Location Map Viewer

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.
