BroadcastReceiver with multiple filters or multiple BroadcastReceivers?

instead, you may provide two different intent filters:

filter for refresh only

IntentFilter filterRefresh = new IntentFilter(Params.INTENT_REFRESH);

filter for refresh and update

IntentFilter filterRefreshUpdate = new IntentFilter();
filterRefreshUpdate.addAction(Params.INTENT_REFRESH);
filterRefreshUpdate.addAction(Params.INTENT_UPDATE);

now you may switch between intent filters by registering and un-registering the desired one but your receiver's implementation would be same

For every action , create IntentFilter and register it.

@Override
protected void onResume() {

    super.onResume();

    BroadcastListener receiver = new BroadcastListener();

    // Register the filter for listening broadcast.
    IntentFilter filterRefresh = new IntentFilter(Params.INTENT_REFRESH);
    IntentFilter filterUpdate = new IntentFilter(Params.INTENT_UPDATE);

    registerReceiver(receiver, filterRefresh);
    registerReceiver(receiver, filterUpdate);
} 



private class BroadcastListener extends BroadcastReceiver {
    public void onReceive(Context ctx, Intent intent) {

        if (intent.getAction().equals(Params.INTENT_UPDATE)) {
            update();
        } else if(intent.getAction().equals(Params.INTENT_REFRESH)) {
            refresh();
        }
    }

}

Using KOTLIN you can do it inline:

  broadcastReceiver = NukeBroadcastReceiver()
        registerReceiver(broadcastReceiver, IntentFilter().apply {
            addAction(ACTION_DESTROY_EVERYTHING)
            addAction(ACTION_RESTART_WORLD)
        })
