One could also try with Helium (previously "Carbon"), which does not require root. It runs with Android 4.0+. I think it uses those adb commands under the hood, but is much easier to use. It's primarily a backup tool, but it can also be used to transfer apps (with data) between devices.

I didn't try it myself, but if someone wants to transfer his game and has at least Android 4, he could give it a try.

Also, if you have an older phone (Gingerbread) and want to replace it with a new one, you should try to root the old device and backup your game before having to restart from nothing on your new phone.
