Nested android application won't launch

I have an Android application with a main activity called GameOfLifeGameActivity in a package called edu.brandeis.gameoflife.

It extends a class in a different package (and different Eclipse project) called GameActivity in a package called edu.brandeis.minigamee. I am having trouble getting it to launch.

I think it has to do with the cross-package and cross project reference. It never gets to the onCreate. Instead, it looks like during startup of the app, I get this fatal exception (see below.)

Anyone with any idea on what that might mean and how to fix it? Thanks 10^6.

I have never seen a project that uses a class from a separate project. I don't know for a fact that this won't work, I've just never seen it. So I would suggest copying your edu.brandeis.minigamee package into the same project that contains GameOfLifeGameActivity.
