Building APK Locally

Option 1: Android Studio

1. Run npx expo prebuild
2. Open android/ folder in Android Studio
3. Go to Build > Build APK(s)
4. Find APK at android/app/build/outputs/apk/release/app-release.apk

Option 2: CLI

npx expo prebuild
cd android
./gradlew clean
./gradlew assembleRelease

Install on device:

adb install app/build/outputs/apk/release/app-release.apk

---

Environment Variables

Create a .env file:

APPWRITE_ENDPOINT=https://cloud.example.io/v1
APPWRITE_PROJECT_ID=your_project_id

Use react-native-dotenv to load them.

Troubleshooting

• White placeholder text in APK
  → Set placeholderTextColor="#000" explicitly

• Hermes crash on APK boot
  → Guard segment[0] and context access in RouterGuard

• Appwrite auth warning
  → Ensure AuthProvider wraps layout in _layout.tsx

• EAS build fails
  → Use ./gradlew assembleRelease locally instead
