Its JSON structure is defined by the web scene specification.Learn more. All web scenes are stored in ArcGIS with a unique item IDAn item ID is a unique identifier representing a single item stored, managed, and accessed in a portal, such as a web map, hosted layer, or file.Learn more. You will access an existing web scene by item ID and display its layers. The web scene contains feature layersA feature layer (client-side) is a data layer that can access and display features from a feature service that has the same type of geometry and attribute fields.Learn more for the Santa Monica Mountains in California.

Prerequisites

Steps

Open a Java project with Gradle

1. To start the tutorial, complete the Display a scene tutorial, or download and unzip the Display a scene solution into a new folder.

2. Open the build.gradle file as a project in IntelliJ IDEA.

3. If you downloaded the solution, get an access token and set the API key.

   More info

   An API keyAn API key is a long-lived access token created using API key credentials. They are valid for up to one year and are typically embedded directly into client applications.Learn more gives your app access to secure resourcesA secure resource is any item or service in an ArcGIS that requires an ArcGIS account and authentication to access. Examples include ArcGIS Location Services, and items and data services in an ArcGIS portal.Learn more used in this tutorial.

   1. Go to the Create an API key tutorial to obtain a new API key access tokenAn access token is an authorization string that provides access to secure ArcGIS content, data, and services. Its capabilities are determined by the privileges it supports. It is obtained by implementing API key authentication, User authentication, or App authentication.Learn more using your ArcGIS Location PlatformAn ArcGIS Location Platform account, formerly known as an ArcGIS Developer account, is an identity associated with an ArcGIS Location Platform subscription.Learn more or ArcGIS OnlineAn ArcGIS Online account, also known as an ArcGIS Organization account, is an identity associated with an ArcGIS Online subscription. It can be used to access ArcGIS tools and develop applications with ArcGIS location services for an organization.Learn more account. Ensure that the following privilegePrivileges are a set of permissions assigned to ArcGIS accounts, developer credentials, and applications that grant access to secure resources and functionality in ArcGIS.Learn more is enabled: Location services > Basemaps > Basemap styles service. Copy the access token as it will be used in the next step.

   2. In the IntelliJ IDEA > Project tool window, open src/main/java/com.example.app and double-click App.

   3. In the start() method, set the API key property on the ArcGISRuntimeEnvironment with your access tokenAn access token is an authorization string that provides access to secure ArcGIS content, data, and services. Its capabilities are determined by the privileges it supports. It is obtained by implementing API key authentication, User authentication, or App authentication.Learn more. Replace YOUR_ACCESS_TOKEN with your copied access token. Be sure to surround your access token with double quotes as it is a string.

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.

1. In IntelliJ IDEA's Project tool window, open src/main/java/com.example.app and double-click App.

2. Add the following imports, replacing those from the Display a scene tutorial.
