Enjoy **much** faster PNG loading on Android now, as the _libpng_ library is automatically packaged with your applications. Various measurements, like [this one](https://github.com/castle-engine/castle-engine/issues/327), or [testing “The Unholy Society” UI loading time](https://unholy-society.com/) confirm that the speedup is huge, even more than 10x compared to previous `FpImage` that we used on Android.

In general, there’s no need to do anything for developers. The [Android service “png”](https://github.com/castle-engine/castle-engine/blob/master/tools/build-tool/data/android/integrated-services/png/README.md) will be automatically added to the projects that include some PNG files in their [data](https://castle-engine.io/manual_data_directory.php). But you can also request PNG explicitly (just for Android, or for all applicable platforms), follow the [docs](https://github.com/castle-engine/castle-engine/blob/master/tools/build-tool/data/android/integrated-services/png/README.md).

And you can enjoy a new faster level loading in our [new platformer release on itch.io, that includes an Android (APK) build](https://castle-engine.itch.io/platformer).
