Hey Xav, I also get the Missing Theme error, I have a very very fresh Eclipse and SDK r9 install (very very fresh because I just got this PC).
I notice that this appears most often when I create a new layout XML file by doing this: - right click on existing layout file - select copy - right click on /layout folder - select paste then edit the filename - try to open the newly created file I have tried the workaround above by selecting an OS version from the rightmost dropdown and the GUI loads up. But the next time I open the file the Missing Theme error happens again. Thanks, Zarah.
