IllegalStateException: this action cannot be performed after onSaveInstanceState in the FragmentActivity class

Question

This is the code I wrote .i could not find when this functionality crashes, but it works sometimes.

public class ListFragmentActivity extends FragmentActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); main(); IntentFilter filter1 = new IntentFilter("com.venkat.listfragment"); registerReceiver(myReceiver, filter1); // register reciever intent filter. } public void main(){ IntentFilter filter1 = new IntentFilter("com.venkat.listfragment"); registerReceiver(myReceiver, filter1); List_Fragment ls_fragment = new List_Fragment(); getSupportFragmentManager().popBackStack(null, FragmentManager.POP_BACK_STACK_INCLUSIVE); getSupportFragmentManager().beginTransaction() .replace(android.R.id.content, ls_fragment).addToBackStack(null).commitAllowingStateLoss(); } @Override protected void onSaveInstanceState(Bundle outState) { } private BroadcastReceiver myReceiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { main(); } };} 

I have four tabs. When I click on one tab, it displays the corresponding screen from this screen as well. I am moving another screen with the same tab. But to return to the previous screen, when I clicked on the same tab, I have a broadcast receiver recorded for this.

I get this error:

I have mentioned so many links related to this problem, but this does not fix my problem.

Registering BroadcastReceiver in onResume() and unregistering in onPause() will solve the problem. If necessary, you can use onStart() / onStop() .
