Add a point, line, and polygon | ArcGIS Maps SDK for Kotlin

Learn how to display point, line, and polygon graphics A graphic is a visual element composed of a geometry, symbol, and attributes that is displayed on a map or scene. 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 point line and polygon

You typically use graphics A graphic is a visual element composed of a geometry, symbol, and attributes that is displayed on a map or scene. Learn more to display geographic data that is not connected to a database and that is not persisted, like highlighting a route between two locations, displaying a search buffer around a selected point, or showing the location of map coordinates entered by the user. Graphics are composed of a geometry A geometry is a geometric shape, such as a point, polyline, or polygon, that contains one or more coordinates and a spatial reference. Learn more , symbol A symbol defines the properties used to display a geometry or text. Learn more , and attributes Attributes are fields and values for a single feature or non-spatial record. They are typically stored in a database or service such as a feature service. Learn more .

In this tutorial, you display points, lines, and polygons on a map as graphics A graphic is a visual element composed of a geometry, symbol, and attributes that is displayed on a map or scene. Learn more .

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

Open the project you created by completing the Display a map tutorial.
Continue with the following instructions to display a point, line, and polygon in the 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 point, line, and polygon.
strings.xml
<resources> <string name="app_name">Add a point, line, and polygon</string> </resources>

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

Change the value of rootProject.name to “Add a point, line, and polygon”.

Add a graphics overlay and a list of graphics overlay

You will create a GraphicsOverlay. Then add the graphics overlay to a list named graphicsOverlays.

For information about remembering state between recompositions in Android Jetpack Compose, see State and Jetpack Compose.

In subsequent sections of this tutorial, you will create a point, a line, and a polygon and add each of them to the GraphicsOverlay.

In the MainScreen composable, add a remember block and create a GraphicsOverlay inside it. Then assign remember to a local variable named graphicsOverlay.

Add a point graphic

A point graphic A graphic is a visual element composed of a geometry, symbol, and attributes that is displayed on a map or scene. Learn more is created using a point A geometry is a geometric shape, such as a point, polyline, or polygon, that contains one or more coordinates and a spatial reference. Learn more and a marker symbol A symbol defines the properties used to display a geometry or text. Learn more . A point is defined with x and y coordinates, and a spatial reference A spatial reference is a set of parameters, typically defined by a WKID, that define the coordinate system and spatial properties for geographic data. Applications use a spatial reference to correctly display the position of geographic data in a map or scene. Learn more . For latitude and longitude coordinates, the spatial reference is WGS84.

In the lazy block of thepointGraphic property , create a Point and a SimpleMarkerSymbol. To create the point, provide x (longitude) and y (latitude) coordinates and a SpatialReference (by calling wgs84() on SpatialReference).

Point graphics support a number of symbol types such as SimpleMarkerSymbol, PictureMarkerSymbol, and TextSymbol. Learn more about symbols at Symbol in the API Reference.

Assign blueOutlineSymbol to the outline property of simpleMarkerSymbol.

Click Run > Run > app to run the app.

In Android Studio, you have two choices for running your app: an actual Android device or the Android Emulator.

Android device

Connect your computer to your Android device, using USB or Wi-Fi. For more details, see How to connect your Android device.

Android Emulator

Create an AVD (Android Virtual Device) to run in the Android Emulator. For details, see Run apps on the Android Emulator.

Selecting a device

When you build and run an app in Android Studio, you must first select a device. From the Android Studio toolbar, you can access the drop-down list of your currently available devices, both virtual and physical.

Drop-down for available devcies in Android Studio .

If you cannot access the list on the toolbar, click Tools > Device Manager.

You should see a point graphic in Point Dume State Beach.

Add a line graphic

A line graphic A graphic is a visual element composed of a geometry, symbol, and attributes that is displayed on a map or scene. Learn more is created using a polyline A geometry is a geometric shape, such as a point, polyline, or polygon, that contains one or more coordinates and a spatial reference. Learn more and a line symbol A symbol defines the properties used to display a geometry or text. Learn more . A polyline is defined as a sequence of points.

Polylines have one or more distinct parts. Each part is a sequence of points. For a continuous line, you can use the Polyline constructor to create a polyline with just one part. To create a polyline with more than one part, use a PolylineBuilder.

Create a lazy top-level property named polylineGraphic.

In the lazy block, create a Polygon and a SimpleFillSymbol. To create the polygon, create a PolygonBuilder and then call toGeometry() on the polygon builder.

Polygon graphics support a number of symbol types such as SimpleFillSymbol, PictureFillSymbol, SimpleMarkerSymbol and TextSymbol. Learn more about symbols at Symbol in the API Reference.

Next, create a SimpleFillSymbol that has a solid red fill with an alpha channel of 128 and uses the blueOutlineSymbol defined earlier.

In Android Studio, you have two choices for running your app: an actual Android device or the Android Emulator.

Android device

Connect your computer to your Android device, using USB or Wi-Fi. For more details, see How to connect your Android device.

Android Emulator

Create an AVD (Android Virtual Device) to run in the Android Emulator. For details, see Run apps on the Android Emulator.

Selecting a device

Drop-down for available devcies in Android Studio .

If you cannot access the list on the toolbar, click Tools > Device Manager.

You should see a point, line, and polygon graphic around Mahou Riviera in the Santa Monica Mountains.

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.

User authentication User authentication is a type of authentication that allows users with an ArcGIS account to sign into an application and allow it to access ArcGIS content, services, and resources on their behalf. The typical authorization protocol used is OAuth2.0. Learn more

Users are required to sign in with an ArcGIS account An ArcGIS account is an identity with a user type and set of privileges that can access specific ArcGIS products, tools, APIs, services, and resources. The main account types that can be used for development are an ArcGIS Location Platform account, ArcGIS Online account, and ArcGIS Enterprise account. ArcGIS Location Platform and ArcGIS Online accounts are also associated with a subscription. Learn more .
User accounts must have 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 to access the ArcGIS services A service, also known as an ArcGIS service, is software that supports an ArcGIS REST API and provides geospatial functionality or data. A service can be hosted by Esri or in ArcGIS Enterprise. Learn more used in application.
Requires creating OAuth credentials OAuth credentials are an item that contains parameters required to implement user authentication or app authentication, including a client_id, client_secret, and redirect URIs. They are a type of developer credential. Learn more .
Application uses a redirect URL and client ID.
Service usage is billed to the organization of the user signed into the application.

To complete this tutorial, click on the tab in the switcher below for your authentication type of choice, either API key authentication or User authentication.

Create a new API key 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 with privileges 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 to access the secure resources used in this tutorial.

Complete the Create an API key tutorial and create an API key with the following privilege(s) 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 :
- Privileges
  - Location services > Basemaps
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.

All users that access this application need account privileges 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 to access the ArcGIS Basemap Styles service The ArcGIS Basemap Styles service, also referred to as the Basemap Styles service, is a location service that provides basemap styles and data for the world. It returns styles as Mapbox styles and web maps, and data as vector tiles and/or map tiles. It supports all of the styles in the ArcGIS Basemap style and Open Basemap style family. An ArcGIS Location Platform or ArcGIS Online account is required to use the service. Learn more .

Set developer credentials in the solution

To allow your app users to access 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. Learn more , use the developer credentials that you created in the Set up authentication step to authenticate requests for resources.

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.

A redirectURL is composed of a scheme and a host component. The format for the redirect url is scheme://host. For example, if the redirect url is myscheme://myhost then the scheme is myscheme and the host is myhost.
