to BackAnimation. The original MotionEvent instance may have been recycled by the time BackAnimation processes it, since BackAnimation runs in a different thread. This could cause crashes from both Java side and native side, as described in b/233163975#comment11. We work around this by passing the numerical values that BackAnimation need instead of the MotionEvent itself. Test: Swipe back in various scenarios. Make sure back can be triggered. Try cancel. Make sure back can be cancelled. Test: atest BackAnimationControllerTest Bug: 233163975 Change-Id: I4792debc705536b49d1caafcc43e5466941c1d43 Merged-In: I4792debc705536b49d1caafcc43e5466941c1d43
WM Shell Test
This contains all tests written for WM (WindowManager) Shell and it's currently divided into 3 categories
- unittest, tests against individual functions, usually @SmallTest and do not require UI automation nor real device to run
- integration, this maybe a mix of functional and integration tests. Contains tests verify the WM Shell as a whole, like talking to WM core. This usually involves mocking the window manager service or even talking to the real one. Due to this nature, test cases in this package is normally annotated as @LargeTest and runs with UI automation on real device
- flicker, similar to functional tests with its sole focus on flickerness. See WM Shell Flicker Test Package for more details
