sorry, no idea. The project oruxmaps seems to be closed source and unmaintained (last release is from Nov 2013).
It is closed source, but I would not claim that it is unmaintained. Curiously, the "downloads" page is not listing the Android releases. According to http://www.oruxmaps.com/cs/en/more/history the most recent release is 7.0.4 from March 2017.
Besides that I think it is not a good idea to use a rather outaged and undocumented format like the old Garmin img format for a new platform like Android.
I agree. That said, Oruxmaps can be a reasonable option on an older Android device where the open-source OsmAnd would constantly crash due to running out of RAM. OruxMaps supports also many sensors, such as bicycle cadence sensor and heart rate sensor. I have some experience from OruxMaps 6.x with Brouter and MapsForge maps. (Because MapsForge uses the SD card for caching bitmaps of rendered vector map tiles, it is less memory-hungry than OsmAnd, which does not implement such caching.) If only there was an OSM-based open-source Android solution that would support address search, good-quality routing (with live recalculation) and recording of sensor data, all well integrated into a single program. Maybe OsmAnd could evolve to something like that if you accept that it would not necessarily run on a device with less than 2MiB RAM. Marko
