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.
|
