LocalBroadcastManager onReceive() not called

Question

This is what I'm doing :

I'm sending an intent from MainActvity to my Fragment using LocalBroadcastManager. I wrote the onReceive() code in onCreateView() of the Fragment class. I'm unregistering the Receiver in onDestroy().

But onReceive() is not getting called. Why?

In MainActivity class :

   void handleText()
{ 
          Intent i = new Intent("receiveURL");
          i.putExtra("key", sharedText);

          this.sendBroadcast(i);
}

In my Fragment class :

public class AddTab extends Fragment implements View.OnClickListener {

    BroadcastReceiver  receiver;

    EditText textBox;

        @Override
    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {

        // Inflate the layout for this fragment
        view = inflater.inflate(R.layout.fragment_add, container, false);

        textBox = (EditText) view.findViewById(R.id.editText);

        receiver = new BroadcastReceiver() {
//This is not getting called
            @Override
            public void onReceive(Context context, Intent intent) {
                String g = intent.getStringExtra("key");
                textBox = (EditText) getView().findViewById(R.id.editText);
                if (textBox != null){
                    textBox.setText(g);}
                else{
                    Log.d("NULL", "");
                }

                Log.d("received","");
                }
            };

      LocalBroadcastManager.getInstance(getActivity()).registerReceiver(receiver, new IntentFilter("receiveURL"));
...
//some code
    }


    public void onDestroy() {


         super.onDestroy();
         LocalBroadcastManager.getInstance(getActivity()).unregisterReceiver(receiver);
    }

}

Why is that receiver is not getting called? Any help please?

Answer 1

You are using this.sendBroadcast(i) which sends a global, inter-app broadcast that will not be received by a LocalBroadcastManager.

In your MainActivity, replace

this.sendBroadcast(i);

with

LocalBroadcastManager.getInstance(this).sendBroadcast(i);

This will work.
