broadcast receiver not receiving intent from service

Question

I have searched SO and even found a question with more or less the same title as my question. But still my code isn't working.

I try to send a position from my GPS service to my MainActivity using broadcast.

In my GPS service I do

Intent intent = new Intent(MainActivity.EXTRA_NEW_POS_FOR_PLOTTING_INTENT);
            intent.putExtra(MainActivity.EXTRA_NEW_POS_FOR_PLOTTING, new LatLng(location.getLatitude(), location.getLongitude()));
            LocalBroadcastManager.getInstance(this).sendBroadcast(intent);

On the receiving side in MainActivity.onCreate() i do:

mBroadcastReceiver = new BroadcastReceiver() {
            @Override
            public void onReceive(Context context, Intent intent) {
                LatLng pos = intent.getExtras().getParcelable(EXTRA_NEW_POS_FOR_PLOTTING);
                newLocForPlotting(pos);
            }
        };

And in MainActivity.onStart() I have:

LocalBroadcastManager.getInstance(this).registerReceiver(mBroadcastReceiver, new IntentFilter(EXTRA_NEW_POS_FOR_PLOTTING_INTENT ));

I know that my service calls sendBroadcast(), but my onReceive() is never called.

What is going wrong?

Answer 1

put this code into your activity onResume method.

LocalBroadcastManager.getInstance(this).registerReceiver(mBroadcastReceiver, new IntentFilter(EXTRA_NEW_POS_FOR_PLOTTING_INTENT ));

You can also use Local broadcast like this

Intent intent = new Intent(BundleTags.BROADCAST_TAG_FOR_INCOMING_CALL_REQUEST);
            // You can also include some extra data.
            intent.putExtra(RESPONSE_MESSAGE, body);

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

In activity

 LocalBroadcastManager.getInstance(ServiceProviderActivity.this).registerReceiver(myReceiver,
                new IntentFilter(BROADCAST_TAG_FOR_INCOMING_CALL_REQUEST));
