GeoFence using PendingIntent.getBroadcast() not working

问题

I am trying get a Geofence trigger to a BroadcastReceiver and the BroadcastReceiver has the code to read the data from the intent and act on the data sent in intent. My BroadCastReceiver is GeoLocationBroadCastReceiver. I am invoking this code when my activity is opened and the app is in background.

public PendingIntent getPendingIntent(Context context){
   Intent i = new Intent(context, GeoLocationBroadCastReceiver.class);
   return PendingIntent.getBroadcast(context, 0, i, PendingIntent.FLAG_UPDATE_CURRENT);
}

This PendingIntent is passed to the addGeofences method along with the GeofencingRequest.Builder(this data is returned in the addGeoFence method).

GeofencingClient client = LocationServices.getGeofencingClient(context);
 client.addGeofences(addGeoFence(100, lat, long, true), getPendingIntent(context))
                .addOnSuccessListener(new OnSuccessListener<Void>() {
                    @Override
                    public void onSuccess(Void aVoid) {
                        Log.e(TAG,"Added from location geofence");
                    }
                });

When I invoke the above code the geofence is added successfully.

Receiver declaration in Manifest.xml file:

 <receiver
        android:name=".LocationMagic.GeoLocationBroadCastReceiver"
        android:enabled="true"
        android:exported="true"/>

The problem: I am not getting broadcast and the receiver is not called. I see the google suggested approach is to use the broadcast to overcome the background limitations with services. I know the Broadcast limitations as well(whitelisted and blacklisted). But as per google codelabs the suggested approach is to use broadcast. Google code labs link here.

From google codelabs:

Apps targeting O are further subject to limits on services started in the background. For this reason, apps targeting O should not use PendingIntent.getService() when requesting location updates. Instead, they should use PendingIntent.getBroadcast().
