Remarks
Jank information to be fed back via OnJankDataListener.
Apps may register a OnJankDataListener to get periodic batches of jank classification data from the ( composer regarding rendered frames. A frame is considered janky if it did not reach the display at the intended time, typically due to missing a rendering deadline. This API provides information that can be used to identify the root cause of the scheduling misses and provides overall frame scheduling statistics.
This API can be used in conjunction with the FrameMetrics API by associating jank classification data with FrameMetrics data via the frame VSync id.
