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 it

Answer 1

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
