What is the future of android developer and (Vs) iphone developer?

I have completed my b.e. In computer science. I want to know is there any scope for android development or iphone development, if i do a course in it? Currently I don't have job but i'm seeking for one.So, if there's good future in this, i'm thinking to go for it. I'm asking for this in such a manner that, say today in market, there are no openings for software tester.So, its not worth of doing Software Testing course.

Please, Hoping Suggestions.
