IllegalStateException: Can not perform this action after onSaveInstanceState in FragmentActivity class

Question

This is the code which i have written.i could not able to 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 and from that screen i am navigating another screen with in the same tab.but to get back to the previous screen when i clicked on same tab i have written a broadcast receiver for that.

i am getting this error:

I referred so many links related to this issue but those are not resolve my problem.

I think this is tied to these kind of problems reported and discussed in [this SO question](http://stackoverflow.com/q/7469082/1051783). — gunar, Sep 23 '13 at 10:41

Registering BroadcastReceiver in onResume() and unregistering in onPause() will solve the issue. If needed, you can use onStart() / onStop() as well.
