Memory leak using AdMediator with pubCenter and AdMob

Question

I'm using the latest version of AdMediator in my Silverlight Windows Phone 8.0 application.

I'm using it with Google AdMob and Microsoft pubCenter.

I've noticed that, when I navigate to other pages, AdMediatorControl doesn't release its memory, in fact after 10~15 navigations (depending on how many ads I put on the pages) the application crashes with an OutOfMemoryException.

If I remove the AdMediatorControl from the XAML this doesn't happen and the memory is correctly released (I can see it in Windows Phone Developer Power Tools).

I tried to set my AdMediatorControl instance to null on the event OnNavigatedFrom but this doesn't change anything.

I can't publish my app because of this. Could you please help me?

Answer 1

Solved! I just had to use the same instance for the whole app.

Here's how I solved the issue:

I've removed AdMediator and instantiated the banners manually using C#. So, I've created a single instance of AdView and AdRequest (public static) in the class App which I initialize in the event Application_Launching.

Then, in every page where I needed a banner, in the event OnNavigatedTo I set the AdView of App class as a children of the page Grid (ContentGrid) and launch the LoadAd method on the AdRequest instance of the App class.

Then, in the event OnNavigatedFrom, I remove the AdView from the Children of the Grid.

Done! No more memory leak! :D
