I\'m getting this error when trying to run unit tests from Eclipse with an Android Project. The list of Instrumentation Test Runners is empty in the Android preferences.
The problem is when you created the project, you would have had a AVD, so these configuration would be missing. My suggested way is first create the AVD and then create the android project :).
If you would have already created the project and if does not have much code you have written I would suggest to delete it and create a new one.
