Xamarin android app restarting on orientation change with newer android versions

Question

Hi,

Our Xamarin android app is restarting whenever the device orientation is changed. We have configured the main activity with the following:

[Activity(Theme = "@style/MainTheme", MainLauncher = true, ConfigurationChanges = ConfigChanges.ScreenSize | ConfigChanges.Orientation)]

This seems to work with older Android versions such us Andorid 9 but with Android 12/13 devices the app restarts on orientation changes.

Any ideas why this is not working on newer Android versions?

Hello,

You can try to add ConfigurationChanges = ConfigChanges.ScreenSize | ConfigChanges.Orientation | ConfigChanges.UiMode | ConfigChanges.ScreenLayout | ConfigChanges.SmallestScreenSize to your [Activity] attribute.

Best Regards,
