Android GPS Tracking Payload

I need a small, unobtrusive Android payload file that, once installed on a mobile phone, taps directly into the device’s GPS hardware and reports real-time latitude and longitude. My priority is reliable GPS tracking, not Wi-Fi or cell-tower fallback, so please build around Android’s FusedLocationProvider (or another lightweight GPS API you trust). The compiled APK should run quietly in the background, survive reboots, and forward coordinates to an endpoint I specify via HTTPS at set intervals that I can later tweak.

You are free to work in Java or Kotlin inside Android Studio, but keep external dependencies minimal so the file size stays lean. Please include full, well-commented source code, the signed installable APK, and a short README that shows how to:

• Change the reporting URL and interval
• Re-build and sign the payload
• Grant the necessary foreground and background location permissions under current Android security policies

A quick demo—simulator or test device—proving successful GPS capture and transmission will serve as acceptance criteria.
