Description

This is caused because a the fragment manager cannot display a dialog after onSaveInstanceState().

This bug can be triggered by loading a webpage like www.libreoffice.org that has a delayed download and then switching to a different app before the download starts. It has also been reported that this can happen with SSL certificate errors.

I am a little puzzled as to why this is happening, as the WebViews are paused when onSaveInstanceState() is called.

It looks like certain aspects of the processing of website, like the processing of certificate errors or downloads, continue even when a WebView is paused. Because a dialog cannot be displayed when the app is not in the foreground, the most obvious solution is to wrap the display of these dialogs in `try`.

The only downside is that they don't be displayed at all, even when the user returns to the screen.

It turns out it is possible to use a while loop to wait for the window to become active before displaying the dialog.
