Can I use Robotium if I only have the apk file?

Which version of Android does robotium support? My Android Version is 5.1.1! I get started with Robotium and then enter the Start command, but the screen goes to the Google screen and freezes there. I think I am going to need to wipe the tablet, but if there’s another trick, please advise! I need clear instructions how to proceed because the solutions posted on YouTube are just confusing!
