Hi Chad,
I am having multiple issues,I am listing down the issues:
Code Snippet of Download Geodatabase:
public async Task MakeMapAvailableOffline(UtiliSyncMap map, bool isManualSyc = false)
{
try
{
int currentLayerCount = 0;
foreach (var mapService in map.MapServices)
{
string mapServiceUrl = mapService.ServiceUrl.ToString().Substring(0, mapService.ServiceUrl.ToString().LastIndexOf("/"));
int layerAssociated = Convert.ToInt32((mapService.ServiceUrl.ToString().Substring(mapService.ServiceUrl.ToString().LastIndexOf('/') + 1)));
if (mapServiceUrl.Equals("https://services1.arcgis.com/BqQ60RORKMjmx3jf/arcgis/rest/services/SF_AGOL_TEST/FeatureServer") || mapServiceUrl.Equals("https://services6.arcgis.com/ExtdhXSbhHKK7FFW/arcgis/rest/services/SSMH_midvale/FeatureServer") || mapServiceUrl.Equals("https://services1.arcgis.com/BqQ60RORKMjmx3jf/arcgis/rest/services/Outfall_Template/FeatureServer"))
{
currentLayerCount++;
int downloadedPercentage = getDownloadedPercentage(currentLayerCount, map.MapServices.Count);
Acr.UserDialogs.UserDialogs.Instance.HideLoading();
Acr.UserDialogs.UserDialogs.Instance.ShowLoading(string.Format("Downloading {0} of Layers", currentLayerCount, map.MapServices));
continue;
}
#endregion
var credential = await AuthenticationManager.Current.GenerateCredentialAsync(new Uri(mapServiceUrl), "username", "password");
AuthenticationManager.Current.AddCredential(credential);
try
{
currentLayerCount++;
Acr.UserDialogs.UserDialogs.Instance.HideLoading();
int downloadedPercentage = getDownloadedPercentage(currentLayerCount, map.MapServices.Count);
Acr.UserDialogs.UserDialogs.Instance.ShowLoading(string.Format("Downloading {0} of Layers", currentLayerCount, map.MapServices.Count));
Debug.WriteLine("Getting Service Info for " + mapService.ServiceUrl);
if (!Directory.Exists("/storage/emulated/0/SmartMaps/OfflineMaps"))
{
System.IO.Directory.CreateDirectory("/storage/emulated/0/SmartMaps/OfflineMaps");
}
#if __UWP__
string gdbPath = Path.Combine(ApplicationData.Current.LocalFolder.Path, $"{mapService.MapServiceId}.geodatabase");
#else
string gdbPath = Path.Combine("/storage/emulated/0/SmartMaps/OfflineMaps", $"{mapService.MapServiceId}.geodatabase");
#endif
if (isManualSyc && File.Exists(gdbPath))
{
File.Delete(gdbPath);
}
var featureServiceUri = new Uri(mapServiceUrl);
var gdbSyncTask = await GeodatabaseSyncTask.CreateAsync(featureServiceUri);
//Saved extent details to setting file
double XMin = Convert.ToDouble(Settings.XMin);
double YMin = Convert.ToDouble(Settings.YMin);
double XMax = Convert.ToDouble(Settings.XMax);
double YMax = Convert.ToDouble(Settings.YMax);
int wkid = Convert.ToInt32(Settings.SpatialReference);
Envelope extent = new Envelope(XMin, YMin, XMax, YMax, new SpatialReference(wkid));
var generateGdbParams = await gdbSyncTask.CreateDefaultGenerateGeodatabaseParametersAsync(extent);
generateGdbParams.SyncModel = SyncModel.Layer;
generateGdbParams.LayerOptions.Clear();
generateGdbParams.LayerOptions.Add(new GenerateLayerOption(layerAssociated));
generateGdbParams.ReturnAttachments = false;
GenerateGeodatabaseJob generateGdbJob = gdbSyncTask.GenerateGeodatabase(generateGdbParams, gdbPath);
generateGdbJob.JobChanged += OnGenerateGdbJobChanged;
var gdb = await generateGdbJob.GetResultAsync();
Debug.WriteLine("Submitted job #" + generateGdbJob.ServerJobId + " to create local geodatabase");
}
}
}
}
Code Snippet to display Maps:
if (UtiliSyncMap.IsMapDownloaded)
{
for (int i = 0; i < UtiliSyncMap.MapServices.Count; i++)
{
string gdbPath = Path.Combine("/storage/emulated/0/SmartMaps/OfflineMaps", $"{UtiliSyncMap.MapServices.MapServiceId}.geodatabase");
await CreateFeatureLayersAsync(gdbPath, map);
}
}
private async Task CreateFeatureLayersAsync(string gdbPath, Map myMap)
{
try
{
// check if the file is exists in the local drive or not.
if (File.Exists(gdbPath))
{
gdb = await Geodatabase.OpenAsync(gdbPath);
if (gdb.GeodatabaseFeatureTables.Count == 0)
throw new Exception("Downloaded geodatabase has no feature tables.");
GdbTables = gdb.GeodatabaseFeatureTables.ToList();
foreach (var gdbTable in gdb.GeodatabaseFeatureTables)
{
await gdbTable.LoadAsync();
var fl = new FeatureLayer(gdbTable);
FeatureLayers.Add(fl);
myMap.OperationalLayers.Add(fl);
}
}
FeaturesLoaded = true;
return myMap;
}
catch (Exception ex)
{
return null;
}
}
