Android Studio Tutorial : Build Hello World App

As you know Android Studio is official IDE for developing Android apps. A few years back we had eclipse for android development. But Android studio is far better than eclipse. At first glance, the android studio looks so complected but in actual it’s super easy. In this tutorial, we will see an overview of the Android studio and will see how to create a project in the android studio. Here I’m assuming that you have installed all the required stuff. IF not read official documentation. I’m using 2.3.1 version but everything will be same for all the versions.

After launching the project you will see a window like the following image. You just have to click on start new project
