Hi (Sorry for the initial french thread...i just translated so that more people can understand and answer to me)...

I am writing an app using Xamarin ArcGIS component so that I can display a saved map stored in ArcGIS Online.

This is working well...

Now the next step is to prepare the things to work offline with this map.

I found the tutorial that describes the step to work on...

In the first steps, one step consists in defining the area of interest with the following code:

Envelope areaOfInterest = GetAreaOfInterest();

GenerateOfflineMapParameters parameters =await task.CreateDefaultGenerateOfflineMapParametersAsync(areaOfInterest);

As far as I am concerning, the area of interest is just the area I defined when saving the map in ArcGIS Online. The envelope can be displayed in one of the menu of ArcGIS Online.

Now my question is: how I can retrieve this enveloppe using the SDK from the Map object I created from the url ?

Regards.

Eric.

If I understood correctly you would like to use the initial extent of the webmap as an offline area that you generate?

Have a look to https://community.esri.com/thread/198068-downloading-map-from-portal-for-offline-use#comment-700103  which takes the portal items extent and uses that as an area of interest.

Thanks,

That is a way to do the things…

In the meantime, while debugging my project, I found that the Map object that I had created from Url contains an Item property of type PortalItem that have the waited data (as in tour given reference example).

I did not had time toi update the thread…

Thanks to get read of my thread.
