ClassCastException when trying to load plugin

[adamleko]

When installing a plugin on more recent versions of Android, Aware crashes with the following ClassCastException:

The underlying cause is the unconditional class cast which only works if the application icon is actually an BitmapDrawable instance.

Newer versions of Android that use adaptive icons (past SDK v26 or so) will always return a AdaptiveIconDrawable when asking for the icon via PackageManager. A simple fix for this is to check the instance type before doing a cast, otherwise drawing the icon on a Canvas to get a bitmap reprsentation.
