Attached with this project (includes sample images).
The issue is if you toggle the buttons back and forth, it restarts the app. On my device, you have to tap 2 red buttons before it crashes.
The app should be toggling the two buttons without crashing. There should only be one white and one red imageView at any one time.
The white image means the 'button' (which is an imageView) is currently pressed down. The red image means it is currently not selected.
