Others have pointed out that you're highly unlikely to make $60k a year off of an Android app. When I first read your question, I was going to write the same thing. But, now I read it again and I wonder if you mean: 1.) Get them certified in Java. 2.) Get them to build an app and put it in the store as a portfolio piece. 3.) Get them to apply for entry level full-time Java jobs. If that's the case, I think it could work. My only concern though is that being an entry level developer is freakishly hard. I wonder how much mental capacity they'll have left to study if they've just spent a day debugging something crazy.
