🚀 Mobile Development Basics
What is Mobile Development?
Native vs Cross-Platform Development
iOS vs Android Overview
Mobile App Lifecycle (Activity, ViewController, etc.)
Intro to Mobile UI/UX Principles
App Stores & Deployment Basics
💡 Decide early if you're going native or cross-platform.
📱 Native Development Paths
Android (Java/Kotlin)
