Passing data from Activity to Fragment?

Question

Android

Greetings!
Got a Question!
Now I sit and understand someone else's code, and rewrite it. There is a problem It is necessary to update the list in the fragment when push notification arrives (pull the function). Now I am passing the given to MainActivity from push by means

Intent intent = new Intent(this, MainActivity.class);

I accept in MainActivity

public void onNewIntent(Intent intent)
    {
        
    }

And then a stupor.
Fragments are attached to the activity using implements, and there is no way to find them by ID.
Question how to be?

Answer 1

And what prevents you from creating a broadcast receiver in a fragment?
