Using BroadcastReceiver to pass Intent.EXTRAS

Question

Main Question: Can I use a BroadcastReceiver to pass an intent with extras to an Activity?

Setup: I have a recorded date from a DatePicker fragment and I want to make sure that the Millis time is passed to another activity, but that activity is not immediately called from that Activity that contains that fragment

I tried using the following code in the activity with the datePicker Fragment:

Intent intent = new Intent().putExtra(EVENT_MILLIS, eventDateMillis); 
LocalBroadcastManager.getInstance(this).sendBroadcast(intent);

in the "receiving" activity:

@Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstatnceState);
setContentView...
LocalBroadcastManager.getInstance(this).registerReceiver(mReceiver, new IntentFilter(EVENT_MILLIS));

and my call to initiate the receiver:

private BroadcastReceiver mReceiver = new BroadcastReceiver () {
@Override
public void onReceive(Content content, Intent intent) {
   setReceivedDate(intent.getLongExtra(EVENT_MILLIS,0));
}
}

Using Broadcast is not a good pattern and it looses efficiency of your app. Try using EventBus instead. It's easy to use with lower issues.
