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 Pro 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 Pro 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?
Grant the app the "All files access" permission
The original default setting of the Locus Map main directory will remain in the root of the internal storage of the device. Plus, custom sub-directories will be allowed elsewhere in the internal or external storage (removable SD card), and external will be allowed to be linked to the app from anywhere in the device storage.
What happens without the "All files" permission?
The above mentioned setup will no longer be possible on Android 11+. Therefore, we've prepared a few scenarios for smooth and secure transfer of your data after the app update:
