WHAT YOU NEED TO KNOW BEFORE STARTING AN APP DEVELOPMENT?

If you intend to build an app entirely on your own, and not part of a team, here is a short list of what you need to know:

1. Layout and design - whether you use the XML tools, or build it with code, you will need to design. You will need to understand UI best practices.
2. Graphics - You will need to develop assets. You will need screen shots, icons, store icons and previews, graphics for within the app, launch icons, and a slew of other items. All of which need to be designed to the correct specs.
3. Programming - You will need to know at least the basics of programming, no matter which language you use. Variable types, loops, conditional statements, and functions exist in all languages. It’s just a matter of syntax in moving from one to the other. The basics of programming logic are the same no matter what.
4. The ability to navigate the ins and outs of deployment. Whether you are building an entry for the Apple Store or Google Play, you will need to go through a long list of trial and error before you finally get it right. You need to read and understand all the things that are written on those screens.
5. Be aware of what you are building, and make sure that ALL of your assets are yours. Be aware of the laws in other countries. Be aware that children exist. In short, be aware.
6. If you intend to monetize your app, and of course you do, you will need to get yourself an AdSense/AdMob account, and learn all the ins and outs of those systems.
