Hello,
My application has floating popup window (PopupWindow) that is
successfully displayed on user click.
When screen orientation is changed, everything is recreated and I want
my Popup to remain visible.
onRestoreInstanceState is called and my Popup function crashes whilst
calling "showAtLocation":
View parentView = this.getCurrentFocus();
if(parentView != null) {
mPopup.showAtLocation(parentView, Gravity.BOTTOM, 0, 0);
}
LogCat saying:

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

My assumption is that Main Activity Window is not yet displayed (not
yet created) so can not display popup.
Where can I show this popup then? How do I catch event when activity
is displayed.
I can start popup again in this new session, but I would like it to be
opened on screen orientation change.
