Careful with that train of thought. Iphone can be profitable but there's a big emphasis on quality and app approval. Google sucks. It pays the bills atm but they all want something for nothing. I managed to put up 6 paid apps, driven by self hosted ads on free apps that gett traffic.

I tried what other devs did first, making free apps with adrev. Waste of time unless you get featured or you're really patient.

I can't believe somebody knocked java. You can do it with your eyes closed! Would you rather code windows apps and debug memory leaks and other frustrating shit? I like quick coding andgarbage collection.

Mobile is already oversaturated as fuck. Unless you plan on spending months of time maturing an app, dealing with constant phone incompatibilities and continuous assault from new competing apps, id recommend coding a game in unity and exporting to all platforms with a focus on in app purchase.

I pave my own way I'm nott making this shit up
