ActivityTransitionResult

AI-generated Key Takeaways

• ActivityTransitionResult represents the results of detected activity transitions, containing a list of ActivityTransitionEvent objects.

• You can extract an ActivityTransitionResult from an Intent using extractResult() and check for its presence with hasResult().

• getTransitionEvents() provides access to the list of transition events within the result, ordered chronologically.

• ActivityTransitionResult can be created using a list of ActivityTransitionEvent objects, which must be sorted in ascending order of time.
