what is modify_positioning fr?

Modify Positioning is an Android app that lets you set a fake GPS location without rooting your phone. It works by using Android's own official mock location feature, which lets a designated app feed test coordinates into the phone's normal location system so that other apps checking for GPS, network, or fused location can read them. The stated goal is to give developers and testers a reliable way to check how location based features, like map pin selection or foreground location services, behave under different simulated positions. Once you pick a point on the map, the app starts a foreground service that pushes that location into the system repeatedly, and instead of holding a location that never moves, it drifts gently around the target so the reading looks closer to how a stationary phone actually behaves. It writes the same simulated position into three places at once, the GPS provider, the network provider, and Google's Fused Location Provider, so anything reading location through the standard Android APIs sees a consistent result. It also includes a diagnostics screen showing device details, permission status, and whether each of those three location channels is currently healthy, along with preset travel scenarios for Los Angeles and New York that can be used as templates for further testing. The default map source is OpenStreetMap, with an optional AMap integration available if you supply your own API keys. A separate iOS focused approach is referenced through a Git submodule that points to another developer's project, and the README is explicit that this iOS piece is not original work from this repository. The README states clearly what the project does not attempt: it does not hide the fact that mock locations are active, does not try to defeat any specific app's detection of simulated locations, and does not use root access, Xposed style hooking, or altering other apps directly. Built in Kotlin using Jetpack Compose, it requires Android Studio, JDK 17, and can be built and installed using standard Gradle commands.
