You question is similar to this:

How to write test cases for the home screen activity using robotium in android

Is there a reason you have to automate the lock screen?

Robotium is really build to test one package and not span multiple packages and activities in the same test suite.
You should easily be able to launch you app and test it with robotium, if you can live without automating the lock screen.
