In this Android Studio Hello World Example we demonstrate how to create your very first Android app. The app is super simple and prints “Hello World” to the screen. After showing you how to create app, we explain what each component does so that you can get a better understanding of the file structure for Android projects when using Android Studio since it’s different than structures used by other IDEs (e.g. Eclipse).
Before you begin, I highly recommend you download the Android Studio Hello World app from Google Play to see how it looks when you’re done.
