I run a "pure" stock root (i.e. adb). The past few days I've been learning a lot about editing and applying themes, mainly through the framework-res.apk images, etc. (thanks to 928droid, who's latest MM theme is very slick) I want to learn more about how the xml files tie into the theming b/c I'd like to be able to basically do with my phone exactly what I want (I don't expect any of my stuff to be interesting enough to share ), like something as small as adding a different image to the status drop down background. But for the life of me I can't open any of the existing xml files in any of the xml editors I've tried - I get error messages every time. So, my two questions: What am I missing on opening the xml files? Do they need to be edited another way? I'm sure it's something stupid, but like I said, still learning... Do I even need to mess with the xml files, or do all of you who create themes just edit the image files and not mess with the xml? Thanks!
