OpenFeature Provider (Android)

Overview

The Mixpanel OpenFeature provider allows you to use Mixpanel Feature Flags through the standardized OpenFeature API. This provider wraps the Mixpanel Android SDK’s MixpanelAPI.Flags, letting you use the OpenFeature Kotlin SDK with Mixpanel as the backend.

For the core Feature Flags SDK guide, see Feature Flags (Android).

Prerequisites

• You are on an Enterprise subscription plan
• You have the Mixpanel Android SDK installed
• You have your Project Token from your Mixpanel Project Settings

Installation

Add the OpenFeature provider and SDK to your build.gradle:

dependencies {
    implementation 'com.mixpanel:mixpanel-android-openfeature-provider:1.0.0'
    implementation 'dev.openfeature:android-sdk:0.3.0'
}

Usage

The provider wraps MixpanelAPI.Flags from the Mixpanel Android SDK.

import com.mixpanel.android.mpmetrics.MixpanelAPI
import com.mixpanel.openfeature.MixpanelProvider
import dev.openfeature.sdk.OpenFeatureAPI
 
// Initialize Mixpanel
val mixpanel = MixpanelAPI.getInstance(context, "YOUR_PROJECT_TOKEN")
 
// Register the OpenFeature provider
val provider = MixpanelProvider(mixpanel.flags)
OpenFeatureAPI.setProvider(provider)
 
val client = OpenFeatureAPI.getClient()
val showNewUI = client.getBooleanValue("new-ui", false)

Supported Flag Types

Context and Identity

• targetingKey has no special meaning in this provider. It is treated as a regular context property.
• Identity should be managed through the Mixpanel SDK via mixpanel.identify().

Error Handling

The provider returns the default value on all errors, with an error code indicating the cause:

Use getDetails() methods instead of getValue() to inspect error codes:

val details = client.getBooleanDetails("my-flag", false)
if (details.errorCode != null) {
    Log.d("Flags", "Flag error: ${details.errorCode} - ${details.errorMessage}")
}

Lifecycle

• shutdown() is a no-op. The Mixpanel SDK manages its own lifecycle.
• The reason code for successful evaluations is STATIC.
