The app has support for GPX and KML files, as well as the "geo URI scheme" and popular map services (google-maps, openstreetmap, yandex, ...). It can work offline (without Internet/WiFi) once geodata has been downloaded and cached. Other Android apps can use LocationMapViewer through an Intent-interface. Required Android Permissions: * INTERNET: to download map data from Open Streetmap Server * ACCESS_NETWORK_STATE and ACCESS_WIFI_STATE: to find out if wifi/internet is online to start downloaded geodata * WRITE_EXTERNAL_STORAGE (to cache downloaded map data in local file system and to load gpx/kml-Files to be displayed in the map) * ACCESS_FINE_LOCATION and ACCESS_COARSE_LOCATION: to display my own location in the map
