Android Studio Installation

Why Android development?

There are over 1 billion Android devices active and 2.2 million android apps on Play Store today. Android represents an incredible opportunity for developers. Android applications can be developed both in Android Studio and Eclipse, which are both IDEs. However, Android Studio is the official IDE for app development by Google, so it is highly recommended to use Android Studio for development.

Quick Overview

An android app is written in XML for the frontend UI and JAVA for the backend.

All the backend part is done using Java. But now, Kotlin Language is declared for Official by Google for Android development.Although it’s not a big deal to switch to Kotlin as If you know any object oriented programming language, then it will not be much difficult to relate to the concepts used during development. In short if you know C++ then also you are at peace.

The frontend part is done using XML. All user interface elements in an Android app are built using View and ViewGroup objects.
