The core function of Wadi is a tool for viewing and managing map files (Mapsforge/MBTiles) and GPS files (gpx/kml/kmz). In compliance with Google's private information protection policy, users with Android 11 (inclusive) or above must allow Wadi's "All File Access" permission to function properly.

1. POI file (point of interest file, *.poi): You can query surrounding waypoint information offline (for example: gas stations, mountains, communication points...)
