Research direction
Locate the UI test for Issue1588 in the ControlGallery project (likely under Xamarin.Forms.Controls.Issues). Reproduce the crash by running the test on an Android emulator and clicking the 'Animate' button. Use adb logcat to capture the stack trace. The fix may be a null reference or threading issue in the animate logic; check the ViewModel or code behind for the button handler.
