View not attached to window manager (whats the solution?)

Question

I got hundreads of error reports from my app and all of them is the same. It is really annoying because in my test devices (HTC Wildfire, Galaxy S I-II-III, Galaxy Mini, Galaxy Tab 10) this error NEVER occured, neither to me or my test buddy, looks like users do something different then us.

Because of this i cant give you too much information about the situation, there is one thing i see, it is something with a dialog's dismiss, which i actually never calls by code.

here is the error:

java.lang.IllegalArgumentException: View not attached to window manager

Can somebody help me? I got 30-40 error reports weekly because of this issue and i really cannot figure out why this is happening.

All suggestions will be appreciated. Thanks,

Solution 1

Dismiss the dialog in your onFinish or onDestroy of the launching activity.

Or/And

Don't let your activity handle the orientation changes.

You might find some help in these answers : java.lang.IllegalArgumentException: View not attached to window manager

Solution 2

 @Override
            public void onConfigurationChanged(Configuration newConfig) {
                // TODO Auto-generated method stub
                super.onConfigurationChanged(newConfig);
                YourProgressDialog.dismiss();
            }

and Similarly you can use it on the onFinsh() and OnDestroy() or OnBackPressed() of the activity Depending on the Context of error.
