This document provides an introduction to mobile app development, emphasizing the need for programming languages like Java, C#, and HTML. It outlines minimum requirements for PCs and the software environment necessary for building applications, including specific Integrated Development Environments (IDEs) for Android, iOS, and Windows Phone. Additionally, it discusses cross-platform development options using tools like Xamarin and Visual Studio.

1. Mobile App Development
An
Introduction

2. Programming Language
• To develop apps, knowledge of programming
language is mandatory.
• Popular languages like Java, C#, HTML, etc. are
used to program apps for smart phones.

environment.
• First, you need to download JDK ( the java
development kit ). It is the primary kit required.
• Now depending on the platform you want to
develop apps for, your requirement varies.
• We need an IDE.
• An IDE is Integrated Development Environment
that enables you to write, update, view, test,
debug and deploy your application.

5. For Android Apps
• To develop Android apps, you need an IDE called
Android Studio or Eclipse IDE.
• Both of them are popular and widely used.
• Download anyone of them and install it.
• The installation is simple and may take up to 2 hours.
• After the installation is complete, you need to
download SDKs.
• SDKs are Standard Development Kits. After all this, you
are ready to start building your apps.
• Language used is Java.

6. For IOS Apps
• To develop IOS apps, you need an IDE called X-
Code.
• Popular and widely used IDE by Apple Inc.
• To download it, you require a Mac and an
account.
• The installation is simple and may take up to 2
hours.
• Language used is Objective-C.

7. For Windows Phone Apps
• To develop Windows Phone apps, you need an
IDE called Visual Studio Popular and widely
used IDE by Windows.
• Download and install it.
• The installation is simple and may take up to 2
hours.
• Language used is C#.

8. Cross platform Development
• The Cross Platform Development is a modern concept
where you can develop apps for above OS with only one
language.
• Xamarine is the most popular and widely used Cross
Platform IDE.
• It uses C#.
• However, Visual Studio 15 by Windows also has the ability
for cross platform development.
• It also uses C#
• Another not much popular but handy IDE is the Intel XDK.
