Starting with Android N, ImageView doesn't properly forward visibility events to its underlying drawable if activity transitions are used. This sample app showcases the issue.
This sample app has 2 Activities. The main one holds an ImageView that displays a debug drawable and has a button to transition to Activity 2 and a toggle to enable / disable activity transitions. The debug drawable just prints whether it is visible and changes the background color accordingly (green = visible, red, invisible).
If your target SDK is >= 24 and activity transitions enabled, you'll notice that when you transition from A -> B and go back to A, the Drawable in A will have its visibility set to false instead of true. Everything works properly if transitions are disabled.
