Hello there, i've a PreferenceActivity which works perfectly the first time i launch it.

But if i close it ( with the back button ) and then i re open it ( through a menu click in the main activity ) then i get a black screen. There is no preferences at all..

I can't figure it out why it should not working.

It seems all the code is being called normally as the working one but no preferences are showing on the screen.

Did someone had the same behaviour ?
