Avalonia Mobile (Android & iOS)

App-level concerns only. Packaging, signing, APK/IPA publishing: see avalonia-deployment. Version labels: see avalonia-versions.

Requirements

Standard solution layout (from avalonia-dotnet-templates xplat template): shared App project + *.Android head + *.iOS head (+ Desktop/Browser). Template defaults: Android SupportedOSPlatformVersion 23, iOS 13.0, AndroidX SplashScreen package referenced.

Android startup

(12.0+) Application class + activity

// Application.cs — initialization moved here from the activity
[Application]
public class AndroidApp : AvaloniaAndroidApplication<App>
{
    public AndroidApp(IntPtr javaReference, JniHandleOwnership transfer)
        : base(javaReference, transfer) { }

    protected override AppBuilder CustomizeAppBuilder(AppBuilder builder)
        => base.CustomizeAppBuilder(builder).WithInterFont();
}

// MainActivity.cs — non-generic
[Activity(
    Label = "MyApp",
    Theme = "@style/MyTheme.NoActionBar",
    Icon = "@drawable/icon",
    MainLauncher = true,
    ConfigurationChanges = ConfigChanges.Orientation | ConfigChanges.ScreenSize | ConfigChanges.UiMode)]
public class MainActivity : AvaloniaMainActivity { }

CreateAppBuilder() / CustomizeAppBuilder() were removed from AvaloniaMainActivity — put builder customization in the AvaloniaAndroidApplication<TApp> subclass or App. (The IntPtr, JniHandleOwnership constructor is the standard .NET-Android requirement for Application subclasses; the template may omit/inline it — copy from the generated head.)

Type chain: AppCompatActivity -> AvaloniaActivity -> AvaloniaMainActivity.
