I've decided it's time to set up proper CI (I've upwards of 9000 unit tests now, [which still run very fast locally]) and integrate it into my GitHub hosted private repo. The project is an Android project (so requires Android SDK etc to run tests).
I originally went with TravisCI and was blown away by the 129/mo they ask for a single private project.
I was wondering what others in the community are using and have found useful for similarly scoped small but not open source Android projects. Must be cheaper than TravisCI.
