Field Maps Offline Area Download Failed
Dibe Naro
I am just wondering if anyone else has been having this issue. I can set up an offline area in the Field Maps online web application, then when I try to download that offline area on Field Maps Mobile (tested on two android devices) I receive the "Offline Areas Failed to Download" Error and the log tells me that feature tiling is disabled. Now this is frustrating. However, when I create on offline area in the Field Maps Mobile App, the map is created an downloads just fine.
It would be good if anyone from ESRI could confirm if there was some sort of limit to the number of features with attachments or best practise with attachments. In my case I want as a read only reference layer a point layer which may have several hundred points each with a single photo attached. Is that asking too much of field maps?
So I decided to downgrade the image size of my attachments because when you click on a dot to see its attachment (in field maps) it does not appear to be a zoomable image. So I decided to resize the images to 800x600 pixels which significantly reduces the file size. This allowed the download to complete without error and I get to keep the whole dataset, no need to break it up into several "Map Areas".
I'm having the same issues described in this thread and have really been banging my head over what the issue could be... Everything was working fine then all of a sudden, our field staff are getting these download failures which I'm able to replicate. Map areas of a smaller size work fine but larger areas fail to download in Field Maps (both within the app and in the online map area creation).
After that I thought, is something wrong in layer1 (related table). So I exported the feature layer as FGDB and reuploaded it to AGOL and created a TEST Map. Now this worked perfectly fine when I tried to download the offline area.
The next obvious step was to try and break the TEST layer. So created a new field with name of more than 31 characters. Then I tried downloading an offline area, the result was a fail with the same error.
Removed the troublesome field and I am able to download offline areas on my phone/iPAD.
A few other tests have confirmed this. It is the field length that causes the issue.
There is no limit (max 31 characters) in AGOL when you create a new field but when you try and download an offline area/replica then possibly that limit kicks in and the process fails.
Ill also add here that this problem will occur when your hosted feature service schema contains attribute field names that are reserved Sqlite words. For example, a hosted feature service can have a field named "group". If you try and download this feature service in an offline area you will get the above error as "group" is a reserved sqlite word. See _keywords.html for all words that you should never use in AGOL as field names.
Anyone else constantly frustrated by offline areas failing to download on ArcGIS Field Maps for no reason whatsoever? All the layers are set up for offline access and work perfectly fine online. The only solution is to just recreate the layers but this is a painful process when you have to do it so often! Any tips? Or just one of those things?
I have a map that spans the entire state and am creating offline map areas via a desktop web browser to use on our mobile device. All layers have sync enabled but are not editable. It is a read only map.
1) A package for an area is taking well over an hour, sometimes the whole day. These packages are 10 - 20 MB in size so I don't know why it takes so long. The layers are all hosted on the same AGOL site as the map, and all are correct in the areas that successfully are turned into offline maps.
2) One area for an offline map fails repeatedly. It appears there is some sort of smaller problem area within the area I'm choosing as I can make an offline area in one place and then try and make an identical size one adjacent to it and it fails. Since this area is using the same base map as every other successful offline area, I do not know why the failure is happening.
3) On my mobile device, I tried to create an offline area through the Field Maps App while connected to the internet. It fails with no error log or message. One moment its creating it, the next that area disappears from the list.
4) On the mobile device, it will not update any layers without completely logging out and logging back in and sometimes even that isn't enough and I have to delete the offline area from the device and grab it again. The device is an iPad with OS 14.4.1.
Same problem here (Sept 2022). It's so annoying having the field crew calling all the time complaining they can't download the offline area. Having productivity problems because of this and have no idea how to correct the problem. ESRI, c'mon !!!
I've read the blogs on taking maps offline to the best of my ability, and still nothing. I can create offline areas on the device through the Field Maps mobile app, but I can't create offline areas in Portal/Field Maps.
I had a similar problem on a 10.9.1 unfederated server. I was able to create and download the offline are through Field Maps but not through ArcOnline. My issue came to one of my layers not being secured on my server. Once I secured the service then added it to my ArcOnline with stored credentials, then I was able to package the offline area in ArcOnline. Hopefully this helps!
Hi @LisaMcAleer . I've stumbled upon this issue myself. I'm able to create an offline area thru my mobile device but am unable to preemptively create them thru the WebMap in Portal. I am using an ArcGIS Online basemap which I manually added to my Portal as an item. I read the link you previously provided regarding preparing offline basemaps. Does that script essentially do what I have done, just automated? I am still having the same issue when using an ArcGIS Online basemap as an item. Thanks!
When Collector and Field Maps added functionality for designing Offline Map Areas ahead of time for users to download to mobile devices I thought it would be a great tool. We have a large field crew that is constantly working in new areas without reliable service and they need to quickly be able to download an exact site without much fuss. Using Enterprise 10.8.1.
However, almost every time an offline map area attempts to download it fails. All of the Hosted Services, Basemap, etc. are configured for offline use appropriately - I'm packaging at a reasonable minimum scale for our work - and still I get the message that an error occurred downloading the map area. Server log references a Missing Layers warning even though all the layers are present and accounted for.
I don't mean to hassle the forum with tech support questions but this problem has been driving me nuts. Nobody's happy, everyone's confused, and a really cool or helpful feature ends up being more trouble than it's worth. If anyone has a workaround or a workflow that has allowed them to reliably download offline map areas created from Portal I'd be happy to hear them!
If i publish just the new editable layer offline it works by itself. But when i put the editable layer and the previous layers in the same field map i get syncing issue."Unable to Synchronize replica""Sync replica internal error"
When using a mobile device, there are few things more frustrating than losing internet connection, being in an area without Wi-Fi, or experiencing slow network speeds. Thankfully, ArcGIS Field Maps provides a few different options for taking maps offline, so your work is never interrupted due to a loss of connection. This means you can take your maps anywhere, be that in rural areas, a wildlife preserve, or even that spot in town notorious for slow internet speeds.
Map areas allow you to package your data, basemaps, and attachments for download. Once map areas are downloaded to your mobile device, you can use them to view assets and collect data offline, just as you would in a connected environment. There are two ways to create map areas: ahead of time using the Field Maps web app, and on demand using the Field Maps mobile app.
MMPKs allow you to take data or advanced symbology offline. They are created and shared using ArcGIS Pro and can be downloaded or sideloaded (copied) onto mobile devices. Sideloading maps is helpful for large file sizes because it eliminates the time required for download. MMPKs are read-only and do not support data collection. To learn more about MMPKs, see Create an MMPK for download and watch the following video:
From this page, you can enable offline mode, enable layers for sync, create map areas (as mentioned earlier), adjust feature and attachment delivery settings, and set an on-device tile package to use as the offline basemap. To learn more about the offline settings in the Field Maps web app, see Configure the map to work offline.
