Line 93 in my source is: Drawable image = vi.getContext().getResources().getDrawable(imageResource);
I've attempted to set a break point at the line above it and step over it but when I do I get:

المحلول
Resources$NotFoundException - This exception is thrown by the resource APIs when a requested resource can not be found.
Problem is here
int imageResource = vi.getContext().getApplicationContext().getResources().getIdentifier(uri, null, vi.getContext().getApplicationContext().getPackageName());
