Convert survey layers to GPKG about qgis-plugin

[dracic]

I have a question about GPKG layers and Mergin support. Since GPKG layers have mandatory primary key field (feature id), and QGIS creates that field as auto increment integer, doesn't that make GPKG format less suitable for multiuser sync? So every user starts with 1,2,3..., and at the moment if you try to sync GPKG survey layer from multiple devices you will get sync_errors beacuse of primary key violation.

Hi @dracic

With the recent version of the mergin plugin and the APK from here MerginMaps/mobile#489 (https://www.dropbox.com/s/p6zoq70i9nesafw/input-489-330128471ae7a19aaf26669b7e9b09b3793b7005-arm64_v8a-signed.apk) you should be able to do edits from multiple sources/users to the same geopackage. Geodiff handles all changes and consolidates the diffs from multiple clients.

Please note that the Input APK is still beta. But if you are doing some trails, would be good to use the APK and let us know your feedback/suggestions.

Great! I will try it ASAP!
