LocalBroadcastReceiver doesn't work from inside a thread

I am building a simple chat application. When I receive a message, I sent a broadcast message.

As this is run inside a thread started by a service, I pass the context to the thread. MyConnection is a class extending thread.

@Override
public void onCreate() {
    super.onCreate();       
    connection = new MyConnection(getApplicationContext());
}

So inside the thread when I receive a message, I do this...

Intent i = new Intent();
i.putExtra("from", message.getFrom());
i.putExtra("message", message.getBody());
i.setAction(MyService.MESSAGE_RECEIVED);                
_context.sendBroadcast(i);

_context is the getApplicationContext() I passed to the constructor of the thread. I have the receiver registered in my Manifest file.

So this is all working and my receiver receives the message successfully.

Now I want to change this to use the LocalBroadcastManager. So what I did was simply change the _context.sendBroadcast(i) to

LocalBroadcastManager.getInstance(_context).sendBroadcast(i);

However my BroadcastReceiver is not receiving any of the broadcasts sent this way.

What am I doing wrong? Do I need to register the receiver in a different way in Manifest to receive local broadcasts? Are there any other steps required to make it work?

Did you register your broadcast receiver with registerReceiver or in manifest?

Instead of passing getApplicationContext() pass this, because Service extends Context, too.
