You can create a BroadcastReceiver inside an activity. Register it in onResume() and unregister it in onPause(). Whenever your other receiver receives a broadcast, send a broadcast to this receiver too. If the activity is running(i.e. on front), the broadcast will be received. Do whatever you want in its onReceive().

Example:

BroadcastReceiver br = new BroadcastReceiver() {

        @Override
        public void onReceive(Context context, Intent intent) {
            //Do stuff
        }
    };

Also override methods:

@Override
protected void onPause() {
    super.onPause();
    unregisterReceiver(br);
}

@Override
protected void onResume() {
    super.onResume();
    registerReceiver(br, new IntentFilter("intent_filter"));//Use any string for IntentFilter you like
}

You can update fragments from activiy by creating methods inside fragment and access them from Fragment object inside activity.
