Prerequisites

Steps

Create a new Java project with Gradle

1. Open IntelliJ IDEA.

2. From the Welcome to IntelliJ IDEA screen, click the New Project button. (If you’re already inside a project, click File > New > Project in the menu bar.)

3. In the New Project window, do the following:

   • Enter a name for your new project and choose a location to save it. Your app name can contain only Latin characters, digits, _ , - and :.

   • Deselect Create Git repository, if necessary

   • Select Java as your programming language, if necessary

   • Select Gradle as your build system

   • Select a supported JDK

   • Select Groovy as your Gradle build language (i.e. DSL), if necessary

   • Check the Add sample code box, if necessary

   • Click Advanced Settings to expand the drop-down. Set the Gradle distribution to Wrapper and check the Auto-select box for the Gradle version. Optionally, you can enable or disable the ability to use these settings for future projects. For GroupId enter com.example.app. You can leave the default for ArtifactId.

   • Click Create to build your new project.

4. In the Project tool window, replace the contents of the build.gradle file with the following script to configure your app and reference the API. Make sure that you load the gradle changes after modifying build.gradle.

   More info

   To load the Gradle changes, in the Gradle window, click the Reload All Gradle Projects icon in the upper left corner.

   

   build.gradle

   plugins {
       id 'application'
       id 'org.openjfx.javafxplugin' version '0.1.0'
       id 'idea'
   }
   
   idea {
       module {
           downloadJavadoc = true
       }
   }
   
   ext {
       arcgisVersion = '200.6.0'
   }
   
   repositories {
       mavenCentral()
       maven {
           url 'https://esri.jfrog.io/artifactory/arcgis'
       }
   }
   
   configurations {
       natives
   }
   
   dependencies {
       implementation "com.esri.arcgisruntime:arcgis-java:$arcgisVersion"
       natives "com.esri.arcgisruntime:arcgis-java-jnilibs:$arcgisVersion"
       natives "com.esri.arcgisruntime:arcgis-java-resources:$arcgisVersion"
       implementation 'org.slf4j:slf4j-nop:2.0.16'
   }
   
   javafx {
       version = "21.0.5"
       modules = [ 'javafx.controls', 'javafx.graphics', 'javafx.fxml', 'javafx.web', 'javafx.media' ]
   }
   
   application {
       mainModule = "com.example.app"
       mainClass = "com.example.app.App"
   }
   
   task copyNatives(type: Copy) {
       description = "Copies the arcgis native libraries into the .arcgis directory for development."
       group = "build"
       configurations.natives.asFileTree.each {
           from(zipTree(it))
       }
       into "${System.properties.getProperty("user.home")}/.arcgis/$arcgisVersion"
   }
   
   run {
       dependsOn copyNatives
   }
   
   wrapper {
       gradleVersion = '8.10.2'
   }

5. Click View > Tool Windows > Gradle to open the Gradle view, then in Tasks > build, double-click copyNatives. This unpacks the native library dependencies to $USER_HOME/.arcgis.

   More info

   You can also run Gradle tasks via the command line. Consult Gradle’s documentation to learn how this is done.

6. In the Project tool window, under your package com.example.app, right-click Main and click Refactor > Rename….

7. Rename the Java class to App and click Refactor.

Add a UI for the map view

A map view A map view is a user interface that displays map layers and graphics in 2D. It controls the area (extent) of the map that is visible and supports user interactions such as pan and zoom. Learn more is a UI component that displays a map A map is a collection of layers that are displayed in 2D. It is typically composed of a basemap layer and data layers. Learn more . It also handles user interactions with the map. Use JavaFX to add a map view to the UI.

1. In App.java, define a class named App that extends the JavaFX Application class.

   • Add a private member variable with type MapView.

     More info

     The mapView member variable allows you to easily reference your MapView from other parts of the application.

   • Inside the main() method, replace the print statement with a call to Application.launch(args).

     More info

     This code calls the static method launch() of the JavaFX class Application, which creates an instance of your App class on the JavaFX Application Thread and then calls the start() method. For a description of the JavaFX life-cycle, see Application.

   • Override the start() method, in which you configure the JavaFX Stage with a title and dimensions, and then show it.

     More info

     Note that the start() method is abstract in the JavaFX Application class and must be overridden in your application code. The start() method takes a single parameter of the JavaFX type Stage.

   • Create a JavaFX StackPane and use it to create a JavaFX Scene. Then set the scene on the stage.

   Provide latitude and longitude coordinates and a scale value as parameters to a new Viewpoint. Then set it on the mapView with setViewpoint().

   More info

   The Viewpoint(double,double,double) constructor used in this tutorial takes a scale parameter. The scale value 144447.638572 is converted from zoom level 12. Zoom levels are often used as a shorthand for predetermined scale values in Web Mercator maps. Learn more in Zoom levels and scale.

Get an access token

You need an access token An 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 to use the location services ArcGIS Location Services, also referred to as Location Services, are services hosted by Esri that provide geospatial functionality for developing mapping applications. They include the ArcGIS Basemap Styles service, ArcGIS Static Basemap Tiles service, ArcGIS Places service, ArcGIS Geocoding service, ArcGIS Routing service, ArcGIS GeoEnrichment service, and ArcGIS Elevation service. An ArcGIS Location Platform or ArcGIS Online account is required to use the services. Learn more used in this tutorial.

1. Go to the Create an API key tutorial to obtain an access token An 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 Platform An 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 Online An 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.

2. Ensure that the following privilege Privileges 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.

3. Copy the access token as it will be used in the next step.

To learn more about other ways to get an access token, go to Types of authentication.

Set your API key

Set the API key property on the ArcGISRuntimeEnvironment. In the code below, replace YOUR_ACCESS_TOKEN with your copied access token. Be sure to surround your access token with double quotes as it is a string.

Modularize the app

A Java module adds a higher level of aggregation above packages. A module must provide a module descriptor that specifies the dependencies, the packages the module makes available to other modules, and more.

You will create the module descriptor for this project in a file named module-info.java.

1. In the Project tool window, under src/main, right-click the java folder, and click New > module-info.java.

2. Inside module-info.java replace the module name (i.e. highlighted text) with com.example.app.

3. In the body of the module descriptor, define the three required packages this application depends on: com.esri.arcgisruntime, javafx.graphics, and org.slf4j.nop.

4. Export this project’s module package to make it accessible to code in all other modules.

You should see a map A map is a collection of layers that are displayed in 2D. It is typically composed of a basemap layer and data layers. Learn more with the topographic basemap layer A basemap layer is the layer in a map or scene that displays basemap data. The data source for a basemap layer is typically a basemap service. Learn more centered on the Santa Monica Mountains in California. Click, drag, and scroll the mouse wheel on the map view to explore the map.
