Callback for the result from requesting permissions. This method is invoked for every call on #requestPermissions(String[], int).

Note: It is possible that the permissions request interaction with the user is interrupted. In this case you will receive empty permissions and results arrays which should be treated as a cancellation.

Parameters:

permissions - The requested permissions. Never null.

grantResults - The grant results for the corresponding permissions which is either PackageManager.PERMISSION_GRANTED or PackageManager.PERMISSION_DENIED. Never null.

Returns:

True if the listener has consumed the event, false otherwise.
