About storage path of map files:
I tried and found a solution!!
According to the FAQ on http://www.beonroad.com simply MOVE the whole BeOnRoad folder from internal device memory to the external memory, often the SD card.
Move the folder to the main directory of your SD card, NOT in any sub folder.
Use any good file browser on your android device to do that … my favourite is still Total Commander.
Then start the app again … it seems that the app is looking for all folders on any storage path on your device, it will find the moved folder on your SD card.
This works for me even on a device with Android 4.4.4 with restricted wrire access to SD card for all apps.
Anyone to reproduce?
If yes, this hint needs to be included in http://wiki.openstreetmap.org/wiki/Be-on-road
