This is an Android application for scanning gauges/meters and capturing their readings using the CameraX API. The captured readings are stored locally in a Room database and can be synced to a server on-demand using a sync action.
Clone this repo and open in Android Studio.

- Language: Kotlin
- UI: Jetpack Compose with Material3
- Architecture: MVVM
- Dependency Injection: Dagger-Hilt
- Asynchronous Operations: Kotlin Coroutines
- Background Tasks: WorkManager
- Network: Retrofit
- Database: Room
- Hardware: Camera (CameraX API)
- Simulated Gauge Reader: Capture gauge readings using CameraX.
- Reading Listing: View captured readings from the local database.
- Report Screen: Visualize data using a line chart.
- Dark Mode: Built-in support for dark mode.
- Sync Now: Trigger server synchronization manually.
- Issue: Multiple types flows streaming data to single state object for ui layer.
- Solution: Collected data from one flow and emitted in another.
- Issue: Managing concurrent WorkManager requests and identifying them.
- Solution: After investigating the work manager behavior using debugger. Added tags and replace existing policy to distinguish work requests.
There’s always room for improvement in terms of design and architecture. Future enhancements could include:
- Optimizing data pipelines: Combine flows to streamline data streaming between MVVM layers.
- Improved user interface and user experience design.
