[Android Software/Hacking General [Developers Only]] gdrocks:
So i'm trying to theme a google+ app for personal use, and I want to edit the XML files to get a full change out of it. The problem is that it force closes when I try to run the app on my phone (no problems decomp or compiling with apk manager or apktool)

The logcat (can't add links yet, in code tag below) points to a FATAL EXCEPTION in main, and goes on to state:

"Caused by: java.lang.RuntimeException: Binary XML file line #4: You must supply a layout_width attribute."

Of course I can't find anything labeled "main" and there I don't know which XML file to edit, and do not see anything wrong in the layout XML files (again, I haven't edited the files at all, it's simply decompiling an untouched app then compiling and installing to a phone and emulator - both resulting in a FC of the app)

Png editing is of course no issue, but it's not quite giving the effect I want (black on forest green is tough to read)

Any assistance or perhaps a nudge in the right direction so I can figure this out and start theming apps?
