Hello,
Thanks for the reply - that would explain it then. I was under the impression that it was in both Android and iOS versions of Collector.
I can tell you what I know, it is hard to troubleshoot as the people who are experiencing the issue are over 1000km's away and are field staff who are not within the office much. I was hoping to use logging to determine further what was happening.
The web map being used contains 1 polyline layer with 3500 records and 2 polygon layers with 4500 and 22000 records each viewed over the ESRI Imagery with Labels basemap. The operational layer data is stored as versioned featureclasses within our Oracle database and served using ArcGIS Server 10.7.1. No predefined map areas have been created as yet but this is something I am hoping to do when I can determine with the field staff which areas they need to take offline.
Due to the difficulty contacting the field staff I am not exactly sure of the version of collector used however it is not Collector Classic. As mentioned above I am also not sure of the size of the area that is being taken offline but some of the land that the team service is quite large. They use Samsung phones to do their collecting but I am not sure of the exact model.
They have tried to take maps offline while connected to the office wifi, home wifi and 4G cellular data but seem to experience the same issue - the download starts, seems to continue downloading for a long time and eventually fails. In contrast for myself and others who are attempted to troubleshoot this the offline maps work fine unless we go to large areas (e.g. 50km x 30km) in which case the following error below is returned (in the collector logs on my iOS device) relating to the basemap; the team managing the server assures me that the server logs indicate the jobs relating to taking operational data offline complete successfully.
Error downloading map: Error Domain=com.esri.arcgis.runtime.services.error Code=400 "Invalid URL" UserInfo={NSURL=https://tiledbasemaps.arcgis.com/arcgis/rest/directories/arcgisoutput/World_Imagery_MapServer/_ags483010445_ch?f=json, NSLocalizedDescription=Invalid URL, responseJSON={
error = {
code = 400;
details = (
);
message = "Invalid URL";
};
}}
This is about all I know right now if there is any other information you need please let me know - any help greatly appreciated.
Cheers,
Gino
