local broadcast manager usage

receiver.java

// register the receiver you created and 
// add a filter to only receive the intent you need
LocalBroadcastManager.getInstance(this).registerReceiver(
        		myReceiver, new IntentFilter("location"));

// create your own receiver from BroadcastReceiver class
private BroadcastReceiver myReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        // get the info from the intent we received
        Double test = intent.getDoubleExtra("test", 20);
        Toast.makeText(getBaseContext(), test, Toast.LENGTH_SHORT).show();
    }
};

sender.java

// create an intent to hold your info
Intent intent = new Intent("location");
// put your info into the intent
intent.putExtra("test", 99);
// use LBM to send the intent
LocalBroadcastManager.getInstance(getBaseContext()).sendBroadcast(intent);
