Problem:
You are trying to compile against a stub .jar when using Android Studio. When you compile and run the .apk on your device, you get a RuntimeException telling you to move the .jar to your classpath.
Cause:
You have the .jar set to compile.
Solution:
In Android Studio 0.5.7, go to File -> Project Structure.
Select your module.
Go to the "Dependencies" tab.
Find your stub .jar.
Click the down chevron next to "Compile" and change it to "Provided."
Rebuild.
