Android Showdialog : Illegalstateexception: Can Not Perform This Action After Onsaveinstancestate

In runOnUiThread() of an Activity, I'm trying to show a ProgressDialog. FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction(); ProgressDialogFr

Solution 1:

@OverrideprotectedvoidonSaveInstanceState(Bundle outState) {
    //No call for super(). Bug on API Level > 11.
}

don't make the call to super() on the saveInstanceState method. This was messing things up...

After some more research, this is a know bug in the support package.

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

@OverrideprotectedvoidonSaveInstanceState(Bundle outState) {
    outState.putString("WORKAROUND_FOR_BUG_19917_KEY", "WORKAROUND_FOR_BUG_19917_VALUE");
    super.onSaveInstanceState(outState);
}

In the end the proper solution was (as seen in the comments) to use :

transaction.commitAllowingStateLoss();

when adding or performing the FragmentTransaction that was causing the Exception.

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 Updated : For showing the DialogFragment using stateLoss use the following lines.

DialogFragmentloadingDialog= createDialog();
FragmentTransactiontransaction= getSupportFragmentManager().beginTransaction();
                    transaction.add(loadingDialog, "loading");
                    transaction.commitAllowingStateLoss();
