A problem with layer display in Android devices.

[brilliantfeat]

What is the bug or the crash? What were your expectations and what actually happened?

I encountered an issue while using QField: In my QGIS project, I set the display color of a layer using attribute values—specifically, I stored RGB values in a field and configured the layer to display colors based on these attribute values. After saving the project file and transferring it to the Android version of QField, the colors do not display correctly. However, they work fine on iOS and iPad. I hope to resolve this problem.

Steps to reproduce the issue

1.Set the display color of a layer using attribute values.

2.In QGIS, layers can be displayed normally according to the set attributes.

3.Copy the project and all files to the device, and open them on the device.
4.In iOS devices, layers can be displayed normally too.

5.In Android devices, layers can not be displayed normally.

Version

4.0.5-Aare

Operating system name

Android

Operating system version

Android 16

Reinstall QField

• I have a fresh install of the latest QField version, but the problem persists.
• Problem can be reliably reproduced, doesn't happen randomly.
• Problem happens with all files and projects, not only some files or projects.

@brilliantfeat , interesting -- please share a sample project.

Preliminary thoughts: this might have to do with your dataset character encoding (I see in your screenshot that the attribute names have non-latin characters).

One test that could be done here is a/ change the attribute name to latin characters only (merely as a way to confirm/eliminate the above assumption), and if this was not a geopackage dataset, try switching to that.

Following your guidance, I have renamed all layer attribute names to latin characters only, and all issues have been successfully resolved. Thank you very much for your valuable assistance.

@brilliantfeat , what was the dataset format? Shapefile?
