Class MobileMapPackage
A mobile map package.
Implements
Namespace: Esri.ArcGISRuntime.Mapping
Assembly: Esri.ArcGISRuntime.dll
Syntax
public sealed class MobileMapPackage : ILoadableRemarks
Mobile map packages allow you to work with maps on a mobile device. A mobile map package contains all of the files necessary to work with your maps and is stored on a device as either:
- A single archive file with a .mmpk extension.
- A directory containing an unpacked mobile map package.
You can create a mobile map package using either:
- ArcGIS Pro(from version 1.3). This version of the ArcGIS Runtime SDK supports any mobile map package up to major version 5. Mobile map packages created with ArcGIS Pro are stored in a file with an .mmpk extension.
- ArcGIS Runtime. Use the GenerateOfflineMap(GenerateOfflineMapParameters, String) method to generate and download a mobile map package on-demand, or use DownloadPreplannedOfflineMap(DownloadPreplannedOfflineMapParameters, String) to download a mobile map package already prepared by the map author. Mobile map packages created with the OfflineMapTask are stored in a directory containing an unpacked mobile map package.
A mobile map package can encapsulate one or more maps along with their layers and data. Each package contains an Item with metadata about the package (description, thumbnail, etc.).
Mobile map packages created with ArcGIS Pro can also include transportation networks, locators, and links to online services. You can choose whether to use:
- A tile package (such as .tpkx or .vptk) or an online basemap as the Basemap.
- A mobile geodatabase (.geodatabase) or an online feature service as one of the OperationalLayers.
Online services (such as traffic or weather) can provide excellent contextual information for your users. If the mobile map package is going to be used in areas of poor connectivity, however, you must ensure that data critical to your workflow is stored locally on the device.
Mobile map packages implement the ILoadable interface; you need to load the MobileMapPackage before you can access its content. Once loaded you can:
- Determine the version of this package using the Version property. ArcGIS Runtime currently supports mobile map packages up to and including major version 5. If the package is from an unsupported version, it will fail to load.
- Discover whether the mobile map package has expired using the Expiration property.
- Access the individual maps and display them in a MapView.
- Programmatically add, modify, and remove layers in the map. Mobile map packages, however, are read-only and these changes to maps or layers are not persisted.
