Creating an app with offline capability

MichaelBell — Thu, 23 Sep 2021 00:04:09 GMT

I'm currently trying to create an app which has offline functionality, similar to Collector. That is, the user can go to their Gallery on the device (eg an iPad) and, if the map is able to be used offline, the user can select an area and create the downloaded package directly on their device, and sync it up as they go.

Is this possible? At the moment everything I can see points to having to create and package it up using ArcGIS Pro.

We support a lot of users who operate out of areas where they have no connection in the field, in different timezones and sometimes with emergency situations who can't wait for me to be online and packaging maps up and then them having to download them again, then doing it again if it's wrong. Much better if they can do it themselves just using the app.

@MichaelBell Yes it is possible. There are a few methods to achieve your goal. One is by using AppStudio and QML or QML with JavaScript or QML with JavaScript and C++. You can create an app in a way it syncs the tables/maps/layers etc. In AppStudio I believe there is an Example app that demonstrates working with layers and editing them and tables on and offline. Here is a link that might help you get started with AppStudio.

@MichaelBell

Yes, it is possible with AppStudio as @GISJot mentioned above. I also want to point out that AppStudio MapViewer template supports the offline workflow you mentioned, you just need to set up the Webmap with pre-planned offline map areas from ArcGIS Online. Then, you would be able to download those pre-planned offline map areas in MapViewer template.
