[Qgis-user] Mobile GIS

[Noli Sicad]

Hi Phillip,

Thanks for sharing your project and ideas.

Have you tried this app.

https://confluence.prodevelop.es/display/GVMN/Home

Probably you can borrow some of their codes to incorporate to what you
have started. It is GPL project as as well. I think there is no edit
function in the map viewer.

Regards,

Noli
