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.solo.Solo

thrown at solo = new Solo(getInstrumentation(), getActivity()); in the setUp() method:

protected void setUp() throws Exception {
    super.setUp();
    solo = new Solo(getInstrumentation(), getActivity());
}

I read somewhere that this could be related to the Android SDK revision 17, but I cannot confirm this, as I first tried Robotium already with SDK 17.

The Robotium jar is properly added to the project build path.

Has anyone encountered similar problems?

Regards
K.

I had the same problem today. I solved by importing the jar into the libs directory of the test project and then adding it to the Build Path Libraries:

TestProject Properties -> Java Build Path -> Libreries -> Add JARs… -> TestProject/libs/robotium-solo-3.1.jar
