Subject: [PATCH] Prevent RemoteViews crashing SystemUi
Catch canvas drawing exceptions caused by unsuported image sizes.
Test: 1. Post a custom view notification with a layout
containing an ImageView that references a 5k x 5k image
2. Add an App Widget to the home screen with that has the
layout mentioned above as preview/initial layout.
