What is the future for Android developers?
Android is growing rapidly, so there is always going to be a need for android developers.
The entry barrier to learn how to make an android app is low these days. However, if you want to find a good job as an android developer, you will need to have a deep understand of programming and android programming than just making a basic android app.
The benefits of android development is that you can make money on the side, such as develop your own apps or games and publish it in the play store. If your app solves a problem for others, they will download your app and even pay for your apps.
I developed a music player app for android half year ago, and it is bring me about $12-$15 per day these days. If the app continues to grow, I can make passive income from it.
So whatever you do, if you have time, I suggest you just go for it and learn it. Don’t spend too much time analyzing because when you spend too much time thinking about a thing, you will never get it done.
