Using Locus Map on Android 11+ file system
What is this all about?
In November 2021, Google launched a new file management system in Android 11 and the following versions, bringing a major change to the way Locus Map and other applications handle their data:
- by default, the app has a full read/write access to its PRIVATE FOLDER in /Android/data/ system directory (either in the internal storage or in the external storage - removable SD card)
Advantages of the private directory
- App data is secured against access from other apps (possible attacks from malware etc.)
- After the uninstallation, the app leaves no garbage in the device storage.
Drawbacks
- All app data is deleted upon uninstall - the majority of devices show a warning prompt with the option to retain the app data in the storage. But especially Chinese products erase the data without an option of restoring.
- No use of other apps data - it is no longer allowed to share one common directory between Locus Map Classic and Locus Map 4.
- Limited custom sub-directories - the app can read/write maps only in its private directory or in /Android/media/ directory. Elevation data can be placed only in the app's private directory. Only backup files can be stored elsewhere. Also, custom directories with geotagged photos are not supported - Locus can read from the default system media directory only.
- Disabled linking to maps from external folders - all raster maps can be stored only in /Locus/Maps/ directory or in /Android/media/menion.android.locus/Maps/ directory, all vector maps in /Locus/mapsVector/ directory or in /Android/media/menion.android.locus/MapsVector/ directory.
As a precaution before the update to Locus Map 4.5.x or Locus Map Classic 3.56.x we urgently recommend:
- setting up an automatic backup of your tracks, routes and points to Dropbox, Google Drive or OneDrive. Premium Gold users' data are automatically synced with our own cloud server.
- regular backups of your downloaded maps especially from the commercial publishers. LoMaps can be re-downloaded for free any time from Locus Store.
What to do with it?
We've prepared a few scenarios for smooth and secure transfer of your data after the app update:
