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 feature layers for the Santa Monica Mountains in California.
Prerequisites
The following are required for this tutorial:
An ArcGIS account to access your API keys. If you don't have an account, sign up for free.
To start the tutorial, complete the Display a scene tutorial, or download and unzip the Display a scene solution into a new folder.
Open the build.gradle file as a project in IntelliJ IDEA.
If you downloaded the solution project, set your API key.
An API Key enables access to services, web maps, and web scenes hosted in ArcGIS Online.
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.
In the IntelliJ IDEA > Project tool window, open src/main/java/com.example.app and click App.
In the start() method, set the API key property on the ArcGISRuntimeEnvironment with your API key. Replace YOUR_API_KEY with your actual API Key. Be sure to surround your API Key with quotes, because the parameter passed to setApiKey is a string.

// Note: it is not best practice to store API keys in source code.// The API key is referenced here for the convenience of this tutorial. String yourApiKey = "YOUR_API_KEY";
ArcGISRuntimeEnvironment.setApiKey(yourApiKey);

Prepare files before coding the app
Modify the files from the Display a scene tutorial so that they can be used in this tutorial: you will add imports, change the application title, and remove unnecessary code.
In IntelliJ IDEA's Project tool window, open src/main/java/com.example.app and double-click App.
Add the following imports, replacing those from the Display a scene tutorial.
In the start() life-cycle method, change the title that will appear on the application window to Display a web scene tutorial.

In start() method, 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.

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.
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.
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.
In the start() method, create a new Portal(java.lang.String,boolean) referencing ArcGIS Online as the portalUrl parameter and false for the loginRequired parameter.

Create a PortalItem for the web scene by passing the portal and the web scene's item ID as parameters.

Run the app. Ensure to run the app as a Gradle task and not as an application in your IDE. In the Gradle tool window, under Tasks > application, double-click run.
Your app should display the scene that you viewed earlier in the Scene Viewer.
