Rendering Mobile Map Packages

MarkCederholm — Tue, 29 Nov 2016 16:30:49 GMT

I'm seeing the same problems with Mobile Map Packages in the 100.0 release that I saw in the Beta. I cannot zoom or pan to the full extent of the data, and not all features are rendering properly. Is this issue still being worked on for a future release?

FYI, I was able to work around the pan/zoom issue by moving the layers to a new map instead of just assigning the MMPK map to the mapview. However, not all layers are present when I try to grab them, which is a head-scratcher. I may need to get tech support involved with this one.

Hi Mark,

Have you tried setting the extent of your map before creating the mmpk?

http://pro.arcgis.com/en/pro-app/tool-reference/data-management/create-mobile-map-package.htm

"If an extent is not specified, the visible extent of your map will be used to define the area of interest and consolidate only those features that intersect that extent."

Cheers

I've been explicitly setting the extent, and even when it's zoomed WAY out it makes no difference.

After revisiting the issue, I've determined that while ArcGIS Pro has no trouble re-importing MMPKs that I create, there seem to be some bugs and/or compatibility issues with Runtime. These are the three issues I'm running into:

Definition queries are not being honored
Labels do not display by default if enabled in the MMPK
Layers symbolized on multiple fields will not appear in the map

While the first two seem like actual bugs, the third may simply be a feature that's not yet supported. Esri did create a bug number (BUG-000102308 ) but I don't think it's worded well: it's not the MMPK itself that has problems, but the way Runtime is creating a map from it.

Hi Mark,

This may be a bug that we are currently working on. Try the following workaround and see if is helps:

Before you set the MapView.Map property to contain the .MMPK's map, add a base layer that has a larger initial extent (ideally the same base layer that you might have used in ArcGIS Pro to create the .MMPK). Then after you set the MapView.Map property, remove the base layer. The layers in the .MMPK will display at the extent as they were originally created in ArcGIS Pro. The unintended side effect of this workaround is that you can now zoom out past the original extent that was specific in ArcGIS Pro (but at least you can see all of the data).

Here is some sample code to demonstrate the workaround:

string thePathToMMPK = "C:\\Temp\\CurrentDisplayExtent.mmpk";
MobileMapPackage theMMPK = Await MobileMapPackage.OpenAsync(thePathToMMPK);
IReadOnlyList<Map> theMaps = theMMPK.Maps;
Map myMap = theMaps[0];

// WORKAROUND - Part1 (Add a base layer with a larger viewable extent)
var serviceUri = new Uri(http://services.arcgisonline.com/arcgis/rest/services/Canvas/World_Light_Gray_Base/MapServer);
ArcGISMapImageLayer baseLayer = new ArcGISMapImageLayer(serviceUri);
myMap.Basemap.BaseLayers.Add(baseLayer);

MyMapView.Map = myMap;

// WORKAROUND - Part2 (Remove the base layer)
LayerCollection myLayerCollection = MyMapView.Map.Basemap.BaseLayers;
myLayerCollection.RemoveAt(0);
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I hope this helps.

Hey Mark,

Great news! This issue has been fixed with ESRI's latest version of the ArcGIS Runtime for .NET (v100.1) that was just released yesterday (6/29/2017). Read all about the Update 1 capabilities in the blog post: https://blogs.esri.com/esri/arcgis/2017/06/29/arcgis-runtime-sdk-update-1-is-now-available/

Great, I look forward to checking it out.

Well, I don't know which issue you think is fixed, but I'm still having to use the add baselayer workaround on my example MMPK in order to zoom out beyond a certain scale. However, I can at least pan to the end of the data now. Anyway, I'll keep looking into MMPK issues with 100.1, and report any problems directly to tech support.

Hi Mark,

What version of ArcGIS Pro are you using to create your MMPK?

Cheers

Re: Rendering Mobile Map Packages

The original MMPK was created in 1.4.1 -- I just recreated it in 2.0, and the results are even worse. Of all the features and layers in the map, I'm only seeing one feature each from two layers.

Re: Rendering Mobile Map Packages

MarkCederholm — Mon, 03 Jul 2017 14:45:54 GMT

FYI, I just reimported the new MMPK into Pro 2.0, and it's crap. I don't think Runtime can be blamed for this problem.

Hi Mark,

Are you able to share the mmpk with the display issues you're seeing? If you can't upload here, please email me on mbranscomb@esri.com (up to 10MB). Alternatively I can setup a folder online.

Regarding some of the other issues you mentioned:

- Definition queries not being honored

- These should now be honored for Operational Layers (but not yet for Basemaps)

- Labels do not display by default

- This should have been be resolved in v100.1.

- Layer symbology on multiple fields

- On the roadmap for a future release

Cheers

Mike

I created a simple MMPK in Pro 2.0 that has no zoom problems, but the more complex maps are still problematic. At least I verified that, for a simple map, definition queries are honored if the MMPK is generated by 2.0 rather than 1.4.1.

For an example of a problem map, see this topic: 2.0: MMPK creation problems

Re: Rendering Mobile Map Packages

MarkCederholm — Wed, 05 Jul 2017 21:41:00 GMT

I successfully created a Pro 2.0 MMPK that imports back into Pro just fine, but still exhibits zoom and rendering problems in Runtime 100.1:

Map won't zoom to full extent unless a basemap layer is added.
Unwanted fills are added to certain polygon layers.

It's less than 3 MB, so I'll email it to you directly.

Is scale-based sizing supported in the runtime SDK with mmpk's generated from ArcGIS Pro 2.0 (or will it ever be)? That still doesn't seem to be carrying over.
