Offline Map use on Motorola Pro+ Phone
Hi, Orux
I created offline map via MobAC, it generated two files XX.otrk2.xlm & oruxmapsimage.db. I can display the map on my tablet.
When I try to use these offline map on my phone, it prompt me that it fail to load the map, database need upgrage??
When I create offline map directly on my phone, offline map display OK!!
In my case, Oruxmaps can only open offline map which is generated via the phone and not by MobAC !
I found four files were on the map folder..
xx.otrk2.xlm
oruxmapsimages.db
oruxmapsimages.db-shm
oruxmapsimages.db-wal
Whats the two files .db-shm & db-wal use?
Many thanks ...

Re: Offline Map use on Motorola Pro+ Phone
After some web search, found that ...
oruxmapsimages.db-shm ... is shared memory file for the database
oruxmapsimages.db-wal ... is write ahead log
It that my phone use different SQLite version compare with my tablet so all my old map cannot be read ?

Re: Offline Map use on Motorola Pro+ Phone
Problem solved !!
The two sqlite db files format are sqlite 3 but the database header offset 18 & 19 are different.
Database created by MobAC - offset 18 & 19 write/read = 01
Database created by Oruxmaps in the phone - offset 18 & 19 write/read = 02
Using hex editor to change 01 to 02, the map created by MobAC can be display on the phone ...
OruxMapsImages.db-shm & OruxMapsImages.db-wal will be created on the same folder.
