Android

I started learning Android through YouTube tutorials. It took me almost a year (being an IT student) to create a decent app for Play Store, you can take more or less time depending on your learning capabilities and the amount of time you put into learning on daily basis. You don't need to know everything about Android Studio and Java to create Android Applications. Just watch some tutorials, start playing around with Android Studio, create some sample projects, and start with text views, buttons and you'll begin to understand what's happening with the code. This is the way I learned it. Honestly, I don't know complete android, I learnt like 1 or 2% from those YouTube tutorials but still I am able to create some applications. I have uploaded like 5 of them on Play Store, where one of them received 50k+ installs within 2 years of release. So, start learning and practicing without worrying about the time consumption, it's always fun to code and the feeling of being able to create apps for others to use is just awesome.
