OK, first time I have tried the second section. (and by the way, "4.8" still says it 4.7. Weird). Anyway, I can DECOMPILE an APK just fine, but when I try to COMPILE it, it wont do it. Keeps giving me an error, and says to check the log file, which I still dont know how to make sense of. Any ideas?
More then likely you need to set the environment PATH. I had this issue with apktool.jar not finding the path for aapt.exe.
