Install the Android RUM agent for Splunk RUM ๐Ÿ”—

You can instrument your Android applications for Splunk RUM using the Android RUM agent from the Splunk OpenTelemetry Instrumentation for Android.

To instrument your Android application and get data into Splunk RUM, follow the instructions on this page.


Splunk APM is not required to instrument Splunk RUM for Android.

Decide which version to run in your environment ๐Ÿ”—

Latest updates automatically whenever Splunk RUM releases a new version. In pre-production, use latest to try out the most recent version of Splunk RUM. In production environments, use the pinned version which was previously tested in pre-production and update the production version on a monthly cycle.

Check compatibility and requirements ๐Ÿ”—

Splunk RUM for Mobile supports Java and Kotlin applications for Android API Level 21 and higher. API levels 21 to 25 require core library desugaring activated. See Activate desugaring in your application.

Activate desugaring in your application ๐Ÿ”—

To instrument applications that run on Android API levels 21 to 25, you must activate desugaring.

To activate desugaring in your application, open the build.gradle file for your app module and update the compileOptions and dependencies sections as in the following examples:

android {
   compileOptions {
      coreLibraryDesugaringEnabled = true
      sourceCompatibility = JavaVersion.VERSION_1_8 // Java 8 and higher
      targetCompatibility = JavaVersion.VERSION_1_8 // Java 8 and higher

dependencies {

Save and sync your project to implement desaguring in your application.


Make sure that your Android Gradle plugin is version 4.0.0 and higher.

Install the Android agent as a dependency ๐Ÿ”—

To activate the agent, you must install the Android RUM agent as a code-level dependency in your Android application.

Follow these steps to install the Android RUM agent using Maven Central:

  1. Make sure Maven Central is in the repositories section of your main build.gradle file:

    allprojects {
       repositories {
  2. Add the latest Android RUM agent release as a dependency in the build.gradle file of your application:

    dependencies {
       // Set the desired version of the RUM agent.
       // See available releases:
  3. Configure and initialize the Android RUM agent by passing a configuration object to the initialization call in Application.onCreate():

    import com.splunk.rum.SplunkRum
    import com.splunk.rum.StandardAttributes
    import io.opentelemetry.api.common.Attributes
    class MyApplication extends Application {
       private final String realm = "<realm>";
       private final String rumAccessToken = "<your_RUM_access_token>";
       public void onCreate() {
                   .setDeploymentEnvironment("<name_of_env>") // Environment
                         Attributes.builder() // Add the application version. Alternatively, you
                            // can pass BuildConfig.VERSION_NAME as the value.
                            .put(StandardAttributes.APP_VERSION, "<version_of_app>")
                   // Turn off instrumentation of background processes
                   // Activates debug logging if needed
    • The value passed to .realm() is the Splunk Observability Cloud realm, for example, us0. To find the realm name of your account, follow these steps:

      1. Open the navigation menu in Splunk Observability Cloud.

      2. Select Settings.

      3. Select your username.

      The realm name appears in the Organizations section.

    • To generate a RUM access token, see Generate your RUM access token in Splunk Observability Cloud.

  4. Instrument your HTTP client. For example, the following snippets instruments OkHttp:

    private fun buildOkHttpClient(splunkRum: SplunkRum): Call.Factory {
       return splunkRum.createRumOkHttpCallFactory(OkHttpClient())

    See HTTP instrumentation settings for more information.

  5. Release the changes to the Android application.

  6. Generate some user activity in your application. After youโ€™ve interacted with the application, verify that the data is appearing in the RUM dashboard.


    You can check whether the Android RUM agent has been initialized by calling the SplunkRum.isInitialized() method anywhere in your code.

For a sample application using Android RUM, see the sample application in GitHub .

Build the Android RUM library locally ๐Ÿ”—

To download and build the Android RUM library locally, follow these steps:

  1. Clone the repository to your machine:

    git clone
  2. Build locally and publish to your local Maven repository:

    ./gradlew publishToMavenLocal
  3. Make sure to set mavenLocal() as the repository in your build.gradle file:

    allprojects {
       repositories {
  4. Add the library youโ€™ve built as a dependency in the build.gradle file:

    dependencies {
          implementation ("com.splunk:splunk-otel-android:<version>")

Instrument Android WebViews using the Browser RUM agent ๐Ÿ”—

You can use Mobile RUM instrumentation and Browser RUM instrumentation simultaneously by sharing the splunk.rumSessionId between both instrumentations to see RUM data combined in one stream.

The following snippet shows how to integrate Android RUM with Splunk Browser RUM:

import android.webkit.WebView
import com.splunk.rum.SplunkRum

Make sure that the WebView instance only loads pages under
your control and instrumented with Splunk Browser RUM. The
integrateWithBrowserRum() method can expose the splunk.rumSessionId
of your user to every site/page loaded in the WebView instance.
override fun onViewCreated(view: View, @Nullable savedInstanceState: Bundle?) {
   super.onViewCreated(view, savedInstanceState)
   binding.webView.addJavascriptInterface(WebAppInterface(getContext()), "Android")

Change attributes before theyโ€™re collected ๐Ÿ”—

To remove or change attributes in your spans, such as personally identifiable information (PII), see Filter spans.

How to contribute ๐Ÿ”—
