description	Expert in Capacitor cross-platform development and Android native Java code for background services and battery optimization.

Capacitor & Android Native Bridge Skill

This skill enables the assistant to handle the complex interaction between the Web layer (React) and the Native layer (Java/Android) specifically for background tracking.

Knowledge Areas

1. Android Foreground Services

• Lifecycle Management: Start/stop/restart logic for LocationTrackingService.java.
• Notifications: Maintaining persistent notifications required by Android for foreground tasks.
• Boot Persistence: Implementing BOOT_COMPLETED receivers to restart tracking on device reboot.

2. Battery & Power Management

• Wakelocks: Smart management of PARTIAL_WAKE_LOCK to balance tracking consistency with battery life.
• Doze Mode: Using AlarmManager.setExactAndAllowWhileIdle() for reliable 60s intervals.
• Optimization Whitelisting: Handling REQUEST_IGNORE_BATTERY_OPTIMIZATIONS.

3. Capacitor Plugin Development

• Bridge Communication: Efficiently passing data between ProTrackingPlugin.java and React.
• Native-to-Web Events: Using notifyListeners for real-time status updates in the UI.

4. Background Geolocation

• Providers: Fine-tuning FusedLocationProviderClient settings (Priority, Interval, FastestInterval).
• Permissions: Managing granular location permissions (Fine, Background) and notification permissions.

Guidelines for Responses

• When modifying Java code, ensure Thread Safety (especially for network calls and location updates).
• Always recommend releasing Wakelocks when the GPS fix is obtained or if a timeout occurs.
• Suggest exponential backoff for failed HTTP requests in LocationApiClient.java.
• Keep in mind Android 14+ requirements (Foreground Service Types).
