Founded in 2011, the platform provides tools for tracking user acquisition, engagement, and retention across various marketing channels.

AppsFlyer integrates with a wide array of ad networks, publishers, and marketing partners to provide a unified view of campaign performance.

The platform is suitable for mobile app developers, performance marketers, and data analysts who require detailed visibility into their user journeys. It addresses challenges such as understanding the return on investment (ROI) of marketing spend, identifying high-value users, and mitigating ad fraud. AppsFlyer's fraud protection suite aims to detect and prevent fraudulent installs and post-install events, ensuring data accuracy for optimization efforts AppsFlyer API Integrations documentation.

For developers, AppsFlyer offers comprehensive SDKs for major mobile platforms like iOS and Android, as well as cross-platform frameworks such as Unity, React Native, and Flutter. These SDKs facilitate the integration of attribution and analytics tracking into mobile applications. The platform also supports server-to-server integrations for scenarios requiring more control over data exchange. AppsFlyer emphasizes compliance with data privacy regulations such as GDPR and CCPA, holding certifications like SOC 2 Type II and ISO 27001, which are critical for businesses operating in regulated markets AppsFlyer Compliance information. The company's "Privacy Cloud" initiative further aims to provide a secure environment for data collaboration while adhering to privacy standards.

AppsFlyer's user journey analysis capabilities allow for mapping out how users interact with an app from initial install through subsequent in-app actions. This data can be used to segment audiences, personalize user experiences, and refine targeting strategies. The platform also offers incrementality testing tools to measure the true uplift generated by specific marketing activities, helping marketers make data-driven decisions about budget allocation CXL's guide to incrementality testing. Its deep linking technology ensures users are directed to specific content within an app, improving user experience and conversion rates from marketing campaigns.

Getting started

To integrate AppsFlyer into a new Android application, developers typically add the AppsFlyer SDK to their project and initialize it. The following example demonstrates a basic initialization in an Android Kotlin project, which tracks app opens and can be configured to track additional in-app events.

// In your app's build.gradle (Module: app) file, add the dependency:
// implementation 'com.appsflyer:af-android-sdk:6.10.x'

// In your Application class or main Activity, initialize the SDK
import android.app.Application
import com.appsflyer.AppsFlyerLib
import com.appsflyer.AppsFlyerConversionListener
import com.appsflyer.attribution.AppsFlyerRequestListener

class MyApplication : Application() {

    override fun onCreate() {
        super.onCreate()

        val devKey = "YOUR_APPSFLYER_DEV_KEY"

        AppsFlyerLib.getInstance().init(devKey, object : AppsFlyerConversionListener {
            override fun onConversionDataSuccess(conversionData: MutableMap?) {
                conversionData?.let { data ->
                    for (attrName in data.keys) {
                        // Log conversion data attributes
                        // Log.d("AppsFlyer", "Conversion attribute: $attrName = ${data[attrName]}")
                    }
                }
            }

            override fun onConversionDataFail(errorMessage: String?) {
                // Log error if conversion data fetch fails
                // Log.e("AppsFlyer", "Error getting conversion data: $errorMessage")
            }

            override fun onAppOpenAttribution(attributionData: MutableMap?) {
                // Handle app open attribution data
                // Log.d("AppsFlyer", "onAppOpenAttribution: $attributionData")
            }

            override fun onAttributionFailure(errorMessage: String?) {
                // Log error if attribution fails
                // Log.e("AppsFlyer", "Error getting attribution: $errorMessage")
            }
        }, this)

        AppsFlyerLib.getInstance().start(this, devKey, object : AppsFlyerRequestListener {
            override fun onSuccess() {
                // Log success of SDK start
                // Log.d("AppsFlyer", "AppsFlyer SDK started successfully.")
            }

            override fun onError(errorCode: Int, errorDesc: String) {
                // Log error if SDK fails to start
                // Log.e("AppsFlyer", "AppsFlyer SDK failed to start: $errorDesc (Code: $errorCode)")
            }
        })

        // For debug logging
        // AppsFlyerLib.getInstance().setLogLevel(AFLogger.LogLevel.DEBUG);
    }
}

Replace "YOUR_APPSFLYER_DEV_KEY" with your actual AppsFlyer Dev Key, which can be found in your AppsFlyer dashboard AppsFlyer Android SDK documentation. After initialization, the SDK automatically tracks app installs and opens. To track custom in-app events, such as purchases or user registrations, you would use AppsFlyerLib.getInstance().logEvent() with relevant event names and parameters.
