On Rotation I get "Unable to destroy activity ... Can not perform this action after onSaveInstanceState"

Hi and thank you for any help.

I am only at the very beginning of configuring my code to handle rotation: I have implemented onDestroy(), but not yet any onSaveInstanceState() or onRetainNonConfigurationInstance() because I am figuring out what will not cause problems if destroyed and recreated after rotation and what needs to be saved.

In my application I use a Service that runs an AsyncTask, and 3 fragments that get swapped on user pressing buttons.

I use the compatibility library for managing the fragments.

I suspect the error I encounter is related to the fragments;

To be specific, I would prefer the fragments to be destroyed and recreated on rotation, rather that preserving them (because it is my hope that this would make my code simpler...)

when I rotate the emulator I get the error in the title.

This is the code of the main activity:

public class Quotes extends FragmentActivity {

    private String url2;
    //public String responseBody;
    public static ArrayList<Stock> lt;

Can you shift your troubling code to onConfigurationChanged()Burnett
I mean to say if it is not alllowing you to pop back fragments in OnDestroy then write that code in onConfigurationChanged Method, this will be called on orientation changeBurnett
@ChangdeoJadhav no success. thanks anyway!Inesita

Thanks for your info. Meanwhile, I fixed this issue.

What was causing the problem was a Service that needed to be unbound when the Activty was destroyed because of rotation.

As far as I could understand the Fragments are not destroyed when the activity is destroyed. However, I would appreciate any comment on this.

So, I reinitialized the Fragments on the onCreate() method when the Activty is created again after destruction, and this is not causing trouble to the application.

protected void onDestroy() {
   mService.stop();
   stopService(new Intent(this, LocalService.class));
   unbindService(mConnection);
   g.fermaGrab();
   stopService(intent);
   Log.e("ondestroy","passostopService(intent)"); 
   super.onDestroy();       
}

Just because the other answers to this question led me on a wild goose hunt of WeakReferences, memory leaks, and onResumeFragments... you can get this error simply by having an onFocusChangeListener that tries to pop up a dialog box when a control loses focus. The error comes in ActivityThread.handleRelaunchActivity so it's a little tough to figure out.

This just helped me solve a bug when launching my app on an Android 7.1 tablet, I don't know why it was made like this but I added a version check and it just works now: if (VERSION.SDK_INT >= Build.VERSION_CODES.O) then setOnFocusChangeListenerLed
Actually I'm testing and it also happens in 8 and 8.1, in Android 9 (Build.VERSION_CODES.P) it is fixedLed
Nice job StackOverflow, keeping this answer around for ten years just so it could help its first person! I wonder if there's an achievement for that. Glad it worked for you.Perjured
