Class EventSource

java.lang.Object

ru.noties.requirements.EventSource

public abstract class EventSource
extends java.lang.Object

Helper class to receive `onActivityResult` and `onRequestPermissionsResult` events from activity or fragment. Once instance is obtained via create() method, actual events must be redirected to this instance by calling onActivityResult(int, int, Intent) and onRequestPermissionsResult(int, String[], int[]). Both of them return a boolean indicating if event was consumed.
