Your First Android App

Android apps reach billions of devices worldwide. Let's understand how to build one.

**What you'll need:** - A computer (Windows, Mac, or Linux — all work!) - Android Studio (Google's free development tool) - An Android phone or tablet (optional — emulator works too) - An idea for an app!

**The technology:** - **Jetpack Compose** - Android's modern UI toolkit (like SwiftUI!) - **Kotlin** - The modern language for Android - **Android Studio** - Where you write and test your app

**Why Android:** - 70% of smartphones worldwide run Android - No Mac required (unlike iOS) - Google Play has more relaxed app review - One-time $25 developer fee (vs Apple's $99/year)
