admob banner ad declaration in class giving errors in android

问题

In My android game I'm declared admob banner ad in class instead of layout. I had used the following code in onSetContentView:

 protected void onSetContentView() {
        final FrameLayout frameLayout = new FrameLayout(this);
        final FrameLayout.LayoutParams frameLayoutLayoutParams =
                new FrameLayout.LayoutParams(FrameLayout.LayoutParams.FILL_PARENT,
                                             FrameLayout.LayoutParams.FILL_PARENT);

        final AdView adView = new AdView(this, AdSize.BANNER, "ca-app-pub-7554016237953661/7036151237");

        adView.refreshDrawableState();
        adView.setVisibility(AdView.VISIBLE);
        final FrameLayout.LayoutParams adViewLayoutParams =
                new FrameLayout.LayoutParams(FrameLayout.LayoutParams.WRAP_CONTENT,
                                             FrameLayout.LayoutParams.WRAP_CONTENT,
                                             Gravity.CENTER_HORIZONTAL|Gravity.BOTTOM);


        AdRequest adRequest = new AdRequest();
        adView.loadAd(adRequest);

        this.mRenderSurfaceView = new RenderSurfaceView(this);
        mRenderSurfaceView.setRenderer(mEngine);

        final android.widget.FrameLayout.LayoutParams surfaceViewLayoutParams =
                new FrameLayout.LayoutParams(super.createSurfaceViewLayoutParams());

        frameLayout.addView(this.mRenderSurfaceView, surfaceViewLayoutParams);
        frameLayout.addView(adView, adViewLayoutParams);

        this.setContentView(frameLayout, frameLayoutLayoutParams);

    }

And in my manifest file i had used:

<android:name="com.google.ads.AdActivity"            
android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize" />         

Error log returns the following error:

I suppose you're using a build target of 19. Your code will compile but will crash on devices/emulators running on android < Api Level 19 because,

the FrameLayout.LayoutParams(FrameLayout.LayoutParams source) constructor is available from API 19. You should cast to the older target API 1 FrameLayout.LayoutParams (ViewGroup.MarginLayoutParams source). Modify your code as follows:

 final FrameLayout.LayoutParams frameLayoutLayoutParams =
               ((ViewGroup.MarginLayoutParams) (new FrameLayout.LayoutParams(FrameLayout.LayoutParams.FILL_PARENT,
                                             FrameLayout.LayoutParams.FILL_PARENT)));

 final FrameLayout.LayoutParams adViewLayoutParams =
               ((ViewGroup.MarginLayoutParams) (new FrameLayout.LayoutParams(FrameLayout.LayoutParams.WRAP_CONTENT,
                                             FrameLayout.LayoutParams.WRAP_CONTENT,
                                             Gravity.CENTER_HORIZONTAL|Gravity.BOTTOM)));

This problem is not caused by admob as is mentioned in your logcat output.

It says FrameLayout.LayoutParams is not a method. Wherever you have: FrameLayout.LayoutParams replace it with ViewGroup.LayoutParams and it should solve your problem.
