I'm working on enabling offline sync in an iOS app using ArcGIS runtime 100.6. The back end is ArcGIS Enterprise 10.7.1. I created a web map which only uses the World Topography Map (for Export) as a basemap and a single feature service created by ESRI to as a controlled test to guard against any mistakes I could have made while publishing the services which the production app will need to consume. These should present no problem being taken offline, but this error is generated after I initiate the download: I checked the web map settings on portal. It is shared with everyone and the "offline mode" switch is enabled, so I don't understand how I could be getting this error. To clarify, the basemap loads successfully, but the feature layer does not. The code for initiating offline mode doesn't deviate much from the sample in this article (The function "downloadGeodatabaseForLayers() follows this article😞 func takeMapOffline ( areaOfInterest : AGSGeometry ) { //1.

Can someone suggest a solution?

Unable to take web map offline: "The feature service does not support geodatabase sync"

CoryDavis

I'm working on enabling offline sync in an iOS app using ArcGIS runtime 100.6. The back end is ArcGIS Enterprise 10.7.1.

I created a web map which only uses the World Topography Map (for Export) as a basemap and a single feature service created by ESRI to as a controlled test to guard against any mistakes I could have made while publishing the services which the production app will need to consume. These should present no problem being taken offline, but this error is generated after I initiate the download:

"The feature service does not support geodatabase sync"

I checked the web map settings on portal. It is shared with everyone and the "offline mode" switch is enabled, so I don't understand how I could be getting this error. To clarify, the basemap loads successfully, but the feature layer does not.

The code for initiating offline mode doesn't deviate much from the sample in this article (The function "downloadGeodatabaseForLayers() follows this article😞

If I download the app container, I can see both the mmpk file and the geodatabase file, but only the basemap displays. Can someone suggest a solution?

There is no reason to call the downloadGeodatabaseForLayers. Basically you are taking the map offline which will create a package that includes the tiles from the basemap and the data from the service (inside the defined boundary).

Inside the setup of taking the the takeMapOffline you define the parameter:

parameters<SPAN class="" style="color: #999999; border: 0px; font-weight: inherit;">.</SPAN>returnSchemaOnlyForEditableLayers <SPAN class="" style="color: #a67f59; background: rgba(255, 255, 255, 0.5); border: 0px; font-weight: inherit;">=</SPAN> <SPAN class="" style="color: #990000; border: 0px; font-weight: inherit;">true</SPAN>

So you are not returning data from the feature service.

Not 100% sure on your error, unless possibly testOfflineServiceUrl may not be correct as Cory Davis‌ mentioned

Thanks so much, this is exactly what I needed. Works great now!

Sorry mixed up my names in the above post....

Hi Cory,

As Mary and Joe pointed out, you shouldn't have to call downloadGeodatabaseForLayers and you shouldn't set returnSchemaOnlyForEditableLayer to true (that's why you're not getting any data).

There's a more fundamental issue which is, I think, why you might be seeing an error. You are not holding on to the OfflineMapTask, nor the Job. Not entirely sure why that would give you the error you're seeing but I suspect something is bubbling up internally and being caught by code that expects something specific.

Anyway, if you provide a class level var to hold the AGSOfflineMapTask and the AGSGenerateOfflineMapJob (see lines 34 and 35 below), and you remove the line that sets returnSchemaForEditableLayers, your code works:

Inside the setup of taking the the takeMapOffline you define the parameter:

parameters<SPAN class="" style="color: #999999; border: 0px; font-weight: inherit;">.</SPAN>returnSchemaOnlyForEditableLayers <SPAN class="" style="color: #a67f59; background: rgba(255, 255, 255, 0.5); border: 0px; font-weight: inherit;">=</SPAN> <SPAN class="" style="color: #990000; border: 0px; font-weight: inherit;">true</SPAN>

So you are not returning data from the feature service.

Not 100% sure on your error, unless possibly testOfflineServiceUrl may not be correct as Cory Davis‌ mentioned

Mary,

The error is triggered from downloadGeodatabaseForLayers. I added this function at the suggestion of an ESRI tech I worked with over the phone. I noticed the geodatabase was being downloaded before I added it (I could see the file in the app container), but none of the features I selected with the areaOfInterest geometry appeared on the downloaded map.

The value of testOfflineServiceUrl is Layer: Wildfire Response Points (ID: 0)

Dear Cory,

Thank you for submitting this question. I cannot immediately spot any problem with the code. I am unclear, however, as to why you are calling the downloadGeodatabaseForLayers function in order to take a map offline. You should be able to take the map offline without calling your function 'downloadGeodatabaseForLayers'.

Can you confirm where the error message is triggered from? Is it from the AGSGenerateOfflineMapJob.Start or from the downloadGeodatabaseForLayers function?

Also, what is the URL for the 'testOfflineServiceURL' that you are passing to the

let syncTask <SPAN class="" style="color: #a67f59; background: rgba(255, 255, 255, 0.5); border: 0px; font-weight: inherit;">=</SPAN> <SPAN class="" style="color: #d74444; border: 0px; font-weight: inherit;">AGSGeodatabaseSyncTask</SPAN><SPAN class="" style="color: #999999; border: 0px; font-weight: inherit;">(</SPAN>url<SPAN class="" style="color: #a67f59; background: rgba(255, 255, 255, 0.5); border: 0px; font-weight: inherit;">:</SPAN> <SPAN class="" style="color: #d74444; border: 0px; font-weight: inherit;">URL</SPAN><SPAN class="" style="color: #999999; border: 0px; font-weight: inherit;">(</SPAN>string<SPAN class="" style="color: #a67f59; background: rgba(255, 255, 255, 0.5); border: 0px; font-weight: inherit;">:</SPAN> testOfflineServiceUrl<SPAN class="" style="color: #999999; border: 0px; font-weight: inherit;">)</SPAN><SPAN class="" style="color: #a67f59; background: rgba(255, 255, 255, 0.5); border: 0px; font-weight: inherit;">!</SPAN><SPAN class="" style="color: #999999; border: 0px; font-weight: inherit;">)</SPAN>
