Ok, RS works.
Your menu is OK, but has a small disadvantage on my HC tablet. To access all options, you must scroll.
Can't realy say which is the better one. I like both versions.
If you find a fix for the hide/unhide bug with the 2 status bars, by pressing the back button, would be great. 
Is it possible, that you create your tests with a different package name ? So we can keep Pauls and you version for better comparison without the need to delete one of them first.
The scrolling is better in my option than one screen loaded with options from top to bottom. It makes it look a little nicer as well. Plus, the preference screen is now actually using the PreferenceActivity and PreferenceScreen classes for android instead of the one Paul has made.
I certainly don't mean that in a bad way though, just that if android's built in versions of the same thing are better in long term than reinventing the wheel so to say. If PreferenceActivity and PreferenceScreen at some point become deprecated, it'll be easier to move over to the new one. Not to mention it also reduces the amount of code that needs to be compiled for just the interface, reducing code size overall. There's still work to be done on it though (hence this test, but you already know this). So overall, this is purely done out of a way to have better code maintainability
Also, about using a different package name, I'll do that from now on
Now, about the two bars that interfere on tablet devices when using the emu, these cannot in any way be hidden, on mobile phone using Android 4.0+ it is possible (from what I've read, correct me if I'm wrong), but there is no method I know of for hiding them on tablets.
