# Improved Event Callbacks

June 19, 2025

The Android SDK now provides **more detailed event data** so you get better visibility into ad performance.

- **New unified event system** - A single callback handler for all ad lifecycle events including no-fill, ad served, and impression tracked

- **Richer analytics data** - More granular event types make it easier to understand exactly how ads are performing in your app

- **Easier integration** - Cleaner API that plugs into your existing analytics pipeline with less code
