Android (Kotlin)

The Confidence Android SDK provides feature flag evaluation for Android applications. Flags resolve once according to the evaluation context, and values read from a local cache for fast access.

Features

Local caching: Flag values cached locally for instant access
OpenFeature compatible: Standard feature flag API through OpenFeature provider
Automatic apply events: Tracks flag assignments when your application reads flags
Custom event tracking: Sends application events through the OpenFeature Tracking API
Managed context: Automatic visitor ID and opt-in device information context
Offline support: Cached values available without network

Automatic apply events record flag assignments without explicit tracking calls. Custom tracking events are separate and require a call to the OpenFeature client’s track method.

Installation

Gradle (Kotlin DSL)
Gradle (Groovy)

dependencies {
    implementation("com.spotify.confidence:openfeature-provider-android:<latest>")
}

dependencies {
    implementation 'com.spotify.confidence:openfeature-provider-android:<latest>'
}

Quickstart

import com.spotify.confidence.ConfidenceFactory
import com.spotify.confidence.ConfidenceFeatureProvider
import com.spotify.confidence.ConfidenceRegion
import com.spotify.confidence.InitialisationStrategy
import dev.openfeature.sdk.OpenFeatureAPI

// Create the Confidence provider
val provider = ConfidenceFeatureProvider.create(
    ConfidenceFactory.create(
        context = applicationContext,
        clientSecret = "your-client-secret",
        region = ConfidenceRegion.EUROPE
    ),
    initialisationStrategy = InitialisationStrategy.FetchAndActivate
)

// Register with OpenFeature
OpenFeatureAPI.setProviderAndWait(provider)
val client = OpenFeatureAPI.getClient()

// Evaluate a flag
val message = client.getStringValue("flag-name.message", "default message")
println("Flag value: $message")

// Track a custom application event
client.track("checkout")
