Join the Xamarin Android Performance and App Size Challenge

Jon Douglas

For the past few releases, we’ve been adding new Xamarin.Android features. Features to help improve your application’s build speed, startup speed, and application size. The most recent release of Xamarin.Android in Visual Studio 2019 and Visual Studio for Mac 2019. Which introduced Startup Tracing to the world. Startup Tracing is a build setting that dramatically improves the startup performance of your Android app. Additionally, a startup profile is created for any Xamarin.Android app used during the startup of the app when enabled. However, that’s not all! We’ve recently blogged on various tools we have added support for that you can use today to benefit from: * Optimize Your Xamarin.Android Builds/ * Faster Startup with Startup Tracing on Android/ * Android’s D8 dexer and R8 shrinker

Android Performance and App Size Challenge We believe the features shipped recently are amazing, but we want you to try them out in your apps and let us know.
