Method Detail

getInstance

public static ChoreographerCompat getInstance()

Returns:

a ChoreographerCompat instance for the main thread. This should really be on ChoreographerCompat but interfaces don't support static methods until Java 8.

NB: Unlike android.view.Choreographer#getInstance(), this method ALWAYS returns an instance that posts to the MAIN THREAD android Choreographer (and main thread Handler for API<16).

setInstance

public static void setInstance(ChoreographerCompat choreographerCompat)

Set the ChoreographerCompat instance for tests.
