Retrieve Envelope of a saved map in ArcGIS Online

Question

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.

I did not had time toi update the thread… Thanks to get read of my thread.

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.
