Dialog disappearance error

[Chou95]

Creating a bug report/issue

Hi, dear developers!
I am using your app Webmon! I like the app but I find that some dialogs may disappear when I rotate the phone.

Do you think that these errors could be fixed? For example, by saving the return value of dialog.isShowing() in onPause(), the UI state of the dialog could be saved. So as the other contents in the dialog. For example, the previous input can also be saved through saving the text of the editable widget. In this way, you can restore the UI state the same as before I rotate the phone. In this way, user experience could be improved, right?
