Public methods

flush

Added in API level 36

public void flush ()

Request a flush of any pending jank classification data.

May cause the registered listener to be invoked inband. Since jank is tracked by the system compositor by surface, flushing the data on one listener, will also cause other listeners on the same surface to receive jank classification data.

removeAfter

Added in API level 36

public void removeAfter (long afterVsync)

Schedule the removal of the registered listener after the frame with the provided id.

Because jank classification is only possible after frames have been displayed, the callbacks are always delayed. To ensure receipt of all jank classification data, an application can schedule the removal to happen no sooner than after the data for the frame with the provided id has been provided.

Use a value <= 0 for afterVsync to remove the listener immediately, ensuring no future callbacks.

Parameters
`afterVsync`	`long`: the id of the Vsync after which to remove the listener
