Creating a mobile map package for an arbitrary area of interest

Hi, we are trying to export a part of a map to a mobile map package. My approach looks like that:

import os import arcpy from arcgis.geometry import Polygon root_dir = "C:\\Users\\mobile\\Alex\\Projects\\ArcGIS\\Mist1" in_aprx = "Mist1.aprx" map_name = "Map" project = arcpy.mp.ArcGISProject(os.path.join(root_dir, in_aprx)) world_map = project.listMaps(map_name)[0] aoi_def = { "paths" : [[[-97.06138],[-97.06133,32.836],[-97.06124,32.834],[-97.06127,32.832]], [[-97.06326,32.759],[-97.06298,32.755]]], "spatialReference" : {"wkid" : 4326} } aoi = Polygon(aoi_def) arcpy.management.CreateMobileMapPackage( in_map = world_map, output_file = r"c:\\Users\\mobile\\MobileMapPackage1.mmpk", in_locator = None, area_of_interest = aoi )

Unfortunately, CreateMobileMapPackage does not accept a polygon as area of interest but requires a full blown feature layer. My question is: How do I programmatically create such a feature layer consisting of 4 pairs or longitude and latitude?

paths" : [[[-97.06138],[-97.06133,32.8 ....

missing something in the first pair ... is it a copy/paste error or did your code throw and error message

Thanks @DanPatterson, unfortunately the missing value was not the issue, the error remains the same.

I manually created a feature layer in ArcGIS Pro with one single polygon. When I then call the following function, the export seems to start (at least I don't get an error and the process runs for a while now):

arcpy.management.CreateMobileMapPackage( in_map = self.world_map, output_file = r"c:\\Users\\mobile\\MobileMapPackage1.mmpk", in_locator = None, area_of_interest = "NameOfMyManuallyCreatedFeatureLayerWithOnePolygon" )

But there MUST be a way to create the area_of_interest programatically, right?

And even when I can't create one, I must be able to edit the existing layer somehow. I tried that using these two functions. First, I get my feature layer using get_layers() which works fine.

def get_layers(self): layers = self.world_map.listLayers() fl = None for l in layers: print(l.name) if (l.isFeatureLayer): self.fl = l print("Found layer, exiting...") break def get_feature_layer(self): print("Feature url:", self.fl.URI) rfl = FeatureLayer(self.fl.URI) #print("RFL features:", rfl.query())

Then I try to convert the Layer instance to a FeatureLayer instance which seems to work fine, but I can not access the features using e.g. featureLayer.query() which fails with an invalid URL. But I don't expect to work with any only map since my map is a local file?

So my goal still is to create a FeatureLayer programatically in python OR edit an existing FeatureLayer. Hope anybody can help me.
