
        mHelper.startSetup(new IabHelper.OnIabSetupFinishedListener() {
            public void onIabSetupFinished(IabResult result) {
                Log.d(TAG, "Setup finished.");

                if (!result.isSuccess()) {
                    // Oh noes, there was a problem.
                    complain("Problem setting up in-app billing: " + result);
                    return;
                }

                // Hooray, IAB is fully set up. Now, let's get an inventory of stuff we own.
                Log.d(TAG, "Setup successful. Querying inventory.");
                mHelper.queryInventoryAsync(mGotInventoryListener);
            }
        });

The problem is in here:

ViewGroup view = (ViewGroup) findViewById(R.id.banner);
view.addView(banner);

Apparently findViewById() returns null, which means that View called banner was not found in your xml layout file.

You have R.layout.activity_main set as your content view. Ensure, that you have View with banner id in this file.
