Install and set up

Before installing ArcGIS Maps SDK for Kotlin, make sure your development machine meets the system requirements. A minimum Android API version is required for any target device on which your app will run. For more information, see system requirements.

We recommend installing with Gradle, which will install the needed dependencies and SDK binaries from Esri's Maven repository.

Get the API with Gradle

Perform the following set up steps in an existing Android Studio project, or create a new project.

1. In your settings.gradle file, within the repositories block of the dependencyResolutionManagement block, add a maven block and specify the URL of Esri's Maven repository. Esri's repository is not open source and therefore not available from google() or mavenCentral(), so you must specify this URL.

           mavenCentral()
           maven {
               url 'https://esri.jfrog.io/artifactory/arcgis'
           }
       }
   }

2. In your module-level build.gradle file, within the dependencies block, add the ArcGIS Maps SDK for Kotlin dependency to your app.

       implementation 'com.esri:arcgis-maps-kotlin:200.1.0'
   }

3. In your module-level build.gradle file, within the android block, make sure you have a buildFeatures block that enables view binding or data binding. For more information on view binding, see https://developer.android.com/topic/libraries/view-binding. For more information on data binding, see https://developer.android.com/topic/libraries/data-binding/start.

       // buildFeatures {
       //     dataBinding true
       // }
       . . .
   }

4. In your module-level build.gradle file, within the android block, make sure you have a packagingOptions block that excludes duplicates of the META-INF\DEPENDENCIES file. This setting will prevent a compiler error that occurs if you try to include the same file in the META-INF directory more than once in the output. For more information on packaging options, see https://developer.android.com/reference/tools/gradle-api/7.4/com/android/build/api/dsl/PackagingOptions.

Required permissions and features

Android is a permissions-separated operating system. Depending on which ArcGIS capabilities you use in your app, you may need to add permissions to your manifest. Make sure that you do not include permissions for capabilities that are not included in your app.

If an app is running on Android API version 22 or earlier, all permissions are requested (and granted or denied), at installation time. If an app is running on Android API version 23 or newer, permissions are requested and automatically granted at installation time. Potentially dangerous permissions, however, must be requested at run time, and you need to add code to your app to do so. The Android framework or Android Support library is used to check for and request permissions if not already granted. For more information, see Declaring Permissions and Requesting Permissions at Run Time.

ArcGIS Maps SDK for Kotlin capabilities requiring permissions

Some of the capabilites of ArcGIS Maps SDK for Kotlin that you use in your app require Android permissions.

• Access to the Internet (most apps will require this): normal permission in Android API 23 and newer.
• Access to the device's GPS will require fine location permissions: dangerous permission in Android API 23 and newer.

The following code example (for the AndroidManifest.xml file) includes these permissions:

1
2
3
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

Android storage and permissions

As of Android API Level 30, all apps use scoped storage for accessing the file system of the Android device. With scoped storage, an app can access (1) its own files and (2) shared files in a media store. Declaring the <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> permission is no longer supported.

Storage in Android has changed dramatically since API level 29. Consult the following links to learn more about Android storage and permissions:

• Data and file storage overview
• Android storage use cases and best practices
• Access media files from shared storage
• Manage all files on a storage device

Declaring OpenGL ES version

Adding a uses-feature element to the Android manifest will help the Play store make your app available to the correct type of devices.

Apps that use a MapView (2D) require at least OpenGL ES 2.x:

1
<uses-feature android:glEsVersion="0x00020000" android:required="true" />

Apps that use a SceneView (3D) require OpenGL ES 3.x:

1
<uses-feature android:glEsVersion="0x00030000" android:required="true" />

Additional downloads

Additional sources of sample code and data are available to enhance your development projects. You can even download this guide as stand-alone developer documentation.

Sample code

Browse the comprehensive list of samples in the documentation or download sample code from the GitHub repository.

Stand-alone developer documentation

You can download the developer documentation as an archive from the downloads page. The archive contains instructions to serve the documentation from a local web server so you can access it without a connection to the internet. The stand-alone documentation includes the developer guide, API reference, tutorials, and samples documentation. This documentation is designed to run on a local stand-alone computer or on an internal network and not on the public internet.

To serve the documentation locally:

• Download the documentation for the SDK you want to use. The downloaded files are in a .zip archive format.
• Extract the archive to a local folder. The extracted archive has two subfolders: public and install.
• Open the README.md file in the install folder and follow the instructions for your chosen web server.

Supplemental data

StreetMap Premium

StreetMap Premium for ArcGIS Runtime SDKs and ArcGIS Maps SDKs for Native Apps provides enriched street data, which powers a high-quality cartographic maps and high-quality search, geocoding, and route analysis. StreetMap Premium maps are consistent across all regions of the world and can be taken offline for disconnected use; they can simultaneously fulfill the need for an address locator, street network dataset, and basemap in your app.

If you want to use StreetMap Premium data (the StreetMap Premium extension), download the demonstration data from the downloads page for development and testing. Please contact Esri Customer Service for access to a region of your choice for development and testing or to license StreetMap Premium data for deployment.

Projection Engine data

Datum transformations are used when geometries must be projected from one spatial reference to another when there is a difference in the datum that underlies the two spatial references. Datum transformations can be mathematically defined (equation-based transformations), or may rely on external supporting files (grid-based transformations). Certain Projection Engine data files must be present when you use a grid-based transformation in your app; attempting to use a transformation with missing Projection Engine files will cause an error. The API can detect whether the necessary files are available on the local file system.

If your app requires grid-based transformations, you can download supporting Projection Engine files from the downloads page. See the Spatial references topic for more information about working with coordinate systems, projections, and datum transformations.

Electronic Navigational Charts (ENC)

Electronic navigational charts (ENCs) are georeferenced vector datasets for the visualization and analysis of hydrographic and maritime information. This SDK supports ENCs that conform to the International Hydrographic Organization (IHO) S-57 standard.

If you want to work with Electronic Navigational Charts (ENC) download the hydrography directory from the downloads page.

See the Display electronic navigational charts topic for more information about working with ENC data.
