Ask HN: Is Android profitable?

I always read iOS success stories on HN and there are lots articles about Android fragmentation, lack of sales on Google Play and game studios which quits Android development due to above circumstances. I want to dive into mobile development and don't want to invest time and money for a platform which is not worth in short and long period. Development for Android is relatively easy. (standart PC with Java is enough for prototyping) But I have doubts about application profitability and making initial pitch.
