An Android app that continuously collects and stores GPS pings — even when the app is killed — and visualizes them on a map and in a list view.
The app is built with Kotlin, Jetpack Compose, Hilt (KSP), Room, WorkManager, and Google Maps Compose.
- ✅ Collects GPS pings in the background (at least 1 per hour)
- ✅ Works even if the app is killed (not just backgrounded)
- ✅ Shows pins on a Google Map with
maps-compose - ✅ Displays a list view of collected pings (time & coordinates)
- ✅ Uses Room database to persist location history
- ✅ Hilt integration with WorkManager
- ✅ API key is stored securely in
local.properties
