Broadcast reciever not working from service

Question

I am trying to use BroadcastReceiver inside my service but it is not working properly.

I am starting my service in an onCreate in my activity. Then in the services onCreate I am calling the following to register the Broadcast reciever:

    IntentFilter filter = new IntentFilter();
    registerReceiver(DataUpdateReceiver, filter);

Here's the broadcast receiver i am trying to register:

    private BroadcastReceiver DataUpdateReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {

        Toast.makeText(context, "Test", Toast.LENGTH_LONG).show();

    }
};

Then else where in the Activity I am trying to call this so therefor the Toast message will be displayed.

            Intent i = new Intent();
            sendBroadcast(i);

But the Toast is not being displayed, I have also tried logging but nothing shows up. If anyone could help me out on this it would be appreciated, ty.

In my opinion, you have to specify action (or actions), which fire onReceive() method. Something like this might help you:

IntentFilter filter = new IntentFilter("some_action");
registerReceiver(DataUpdateReceiver, filter);

...

Intent i = new Intent("some_action");
sendBroadcast(i);
