Introduction to Android Studio IDE

Android Studio is the official Integrated Development Environment (IDE) for Android application development, based on IntelliJ IDEA .

Before starting with Android Apps development, Let’s take a tour of Android Studio IDE which required in your whole Android Developer Journey.

Structure of your Project

Above Image shows Android Project View where you will have all your files related to your project. Here, we have one module Android Application which consists of Manifest, Java, Res Folders.

Manifest Folder: This folder consists of a manifest.xml file which android system requires for all the essential information of the application, like:

  • Package Name — Unique Identifier of the application
  • Components — We have to describe all the components in the application (We will discuss components in upcoming chapters)
  • Permissions — Describe all permission application will require
<manifest        xmlns:android=""
<uses-permission android:name="android.permission.INTERNET" />

        <activity android:name=".MainActivity">
                <action     android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />


Java Folder: Here you will have all your Java and Kotlin files.
