No, the dialog is only accessible in landscape mode. But if the dialog
is open, I want it to stay in landscape mode.

Of course there is, but the dialog does not make much sense in portrait
mode because it also contains text fields. And of course it's additional
work.

I did, but it didn't help (see earlier mail). Of course there are other
possibilities to disable the rotation (like not listening to device
orientation changes), but I thought I'll first try the obvious/official
one.

Thanks for your answer!
