- Remove BaseNfcPreferenceController.
- NfcPreferenceController inherit from TogglePreferenceController.
- AndroidBeamPreferenceController inherit from BasePreferenceController.
- Override getIntentFilter in NfcPreferenceController to listen changes.
- Add an API (hasAsyncUpdate) into BasePreferenceController to
distinguish the setting which is updated asynchronously.
