Join the Xamarin Android Performance and App Size Challenge


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.
