Changes not reflected after receiving the intent from broadcastreceiver

Question

I am doing adapter.notifyDataSetChanged() and listView.invalidateViews() after I get the receive call if the condition say "blabla" gets true. But still my UI is not getting updated.

public class UserFragment extends Fragment{

public class FragmentReceiver extends BroadcastReceiver {
        @Override
        public void onReceive(Context context, Intent intent) {
            if(getSetting("CurrentView","").equalsIgnoreCase("blabla")){
                adapter.notifyDataSetChanged();
                listView.invalidateViews(); //this is not updating the UI.

}
}

NOTE: I tried to call the same UserFragment.java to update the changes by replacing the same fragment again but that's although updating the UI but giving exceptions- IllegalStateException: Can not perform this action after onSaveInstanceState

My rest of the code in onReceive method -

UserFragment firstFragment = new UserFragment ();
getSupportFragmentManager().beginTransaction()
                    .replace(R.id.headlines_fragment, firstFragment)
                    .addToBackStack(null).commit(); //IllegalStateException: Can not perform this action after onSaveInstanceState

Any ideas?

try this

public class UserFragment extends Fragment{
public class FragmentReceiver extends BroadcastReceiver {
        @Override
        public void onReceive(Context context, Intent intent) {
            if(getSetting("CurrentView","").equalsIgnoreCase("blabla")){
                adapter.notifyDataSetChanged();
                listView.invalidateViews(); //this is not updating the UI.
                UserFragment.this.onCreate(savedInstanceState);

}
}
