Implementing Mixpanel on Android (Kotlin)

Android apps need the same disciplined analytics layer as iOS: a singleton or injected `AnalyticsTracker` that wraps Mixpanel’s Android SDK, initialized in `Application.onCreate` with your token and opt-out flags respected for GDPR and Play policy.

Add the Mixpanel Android dependency via Gradle, keep the SDK version aligned with iOS when possible, and document ProGuard/R8 keep rules so event classes and the SDK are not stripped in release builds—otherwise you silently lose data in production.

Emit events from ViewModels, use cases, or composable callbacks—not from every recomposition. For Jetpack Compose, track user actions and meaningful screen impressions once per navigation entry; debounce rapid taps that should count as one conversion.

Mirror your iOS event catalog: same event names, same property keys, same identity rules. Use `identify` after authentication, set people properties for plan and experiments, and call `reset` on sign-out. Super properties for OS version, device class, and app flavor help segment crashes versus behavior issues.

Integrate subscription analytics by listening to Google Play Billing or RevenueCat callbacks and mapping them to the same revenue events you use on iOS (`subscription_started`, `trial_converted`, etc.). Funnels in Mixpanel only help when both platforms spell events identically.

I regularly implement Mixpanel on Kotlin apps alongside Swift clients so founders get one dashboard for the whole product. If your Android build is missing analytics or out of sync with iOS, a focused integration sprint fixes tracking and gives your team trustworthy funnels.
