Im November 2021 startete Google a neues Dateiverwaltungssystem in Android 11 and the following versions), bringing a major change to the way Locus Map and other applications handle their data:

• the app has a full read/write access only to its PRIVATE FOLDER in /Android/Daten/ system Verzeichnis (entweder im internen Speicher oder im externen Speicher - wechselbare SD-Karte)

• The app shows a better performance in Stabilität und Reaktionsfähigkeit
• Its data is gesichert vor Zugriffen aus anderen Apps (mögliche Angriffe durch Malware etc.)
• After the uninstallation, it leaves kein Müll im Gerätespeicher.

• Alle App-Daten werden bei der Deinstallation gelöscht - Die meisten Geräte zeigen eine Warnmeldung mit der Option, die App-Daten im Speicher zu behalten. Aber gerade chinesische Produkte löschen die Daten ohne Wiederherstellungsmöglichkeit.
• Keine Verwendung von Daten anderer Apps - it is no longer allowed to share one common directory between Locus Map Pro and Locus Map 4.
• No custom sub-directories - Die App kann lesen/schreiben Vektorkarten und SRTM data only in its private directory (only backup files can be stored elsewhere). Also, custom directories with Fotos mit Geotags werden nicht unterstützt - Locus kann auslesen standardmäßiges Systemmedienverzeichnis nur.
• Verknüpfen mit Karten aus externen Ordnern deaktiviert - Alle Rasterkarten können nur in gespeichert werden /Ort/Karten/ Verzeichnis, alle Vektorkarten in /Locus/mapsVector/ Verzeichnis.

The original default setting of the Locus Map main directory was in the root of the internal storage of the device. Plus, custom sub-directories could be set elsewhere in the internal or external storage (removable SD card), and external maps could be linked to the app from anywhere in the device storage.

As this setup is no longer possible on Android 11+, we've prepared a few scenarios for reibungslose und sichere Übertragung Ihrer Daten nach dem App-Update:

When only a single app is installed on the device (the other Locus is not installed), the app update goes through the most simple and straightforward process.

So geht's >>

Older Android versions enabled sharing of the main app directory between Locus Map 4 and Locus Map Pro. This is no longer possible, each app can use only its own private folder. After the update, you have to decide whether to use only one of the apps or both with the data size doubled.

So geht's >>

The main app directory used to remain at the root of the internal storage of the device when the app was uninstalled. You can transfer such data after a new Locus installation.

So geht's >>

The newly installed app can detect the other app on the device and offers to transfer its data.

So geht's >>

Previously, Locus Map could work with data (maps, SRTM data, geotagged photos…) placed in subdirectories all over the device storage. As this is no longer possible, the data should be transferred to the private folder too.
