I saw some answers on this forum about some of the same trouble but as nothing worked for me and I discovered another trouble, I write a new post.
My gear : Sony Experia Z3 (Android 5.1.1) + Oruxmaps 6.5 + maps format .rmap (used to work perfecty on my old smartphone running under Android v3.x)
My two problems :
1- totally unable to read the maps on the SD card, due to the unabilit of Oruxmaps to write (but why should it be able to write ?) on the SD card. I tried almost everything I found on the internet to solve it, but nothing worked. For example, on the manual for v6.0 version it is written "you must copy your maps in :
/storage/extSdCard/OruxMaps/mapfiles/" but neither with my computer nor with the internal file explorer of my smartphone does Oruxmaps accept to read "extSdCard" folder. More, my sdcard is named "sdcard1" in Oruxmaps file explorer.
2- due to the desperate situation I finally copied the maps inside the memory of the phone, in the mapfiles folder. Even there, Oruxmaps displays an error message "there were problems reading some maps!" followed by the name of the map.
Any clue to solve it ?
thanks
