Collector-Download error

Courtney360 — Wed, 22 Oct 2014 14:10:11 GMT

I created a map for use in Collector and it contains a downloadable ESRI basemap, one feature service, and one tile layer. When I attempt to download the map to my i-pad I get this error: “Map download Failed. Unable to download the map. Invalid Levels.” If I remove the tile layer the map downloads fine, so this leads me to believe the tile layer is the problem. When I published the tiles I checked the box “Allow clients to export cache tiles.” The weird thing is that this worked just a few weeks ago. Has anyone else seen this??

I updated the Collector app on my i-pad and now I get this error message: “Map Download Failed. Unable to download the map. Unable to export tiles. Tiles available only for this level(s) [16, 17, 18] hence not able to export tiles for this specified levels [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17].”

It sounds like your tiled layer doesn't support exporting tiles at levels 0-15 (it supports only 16-18) and you are trying to download an area that requires tiles at those levels. Try zooming in when selecting the area to download so that you are zoomed into level 16-18 and can see those tiles, then download. That will limit the levels that you download.

Hi Gary,

Thanks for your response. I actually already tried zooming into levels 16, 17, and 18 but I still get the same error message....

Can you share that map to a group with Collector4ArcGIS and we will take a look at the issue you are seeing.

Best way to do this is to create a group, invite Collector4ArcGIS into that group, share the map and services into that group. Then post the name of the group and the map here and we'll take a look at it.

That particular tiled layer is being hosted on arcgis.com. However, hosted tiled services are not yet supported for downloading. This will be supported in a future release.

Currently, you can download tiled services that are hosted on your own server. If you have a host running ArcGIS Server 10.2.2 or later, you can download those tiled services.

That is so bizarre because it actually worked a few weeks ago! Nonetheless, I appreciate you looking into this, especially as quickly as you did.

I am having this exact same error message when attempting to take a ArcGIS Online hosted tile layer offline. This original post was prior to this functionality being enabled, however now this should be no issue at all. I even tried enabling the "Allow clients to export cache tiles" under the advanced caching settings at the time of publishing the service--still no luck. Any thoughts?.

Any improvements in this sense? I was also hoping to download tiled layers hosted on my organization account of arcgis.com. Seems that three years later this functionality has not been added yet. Is this correct?

Hi Alessandro - The support has improved over the years. Tile layers that are hosted on ArcGIS Online (or ArcGIS Enterprise, or Portal for ArcGIS) are supported for download (excluding vector tile layers). Are you hitting an issue in trying to do so?

Hi @Kylie Donia. The tiles I was trying to add were cached with AGOL tiling scheme, but only from level 12 (1:144447.638572) on. When I tried to download them onto Collector, I received an error like "Unable to export tiles. Tiles available only for this level(s) ["some levels starting from 4 more or less"] hence not able to export tiles for this specified levels [0, 1, 2, ... "I don't remember"].”. This didn't seem a problem related to AGOL capability to me, rather a matter of level of details of my scales. So I republished my hosted tiled layer to my organizational AGOL, this time with all levels from 0 to the one I needed, and it finally worked. I think there might be a bug probably, but I am not sure about it. Please, let me know if i can be of any help to this regard. Thanks.

I'm glad you have got it working! Yes, there is a bug and right now you do need to build ArcGIS Online tile layers starting with level 0. BUG-000089119: A web map does not download in Collector for ArcGIS .

There are also some tips for this in this post: https://community.esri.com/message/657422-unable-to-download-map

Hi Kylie Donia's Blog,

mentioning issues with operation of downloading service map from Collector, maybe you can give us a hand. We are facing a Collector (version 18.0.1, build 1031) error message when we try to download a map we have published in AGOL (coming from our geodatabase in arcgis server 10.4.1 in SQL Server (2012)). We use arcgis desktop 10.4.1 to create the data. Collector running on Windows 10, Android 7, and iOS 10.

The error message:

"Map Download Failed.

The operation couldn't be completed. Error while writing layer info in SqLite geodatabase."

This haven't happened before with previous versions of Collector for the same kind of service map and same arcgis desktop and server - 10.4.1.

Thank you in advance.

OK the reason for the issue was due to archiving status of some items inside the geodatabase.
