I want to update recycler view through Alarm Manager at a sepcific interval. To this I'm using BroadcastReceiver to receive the task completion:

public class MyFragment extends Fragment {

    // TODO: Customize parameter argument names
    private static final String ARG_COLUMN_COUNT = "column-count";
    // TODO: Customize parameters
    private int mColumnCount = 1;
    private MyInterface mListener;
     private View view1;
    RecyclerView recyclerView;


    private BroadcastReceiver receiver = new BroadcastReceiver() {

        @Override
        public void onReceive(Context context, Intent intent) {
            /*Bundle bundle = intent.getExtras();
            if (bundle != null) {
                String string = bundle.getString("");
                int resultCode = bundle.getInt("");

            }*/
            
        }
    };

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        if (getArguments() != null) {
            mColumnCount = getArguments().getInt(ARG_COLUMN_COUNT);
        }
    }

    @Override
    public void onResume() {
        super.onResume();
         registerReceiver(receiver, new IntentFilter(
                DummyContent.CHATRECIEVEDNOTIFICATION));
    }
    @Override
    public void onPause() {
        super.onPause();
         unregisterReceiver(receiver);
    }

But getting error on registerReceiver and unregisterReceiver:

All these variables and methods are blongs with activity. So use getActivity() to call these.

Yes, These variables and methods belongs to activity class. So we need to get parent active context to use these in fragment class:

    @Override
    public void onResume() {
        super.onResume();
        getActivity().registerReceiver(receiver, new IntentFilter(
                DummyContent.CHATRECIEVEDNOTIFICATION));
    }
    @Override
    public void onPause() {
        super.onPause();
        getActivity().unregisterReceiver(receiver);
    }
