DeviceScope APK Build Instructions

Method 1: Using Expo Go App (Recommended for Testing)

1. Install Expo Go on your Android phone from Google Play Store

2. Start Development Server:

   npm start

3. Connect to Your App:

   • Scan the QR code displayed in terminal with Expo Go app
   • Your app will load directly in Expo Go for testing

Method 2: EAS Build (Cloud Build) - Requires Expo Account

1. Create Expo Account (if you don't have one):

   • Go to https://expo.dev and sign up

2. Login to EAS:

   npx eas login

3. Initialize EAS Project:

   npx eas init

4. Build APK:

   npx eas build --platform android --profile preview

5. Download APK:

   • After build completes, you'll get a download link
   • Download and install on your phone

Method 3: Local Build (Advanced)

1. Install Android Studio and setup Android SDK

2. Setup NDK:

   • Install Android NDK through Android Studio
   • Set ANDROID_NDK_HOME environment variable

3. Build Locally:

   npx expo prebuild --platform android
   cd android
   ./gradlew assembleDebug

4. APK Location:

   android/app/build/outputs/apk/debug/app-debug.apk
   

Method 4: Instant Testing with Expo Development Build

1. Install Expo Development Build on your phone:

   npx eas build --profile development --platform android

2. Install the development build APK on your phone

3. Start development server:

   npx expo start --dev-client

Recommended Approach

For immediate testing, use Method 1 with Expo Go app. It's the fastest and requires no additional setup.

For a standalone APK that works without Expo Go, use Method 2 with EAS Build.

Troubleshooting

If you encounter NDK issues with local builds:

1. Update Android Studio to latest version
2. Install NDK through SDK Manager in Android Studio
3. Set proper environment variables
4. Clear gradle cache: cd android && ./gradlew clean
