This is because Guy used the ProGuard for this APK. You can not do reverse engineering after that easily.

Question
I tried to decode a published application from Google Play with its apk file by using dex2jar and apktool.
I successfully manage to get its source code however, I am wondering why the hell I got this sets of codes(attached image)? I could not clearly get the package/s and the activity names of this app. I need it badly.
Is it because of encapsulation? How can I get the real code?
