1. Webview is best to use dynamic addview, not directly in the layout file

 

2. Do these when closing the Activity

if( mWebview != null ){

mWebview.clearHistory();

mWebview.clearCache(true);

mWebview.freeMemory();

//mWebview.pauseTimers();//This should be paired with resumeTimers()

 

ViewGroup parent = (ViewGroup) mWebview.getParent();

       if (parent != null) {

           parent.removeView(mWebview);

       }

       mWebview.removeAllViews();

       mWebview.destroy();

 

       mWebview = null;

}

 

if(mAdDialog != null){

mAdDialog.dismiss();

}
