Opens and displays a scene from a Mobile Scene Package (.mspk).
Use case
A mobile scene package is an archive containing the data (specifically, basemaps and features), used to display an offline 3D scene.
How to use the sample
When the sample opens, it will automatically display the Scene in the Mobile Scene Package.
Since this sample works with a local .mspk, you will need to download the file to your device.
How it works
- Create a
MobileScenePackage
using the path to the local .mspk file. - Call
MobileScenePackage.loadAsync
and check for any errors. - When the
MobileScenePackage
is loaded, obtain the firstScene
usingmobileScenePackage.getScenes().get(0)
- Create a
SceneView
and callsceneView.setView
to display the scene from the package.
Relevant API
- MobileScenePackage
- SceneView
Offline Data
- Download the data from ArcGIS Online.
- Open your command prompt and navigate to the folder where you extracted the contents of the data from step 1.
- Push the data into the scoped storage of the sample app:
adb push philadelphia.mspk /Android/data/com.esri.arcgisruntime.sample.openmobilescenepackage/files/philadelphia.mspk
