📱 Android APK — Basic to Advanced Guide

1. Windows System Requirements

64-bit Windows 10/11, సిఫార్సు 16GB RAM, కనీసం 20GB free space, Flutter SDK, Android Studio/SDK, VS Code (optional), Git, USB Debugging.

2. Flutter Check

flutter doctor -v
flutter devices

3. Separate Practice App Create

cd "$HOME\Desktop"
flutter create --org com.example learning_demo
cd learning_demo
flutter run

4. Debug APK Build

flutter analyze
flutter test
flutter build apk --debug

Output: build\app\outputs\flutter-apk\app-debug.apk

5. Install on Android

adb devices
adb install -r "build\app\outputs\flutter-apk\app-debug.apk"

6. PWA vs APK

ఈ Learning Studioను HTTPSలో Host చేస్తే Android Chromeలో Install చేయవచ్చు. అది Native APK కాదు. Learning Websiteను APKగా Package చేయాలంటే ప్రత్యేక Android wrapper project, signing, testing అవసరం. Local HTML Filesను నేరుగా APK అని rename చేయలేరు.

7. Release Build

Release signing key, secure key.properties, correct applicationId, app icon, permissions, privacy policy, testing అవసరం. Debug signingతో Production Release చేయవద్దు.
