Display a web scene

Learn how to create and display a scene from a web scene stored in ArcGIS.

This tutorial shows you how to create and display a scene from a web scene. All web scenes are stored in ArcGIS with a unique item ID. You will access an existing web scene by item ID and display its layers. The web scene contains features layers for the Santa Monica Mountains in California.

Prerequisites

Steps

Create a new Android Studio project

1. To start this tutorial, complete the Display a scene tutorial. Or download and unzip the Display a scene solution in a new folder.

2. Modify the old project for use in this new tutorial. Expand More info for instructions.

   More info

   1. On your file system, delete the .idea folder, if present, at the top level of your project.

   2. In the Android tool window, open app > res > values > strings.xml.

      In the <string name="app_name"> element, change the text content to Display a web scene.

      strings.xml

      Use dark colors for code blocks

           

      Change line

      1
      2
      3
      4
      5
      <resources>
      
          <string name="app_name">Display a web scene</string>
      
      </resources>

   3. In the Android tool window, open Gradle Scripts > settings.gradle.

      Change the value of rootProject.name to "Display a web scene".

      settings.gradle

      Use dark colors for code blocks

         

      Change line

      1
      2
      3
      include ':app'
      
      rootProject.name = "Display a web scene"

   4. Click File > Sync Project with Gradle files. Android Studio will recognize your changes and create a new .idea folder.

3. If you downloaded the Display a scene solution project, get your API key and set it in your app.

   More info

   An API Key enables access to services, web maps, and web scenes hosted in ArcGIS Online.

   1. Go to your developer dashboard to get your API key. For these tutorials, use your default API key. It is scoped to include all of the services demonstrated in the tutorials.

   2. In Android Studio: in the Android tool window, open app > java > com.example.app > MainActivity.

   3. In the setApiKeyForApp() method, find the ArcGISRuntimeEnvironment.setApiKey("YOUR_API_KEY") call and paste your API key inside the quotes, replacing YOUR_API_KEY.

Prepare files before coding the app

Modify the files from the Display a scene tutorial so that you can use them in this tutorial: you will add imports, change the application title, and remove unnecessary code.

1. In the Android Studio, in the Android tool window, open app > java > com.example.app and then click MainActivity. Add the following imports, replacing those from the Display a scene tutorial.

   MainActivity.kt

   Use dark colors for code blocks

2. In start(), delete the code for base surface, surface elevation, camera, and camera viewpoint. The web scene defines these characteristics, so you don't have to set them in your app.

           // add an exaggeration factor to increase the 3D effect of the elevation.
           surface.elevationExaggeration = 2.5f
   
           scene.baseSurface = surface
   
           // Point(x, y, z, spatialReference)
           val cameraLocation = Point(-118.794, 33.909, 5330.0, SpatialReferences.getWgs84())
           // Camera(location, heading, pitch, roll)
           val camera = Camera(cameraLocation, 355.0, 72.0, 0.0)
   
           sceneView.setViewpointCamera(camera)
   
       }
   
   }
   

3. In start(), delete the code that creates an ArcGISScene by passing a basemap. In this tutorial, you will pass a portal item instead.

Get the web scene item ID

You can use ArcGIS tools to create and view web scenes. Use the Scene Viewer to identify the web scene item ID. This item ID will be used later in the tutorial.

1. Go to the LA Trails and Parks web scene in the Scene Viewer in ArcGIS Online. This web scene displays trails, trailheads and parks in the Santa Monica Mountains.
2. Make a note of the item ID at the end of the browser's URL.

   The item ID should be 579f97b2f3b94d4a8e48a5f140a6639b

Display the web scene

You can display a web scene using the web scene's item ID. Create a scene from the web scene portal item, and display it in your app.

1. In the setupScene() method, create a new Portal referencing ArcGIS Online as the portalUrl parameter and false for the loginRequired parameter.
