Pull request overview
Fixes incorrect numberOfPointers reported to JS on Android for ACTION_POINTER_UP events (Android includes the lifted pointer in MotionEvent.pointerCount for that event), aligning the reported pointer count with the number of pointers remaining on screen and preventing pinch “jump” scenarios like #3435.
Changes:
- Adjust
numberOfPointerscalculation on Android to reportpointerCount - 1forACTION_POINTER_UP. - Preserve existing behavior for
ACTION_UP/ACTION_CANCELto stay consistent with iOS behavior as noted in the PR description.

Description
Fixes #3435
Android includes the pointer being lifted in the
ACTION_POINTER_UPevent, so the event where the pointer is lifted is sent withnumberOfPointers = 2. This PR changes that so thenumberOfPointersis reported asn - 1forACTION_POINTER_UPevents.Note: The same applies to
ACTION_UPandACTION_CANCELbut I didn't include them to keep the behavior the same as on iOS.Test plan
Reproducer from #3435
