Memory consumption using OfflineMapTask

ERICDUCOS

Hi,

I have a piece of code in my Xamarin Forms apps that performs a test to know if a new Prepared Offline map is available. The code is a background task that run a loop and perform the query every X minutes...

Each time I am calling the  OfflineMapTask.CreateAsync to get the OfflineMapTask object, it consumes about 10 Mo memory and this memory is not released even when forcing Garbage Collection with GC.Collect()...There is no Dispose method...

And after a while, the apps breaks with an Out Of Memory error.

Can you tell me hao I can free the memory consumed by the OfflineMapTask.CreateAsync method ?

Regards.

Eric.

Thanks Eric.

We are working with an already existing map file on our device. We are using below code to load the map.
In doing so, I think the "tilecache" and "vectorTiledLayer" objects are not disposed from the memory. Do you know any other way of loading the offline maps?

 

 

var mapPackageFolder = Constants.TpkFolderLocation;
var mapPackageFile = @"Tas_WebM_BaseMap_no_contour.vtpk";

var mapPackagePath = System.IO.Path.Combine(mapPackageFolder, mapPackageFile);

var tileCache = new VectorTileCache(mapPackagePath);

ArcGISVectorTiledLayer vectorTiledLayer = new ArcGISVectorTiledLayer(tileCache);

map = new Map(new Basemap(vectorTiledLayer));

// Create starting viewpoint
Viewpoint startingViewpoint = new Viewpoint(
-42.882317, 147.327125,
10000);

map.InitialViewpoint = startingViewpoint;

return map;
