Group Presence package

Updated: Sep 4, 2026

The Platform SDK Group Presence Package enables users to see which friends are in joinable areas of applications and facilitates social discovery and joining. The package sets and clears user presence in joinable destinations within applications, indicating when users are in areas that support multiplayer interaction.

Friends can see presence status and join directly into these shared experiences. This functionality is currently supported only for immersive mode applications, not for 2D panel apps, and is essential for social VR experiences and multiplayer games.

Before you begin

Complete the prerequisite steps in Get Started Kotlin Development.

How to install

Add the following to your project’s ./gradle/libs.versions.toml file:

 [libraries]
 # Existing lines
 group-presence-kotlin = { module = "com.meta.horizon.platform.sdk:group-presence-kotlin", version.ref = "horizonPlatformSdk" }

 dependencies {
     // Existing lines
     implementation(libs.group.presence.kotlin)
 }

In Android Studio, click File > Sync Project with Gradle Files to install the package.
Click Build > Generate App Bundles or APKs > Generate APKs.
In the “External Libraries” section of your project, confirm that these packages are listed.
```
 com.meta.horizon.platform.sdk:core-kotlin
 com.meta.horizon.platform.sdk:group-presence-kotlin
```
Now you can initialize the Platform SDK and use Group Presence package functions in your app.

Test this on Meta Spatial Simulator

Group Presence behaves differently depending on which API you call. The panel and dialog APIs, such as launchInvitePanel and launchRejoinDialog, open a simulated dialog — launchRejoinDialog also persists the presence state you confirm:
