Weird, I know we have Robotium and Robolectric working fine in Android Studio at work. Although some versions do require a separate project, most versions are just sub-projects under a main folder with a shared build.gradle now. Not than any of us want to use it. You are just forced to if you want to use the latest features like AARs with Gradle. Eclipse is unfortunately obsolete and incapable of handling the latest stuff, even though we all used it for years and prefer it.
