Introduction to Mobile Application Development

Subject: Mobile Application Development (VU-CSS 223)
A mobile application, or mobile app, is a software application designed specifically for use on mobile devices like smartphones and tablets.

Introduction
Mobile phones and tablets have become essential tools in communication, education, business, entertainment, and health. As the demand for mobile applications grows, developers must understand how mobile systems work, the tools used, and how applications are built.

This lesson introduces the mobile development ecosystem and lays the foundation for full-stack mobile development using Python.

Mobile Operating Systems
There are two major platforms used in mobile application development:

Android
- Developed by Google
- The most widely used mobile OS globally
- Open-source and supports a wide range of devices
- Programming languages: Java and Kotlin
- App marketplace: Google Play Store

iOS
- Developed by Apple
- Runs on iPhone and iPad
- Known for stability, security, and premium user experience
- Programming languages: Swift and Objective-C
- App marketplace: Apple App Store

Types of Mobile Applications
Mobile apps can be built using different approaches depending on the target platform, performance needs, and development resources.

Native Applications
- Developed specifically for one platform (Android or iOS)
- Offer the highest performance
- Access to all device features
- Require platform-specific languages (Android=Java/Kotlin, iOS=Swift)

Hybrid Applications
- Developed using web technologies (HTML, CSS, JavaScript)
- Run inside a native browser container
- Easier cross-platform development
- Examples: Ionic, Apache Cordova

Cross-Platform Applications
- One codebase runs on both Android and iOS
- Faster development and cost-effective
- Examples: Flutter(Dart), React Native(JavaScript), Kivy(Python)


Why Python and Kivy for Mobile Development


Many students believe mobile apps can only be built with Java, Kotlin, Swift, or Flutter.
However, Python through frameworks like Kivy provides a simple, flexible way to build mobile apps without learning a new language.
This makes Python/Kivy perfect for beginners, educators, and rapid prototyping.

Why Python?
- Beginner-Friendly and Easy to Read: python has simple, human-readable syntax. Students learn faster compared to Java/Kotlin.
- One Language for Everything: with Python, students can build mobile app (Kivy), web app (Flask/Django), Machine learning, Data processing and Automation scripts
- Cross-Platform Support: code written once can run on Windows, Linux, macOS, Android (via Buildozer)
- Strong Community and Learning Resources

Note: Basic Python programming knowledge is a perquisite for the course. See or search for our python class

Cross-Platform Application offers better user experience and faster productivity. Kivy is a powerful Python framework for building cross-platform mobile applications from a single codebase. It enables rapid development and consistent UI across Android and IOS.
