Like iOS App store you can find apps from all categories on Android platform even with cheaper rates. You can easily find the Android app programmer who is creative, talented, skilled and well experienced in the development of various niches mostly in reputed outsourcing companies. Here I prefer outsourcing companies because local Android app programmer is costly while offshore development companies offer excellent services at significant cheaper rates due to currency differences between the countries.
