java.util.concurrent.TimeoutException: android.view.ThreadedRenderer.finalize() timed out after 10 seconds

Since KitKat, I have issues withWebViews(freeze, crash)

I have resolved these issues deactivating hardware acceleration forwebViews. It could work for you.

if(Build.VERSION.SDK_INT>=19)// KITKAT{webView.setLayerType(View.LAYER_TYPE_SOFTWARE,null);}
