getting exception "IllegalStateException: Can not perform this action after onSaveInstanceState"

Question

I have a Live Android application, and from market i have received following stack trace and i have no idea why its happening as its not happening in application code but its getting caused by some or the other event from the application (assumption) I am not using Fragments, still there is a reference of FragmentManager. If any body can throw some light on some hidden facts to avoid this type of issue: ``` java.lang.IllegalStateException: Can not perform this action after onSaveInstanceState at android.app.FragmentManagerImpl.checkStateLoss(FragmentManager.java:1109) at android.app.FragmentManagerImpl.popBackStackImmediate(FragmentManager.java:399) at android.app.Activity.onBackPressed(Activity.java:2066) at android.app.Activity.onKeyDown(Activity.java:1962) at android.view.KeyEvent.dispatch(KeyEvent.java:2482) at android.app.Activity.dispatchKeyEvent(Activity.java:2274) at com.android.internal.policy.impl.PhoneWindow$DecorView.dispatchKeyEvent(PhoneWindow.java:1668) at android.view.…

Accepted Answer

This is the most stupid bug I have encountered so far. I had a `Fragment` application working perfectly for API < 11, and `Force Closing` on API > 11.

I really couldn't figure out what they changed inside the `Activity` lifecycle in the call to `saveInstance`, but I here is how I solved this :

```
@Override
protected void onSaveInstanceState(Bundle outState) {
    //No call for super(). Bug on API Level > 11.
}
```

I just do not make the call to `.super()` and everything works great. I hope this will save you some time.

EDIT: after some more research, this is a known bug in the support package.

If you need to save the instance, and add something to your `outState` `Bundle` you can use the following :

```
@Override
protected void onSaveInstanceState(Bundle outState) {
    outState.putString("WORKAROUND_FOR_BUG_19917_KEY", "WORKAROUND_FOR_BUG_19917_VALUE");
    super.onSaveInstanceState(outState);
}
```

EDIT2: this may also occur if you are trying to perform a transaction after your `Activity` is gone in background. To avoid this you should use `commitAllowingStateLoss()`

EDIT3: The above solutions were fixing issues in the early support.v4 libraries from what I can remember. But if you still have issues with this you MUST also read @AlexLockwood 's blog : Fragment Transactions & Activity State Loss

Summary from the blog post (but I strongly recommend you to read it) :

- NEVER `commit()` transactions after `onPause()` on pre-Honeycomb, and `onStop()` on post-Honeycomb

- Be careful when committing transactions inside `Activity` lifecycle methods. Use `onCreate()`, `onResumeFragments()` and `onPostResume()`

- Avoid performing transactions inside asynchronous callback methods

- Use `commitAllowingStateLoss()` only as a last resort
