Broadcast reciever not working from service

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.

Declare on top of the class 

public final static String MY_RECEIVER_START = "com.yourcompanyname.appname.MY_RECEIVER_START";

private Radio radio;

In the service constructor

    //Initiate our receiver
    radio = new Radio();

    //Activate our recevier
    context.registerReceiver(radio, new IntentFilter(MY_RECEIVER_START));

Also in the service, create the receiver class and the method which shows toast

/**
 * Receiver Class
 * This setup checks for the incoming intent action to be able to
 * attach more messages to one receiver.
 */
private class Radio extends BroadcastReceiver{

    @Override
    public void onReceive(Context context, Intent intent) {

        if (intent.getAction().equals(MY_RECEIVER_START)){
            //show toast


        }

    }
}

After from anywhere in the application send message to our radio

context.sendBroadcast(new Intent("com.yourcompanyname.appname.MY_RECEIVER_START"));

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);
