Open a project¶

Um ein Projekt zu öffnen, tippe auf Menü –> Optionen –> Projekt öffnen

Wähle das Projekt, das geöffnet werden soll im Dateiverzeichnis oder verwende die Verknüpfungen unter Aktuelle Projekte und Favoriten.

Favorite directories¶

In the first screen of the file selector, there is a section showing the favorite directories. To add a directory to the favorites, long click in the file selector on the directory name. To remove an entry from the favorites, long click on the entry in the favorites list.

Advanced project selection¶

QField opens QGIS projects in the „.qgs“ or „.qgz“ format.

QField uses a customized file selector to open the projects. On choosing „Open project“ from the QField menu, the file selector will be opened showing the following locations:

The primary media/shared storage directory.
The application-specific directories on all shared/external storage devices where the application can place persistent files it owns if they are not already included in the primary storage directory.

Inside these directories, only subdirectories and files with the „.qgs“ or „.qgz“ extension are shown.

QField requires the project file to be physically on the device, so it is not possible to use providers that work with remote files (e.g. Google Drive). On the other hand you can use apps like syncthing or nextcloud (or dropbox and probably many others) that allow you tho physically sync the file to your device.

Externe SD Karte¶

The file selector shows the root of the SD card labeled as „read-only“ and the application-specific directory separated from the rest of the SD card, as it is the only directory for which the app has write access. The directory is the following:

/Android/data/ch.opengis.qfield/files

Note

Technically, this is due to the fact that Android intents ACTION_OPEN_DOCUMENT and ACTION_OPEN_DOCUMENT_TREE, work and grant read-write access on the content of the returning URI, not on the real linked file. This limitation which makes sense for how Android is structured but currently it is unusable with QField as QField needs to access the real file with a real path.

Warnung!¶

By storing data in this folder, you risk losing data. The application-specific directory (/Android/data/ch.opengis.qfield/) will be deleted by the system if you uninstall QField from your Android device. This is important if you keep the data in the External sd card.

How to turn external SD card into internal storage¶

Starting from Android 6.0, you can use the SD card as internal storage for your Android phone. A feature called Adoptable Storage allows the Android OS to format an external storage media as a permanent internal storage. The data on the adopted SD card is encrypted and it can’t be mounted on another device.

Please be sure you start with an empty SD card. It needs to be empty because when the card is converted to „Internal“ storage, it will be formatted (wiped).

Gehen Sie auf „Einstellungen“ ihres Gerätes, dann wählen Sie „Speicher“.
Wählen Sie Ihre „SD-Karte“, tippen Sie dann auf das „Drei-Punkte-Menü“ (oben rechts) und wählen Sie dort „Einstellungen“ aus.
Wählen Sie zunächst „Formatieren“ aus und dann „Löschen und Formatieren“.
Ihre SD-Karte wird nun als interner Speicher formatiert.
Starten dein Telefon neu.

If you don’t reboot the phone, many things may not work correctly, so make sure you do.

It might be possible that the Adoptable Storage feature is not present on your device even if it is running Android 6.0 and above. The device manufacturer may have disabled the feature. However, command-line methods exist which allow you to force a device to adopt a storage.
