This discussion is unlike other threads which starts before making the journey. I am already in the android app stores and successful at it. I was late to the party and still rue the fact that had I been there earlier, I would have made some really serious money. I am on the Google Play store since early 2013 and it has been an exhilarating roller coaster ride. I am a trained computer science graduate and learnt java in 2000 or may be 2001 as part of my college course. I stopped programming in Java some time in 2003. In 2012, I came across a blog (have lost the bookmarks and the link) where some one kept a running commentary about his venture in to the world of apps. That blog, acted as a catalyst and I seriously, started thinking about creating apps. Before that, I bought an Android phone and tablet in late 2010 and started tinkering with roms etc and was thinking about learning how to make Android apps, but never got around to it. In January 2011 I bought a really crappy book that put me off of Android development for two years (I do not recommend Head First into Android book, it sucks balls). Cut to 2013, I tried again, only this time, I started with brushing my Java skills, since the language has evolved quite a lot in the last 12 or so years. It took me about 2 weeks to get up to speed and 2 or 3 more weeks to get my teeth sharpened on Android development. By March 2013, I was ready and raring to go. I uploaded my first app, than one more, and than another. I did not marketing whatsoever and the apps were free with admob ads in them. The first day I earned $2.01, than $1.8 or something, than admob said, they don't like my app because it has girls with bikinis on them. According to the prudes at Google/Admob, babies are delivered by storks and daddy does nothing with mommy. Any way, I quickly found out that sex sells (surprise?) and there are many ad companies who are happy to put their ads on anything that runs on an Android phone. I signed up with Airpush, StartApp and few other companies. And started creating apps with risque videos from youtube and other adult themed apps. While I was busy in the d1ck raising journey to riches, I came across 2D game engines such as LibGDX and AndEngine and fell in love with the. It took me about 2 to 3 weeks and I released my first game. Now it has been 3 month and I was making any where from $300 to $800 per day with my apps. Yes, you read it right. One day I crossed $1000 per day and all my apps got banned in the evening. Google has started cleaning it's house. But I had already tasted blood and started again with increased fervor. They kept banning after a month or two and I kept making more. This continued till September 2013 but stretched to November 2013. Google changed the rules and it was no longer profitable making crash and burn adult apps. Since I diversified with non adult apps, I was able to bear the hit and was able to continue with severe cut in my earnings. I learned my lesson and am going strong again.
