android.view.WindowManager$BadTokenException: Unable to add window -- token android.os.BinderProxy@db81f9c is not valid; is your activity running?

According to the log, it is often due to that it want to display a view (e.g. dialog) on a special page, but now it couldn't find the page (on android ,it's activity).Then it will throw such error log. You can recheck your code.
