OutOfMemoryError x loadAd (adRequest) x AdActivity

Good evening.

Does anyone know the AdActivity class? And does anyone know if I can use it seamlessly with finish() ?

Context acontext = null; 

AdActivity adActivity = (AdActivity) acontext; 

adActivity.finish();

I'm having problems with OutOfMemoryError that occurs when I do not call anuncioView.loadAd(adRequest) and then restart the app.

Can anyone help me?

Thanks.
