# Prerequisites

Before you begin building the application, you must have the following prerequisite installed on your system:

#### Android Studio

Android Studio is the official IDE for Android application development, as recognized by Google. We will create a project in Android Studio and code the app. The Android project and the IDE must meet these minimum supported environments:

* Android Studio- 3.1.1 or later
* Minimum SDK - API 26: Android 5.0 (Lollipop) 
* Language : Kotlin DSL 
* Gradle- 3.4.0

You can [download the latest version of Android Studio](https://developer.android.com/studio) for your environment and [install it](https://developer.android.com/studio/install), if you don't have it installed on your system. You need not perform any additional configurations to set up your workspace for this app.
