Add a feature layer from a portal item | ArcGIS Maps SDK for Kotlin

Learn how to use an ArcGIS portal item to access and display a feature layer A 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 in 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 .

add a feature layer from a portal item

You can host a variety of geographic data and other resources using ArcGIS Online ArcGIS Online is a GIS mapping, analytics, data hosting, and content management software as a service (SaaS) product. It includes applications, tools, APIs, and location services for users and developers. It is subscription-based and requires an ArcGIS Online account. Learn more . These portal items An item, also known as a content item, is a resource stored in a portal such as a web map, hosted layer, style, script tool, file, or notebook. Learn more can also define how the data is presented. A web map A web map is a map stored as a JSON object that defines properties such as the basemap layer, data layers, layer styles, and pop-up styles. Its JSON structure is defined by the web map specification. Learn more or web scene A web scene is a scene stored as a JSON object that defines properties such as the basemap layer, data layers, layer styles, and pop-up styles. Its JSON structure is defined by the web scene specification. Learn more , for example, not only defines the layers for 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 or scene A scene is a collection of layers that are displayed in 3D. It is typically composed of a basemap layer, data layers, and 3D data. Learn more , but also how layers are symbolized, the minimum and/or maximum scales at which they display, and several other properties. Likewise, a hosted feature layer contains the data for the layer and also defines the symbols and other display properties for how it is presented. When you add a map, scene, or layer from a portal item to your app, everything that has been saved with the item An item, also known as a content item, is a resource stored in a portal such as a web map, hosted layer, style, script tool, file, or notebook. Learn more is applied in your app. Adding portal items to your app rather than creating them programmatically saves you from writing a lot of code, and can provide consistency across apps that use the same data.

In this tutorial, you will add a hosted feature layer to display trailheads in the Santa Monica Mountains of Southern California. The hosted layer defines the trailhead locations (points) as well as the symbols used to display them.

Prerequisites

Before starting this tutorial, you need the following:

An ArcGIS Location Platform or ArcGIS Online account.
A development and deployment environment that meets the system requirements.
An IDE for Android development in Kotlin.

Develop or download

You have two options for completing this tutorial:

Option 1: Develop the code or
Option 2: Download the completed solution

Option 1: Develop the code

Open an Android Studio project with Gradle

Open the project you created by completing the Display a map tutorial.
Continue with the following instructions to use an ArcGIS portal item to access and display a feature layer in a map.

Modify the old project for use in this new tutorial.

On your file system, delete the .idea folder, if present, at the top level of your project.
In the Android view, open app > res > values > strings.xml.

In the <string name="app_name"> element, change the text content to Add a feature layer from a portal item.
strings.xml
<resources> <string name="app_name">Add a feature layer from a portal item</string> </resources>

In the Android view, open Gradle Scripts > settings.gradle.kts.

Change the value of rootProject.name to “Add a feature layer from a portal item”.

include(":app")

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

Add import statements

In the Android view, open app > kotlin+java > com.example.app > MainScreen.kt. Replace the import statements with the imports needed for this tutorial.

Add a feature layer to the map

You can reference an item An item, also known as a content item, is a resource stored in a portal such as a web map, hosted layer, style, script tool, file, or notebook. Learn more (such as a web map or feature layer) hosted in a portal (such as ArcGIS Online) using its unique item ID An 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 reference the Trailheads Styled feature layer stored in ArcGIS Online using its item ID: 2e4b3df6ba4b44969a3bc9827de746b3. You will then add that feature layer to your map’s collection of data layers (operational layers).

In MainScreen, before the code that creates the ArcGISMap, create a new Portal referencing ArcGIS Online as the url parameter and Portal.Connection.Anonymous for the connection parameter.

Alternatively, you can download the tutorial solution, as follows.

Option 2: Download the solution

Click the Download solution link in the right-hand side of this page.
Unzip the file to a location on your machine.
Run Android Studio.
Go to File > Open…. Navigate to the solution folder and click Open.

On Windows: If you are in the Welcome to Android Studio dialog, click Open and navigate to the solution folder. Then click Open.

Since the downloaded solution does not contain authentication credentials, you must first set up authentication to create credentials, and then add the developer credentials to the solution.

Set up authentication

To access the secure ArcGIS 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.

Copy and paste the API key access token into a safe location. It will be used in a later step.

Create new OAuth credentials to access the secure resources used in this tutorial.

Complete the Create OAuth credentials for user authentication tutorial to obtain a Client ID and Redirect URL.

A Client ID uniquely identifies your app on the authenticating server. If the server cannot find an app with the provided Client ID, it will not proceed with authentication.
The Redirect URL (also referred to as a callback url) is used to identify a response from the authenticating server when the system returns control back to your app after an OAuth login. Since it does not necessarily represent a valid endpoint that a user could navigate to, the redirect URL can use a custom scheme, such as my-app://auth. It is important to make sure the redirect URL used in your app’s code matches a redirect URL configured on the authenticating server.
Copy and paste the Client ID and Redirect URL into a safe location. They will be used in a later step.

Best Practice: The access token is stored directly in the code as a convenience for this tutorial. Do not store credentials directly in source code in a production environment.

In the Android view of Android Studio, open app > kotlin+java > com.example.app > MainActivity. Set the AuthenticationMode to .USER_AUTH.

MainActivity.kt

class MainActivity : ComponentActivity() {
    private enum class AuthenticationMode { API_KEY, USER_AUTH }

    private val authenticationMode = AuthenticationMode.USER_AUTH

Set your clientID and redirectURL values. You must use the RedirectURL that you supplied for your app in the user authentication part of the Set up authentication step.

MainActivity.kt

            AuthenticationMode.USER_AUTH -> {
                authenticatorState.oAuthUserConfigurations = listOf(
                    OAuthUserConfiguration(
                        portalUrl = "https://www.arcgis.com",

                        clientId = "YOUR_CLIENT_ID",
                        redirectUrl = "YOUR_REDIRECT_URL"

                    )
                )

Open app > manifests > AndroidManifest.xml.

Set the android:scheme and android:host using the scheme and host from your RedirectURL.
