In a hackathon, my team decided to work on a Android app as a challenge to ourselves. It was our first Android app development and we were very excited at first. But after awhile, one of my teammate (the usual problematic one) gives up implementing the recyclerview after few hours of struggling, and decided to 'fk it' and watch YouTube linustech. As such, I have to takeover and implemented it within an hour by just googling and following some tutsplus tutorial. What do you do with this kind of teammate?
