Android Robotium NoClassDefFoundError

Question

I was just trying to use Robotium in an Android JUnit Test, but the Testing always fails with an error:

java.lang.NoClassDefFoundError: com.jayway.android.robotium.s

Answer 1

What I did to fix the bug was :

• Remove the libraries from the standard Java build path :
• Right click on the project name > Properties > Java Build Path > tab Libraries > remove everything except the “Android X.X” (2.3.3 in my case) and the “Android Dependencies”
• Rename the libraries folder from “lib” to “libs”
• By doing that, all the libraries in the folder “libs” are found by the Android plugin and are added to the “Android Dependencies” item of the project
• Clean the project (not exactly needed)

You are good to go !
