passing bundle from service to receiver return null

passing bundle from service to receiver return null

i want to pass data in bundle from service to receiver to change ui data instantly

i have pass data bundle as hashmap key and get the same in activity class but always get null i just register registerReceiver in code not in manifest

main activity 

BroadcastReceiver receiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            try {
                if (intent != null) {

                    Bundle extras = intent.getBundleExtra("hashmap");
                    Toast.makeText(context, extras + "  " + intent.getBundleExtra("hashmap"), Toast.LENGTH_SHORT).show();


                }

            } catch (Exception e) {
                e.printStackTrace();
            }

        }
    };


    @Override

    protected void onResume() {
        super.onResume();
        try {
            LocalBroadcastManager.getInstance(this).registerReceiver(receiver, new IntentFilter(FIRMessagingService.REQUEST_ACCEPT));
        } catch (Exception e) {
            e.printStackTrace();

        }
       /* try {
            registerReceiver(receiver, new IntentFilter(FCMActivity.NEW_NOTIFICATION));
        } catch (Exception e) {
            e.printStackTrace();
        }*/
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        try {
            LocalBroadcastManager.getInstance(this).unregisterReceiver(receiver);


        } catch (Exception e) {

        }
        /*try {
            unregisterReceiver(receiver);
        } catch (Exception e) {
            e.printStackTrace();
        }*/
    }

service(Firebase)

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    super.onMessageReceived(remoteMessage);
    Log.e("Msg", remoteMessage.getData().size() + "");
    //sendNotification(remoteMessage.getData());
    try {
        LocalBroadcastManager broadcaster = LocalBroadcastManager.getInstance(getBaseContext());
        HashMap<String, String> data = new HashMap<>();
        Bundle msg = new Bundle();
        for (String key : data.keySet()) {
            Log.e(key, data.get(key));
            msg.putString(key, data.get(key));
        }

        Intent intent = new Intent(REQUEST_ACCEPT);
        intent.setAction(REQUEST_ACCEPT);
        intent.putExtra("hashmap", msg);

        broadcaster.sendBroadcast(intent);


    } catch (Exception e) {
        Log.e("error" + "receiver", e.toString());
    }

Map<String, String> data = remoteMessage.getData();


    Bundle msg = new Bundle();
    for (String key : data.keySet()) {
        Log.e(key, data.get(key));
        msg.putString(key, data.get(key));
    }

its because u have just initialised it.but never pass data to the map object. so map is always null . try below code

 Map<String, String> data = remoteMessage.getData();


        Bundle msg = new Bundle();
        for (String key : data.keySet()) {
            Log.e(key, data.get(key));
            msg.putString(key, data.get(key));
        }

Try extra.getString(key) with some of the keys you added in onMessageReceived (wich should be saved in R.strings) instead of intent.getBundleExtras("hashmap")

That is because your HashMap data is empty. You are creating a new object of HasMap and trying to get value from it which is actually empty.

HashMap<String, String> data = new HashMap<>();
