Capturing photos in QField

Question

I have created a SQLite point layer in a QGIS (ver 3.8.1) project with both the absolute and relative path to photos stored in a subfolder of the project. I've added an action to the layer, which works great. In the image below, "Path" is the fieldname pointing to the absolute path

I have also created an attribute form, with 2 text fields and the relative path field using the drag-and-drop designer. The widget type is set to "Attachment", and the integrated document viewer is set to image (you can't see it in the screenshot). This results in an attribute form within QGIS with the image embedded within it.

All of this works great in QGIS, and mostly in QFIELD. The difference is that when editing in QField I can take a photo and see it in the attribute form, and when I hit save it claims to save the record but it doesn't. The image is saved (in a subfolder of the project called DCIM, which is not configurable) but no record is created.

I found a reference from a couple of years ago which stated that the project had to be stored in the Android/data/ch.opengis.qfield/ folder, which I have tried on the SD card and the device memory. The device is a Samsung S8 with lots of available storage space.

There are several bug reports on GitHub which are the exact opposite, stating that the record is created but the image isn't saved (QField issue 571).

The attribute form designer is goofy, in that I can't seem to edit the fields after creating them. I have to delete and recreate, which makes it hard to confirm that I've tried every option, but I think that I have. Given that others are having a different problem I feel that maybe my problem lies there though...

Answer 1

The solution is to change the layer type to Shapefile. Don't ask me why... I also tried using the Spatialite driver without success.

Prior to trying Shapefile I did notice that I was receiving an error message in the log stating

QFIELD 
Cannot start editing
QFIELD
Feature could not be added
QFIELD
Could not save changes. Rolling back

which is very interesting, because I've got a number of Spatialite layers that I edit all of the time.

Answer 2

The pattern:

QFIELD
Could not save changes. Rolling back

brought me here. I do Qfield 1.5.3 - Piz Palü on a S8 with LinageOS (dreamlte 9 PQ3A).

Out of storage reasons i put the project on the SD card. When digitizing a new entry (recording a track or points with photos), i received the error message above. After checking all permissions with no effect, i transferred the project to internal storage. Now it works fine. Maybe this helps someone.
