I am trying to show an AlertDialog from different thread. I received following crash on firebase: android.view.WindowManager$BadTokenException: Unable to add window -- token android.os.BinderProxy@415924 is not valid; is your activity running?

Tried to check if the context is active or not, but the issue still persists.

if(!((Activity)context).isFinishing()) {
    alertDialog.show();
}

Are you using `WindowManager.addView()`? – Darkman Feb 07 '21 at 15:28
No. I'm using AlertDialog.Builder to build the dialog. Now I'm also checking if the activity is already destroyed or not before showing the dialog. Let's see if that solves the issue. – Md Yeamin Feb 07 '21 at 15:45
`from different thread.` Don't tell me that you're showing the dialog in a background thread?. – Darkman Feb 07 '21 at 15:58
No. I am showing dialog in UI thread. – Md Yeamin Feb 08 '21 at 02:47
