## App Installation Rules
|
|
|
|
**Always use `adb install -r` to install the app. Never use `flutter install`.**
|
|
|
|
`flutter install` uninstalls the old version first, which wipes app configuration (API URL, sound file paths, etc.). `adb install -r` performs an in-place upgrade that preserves all app data.
|
|
|
|
### Installation Steps
|
|
|
|
```bash
|
|
# 1. Build
|
|
flutter build apk --release
|
|
|
|
# 2. Install (in-place upgrade, preserves config)
|
|
adb install -r build/app/outputs/flutter-apk/app-release.apk
|
|
```
