/**
 * Rudimentary methods wrapping the use of a LocalBroadcastManager to simplify the process
 * of notifying other classes when a particular fragment is notified that a permission is
 * granted.//from w ww .j a v a  2  s  . c om
 *
 * To be notified when a permission has been granted, create a new broadcast receiver
 * and register it using {@link #registerPermissionReceiver(Context, BroadcastReceiver, String)}
 *
 * E.g.
 *
 * final BroadcastReceiver receiver = new BroadcastReceiver() {
 *     @Override
 *     public void onReceive(Context context, Intent intent) {
 *         refreshContactsView();
 *     }
 * }
 *
 * PermissionsUtil.registerPermissionReceiver(getActivity(), receiver, READ_CONTACTS);
 *
 * If you register to listen for multiple permissions, you can identify which permission was
 * granted by inspecting {@link Intent#getAction()}.
 *
 * In the fragment that requests for the permission, be sure to call
 * {@link #notifyPermissionGranted(Context, String)} when the permission is granted so that
 * any interested listeners are notified of the change.
