I: Done.
Can't find framework resources for package of id: 2. You must install proper framework files, see project website for more info.

and then when trying to recompile i get this:

C:\AndroidApktool>apktool b SecMms
Exception in thread "main" brut.androlib.AndrolibException: brut.directory.PathNotExist: apktool.yml at brut.androlib.Androlib.readMetaFile(Androlib.java:164)

So i moved the apktool.yml to the folder and then I get this:
