Project description:
"I have a React Native mobile app that streams the user’s position to our API through a foreground service. On Android 12 everything runs flawlessly, yet on Android 15 the moment I tap “Start Tracking” the app stops unexpectedly.

Key facts
• Permissions—ACCESS_FINE_LOCATION, ACCESS_BACKGROUND_LOCATION, and FOREGROUND_SERVICE—are already granted on Android 15.
• Background tracking is implemented as a foreground service (no WorkManager or AlarmManager).
• The crash gives no visible stack trace; the system dialog just reports “App keeps stopping.”

What I need
1. Diagnose the exact cause of the Android 15 crash.
2. Supply the code or Gradle/Manifest changes required to restore continuous location updates.
3. Explain the fix so I can replicate it in staging and production builds.

Acceptance
The patched APK must:
• Start and stop tracking without crashing on Android 15 devices.
• Keep sending location updates while the app is in the background or screen-off state for at least 30 minutes.
• Pass Play Store policy checks for background location and foreground service usage.

I can provide the existing React Native project, the native Android modules written in Kotlin, and logs collected with adb. Once the solution runs cleanly on Android 15, I will merge and deploy." (client-provided description)
