Hello,
You could find the following content from this documentation: Change a .NET MAUI app icon.
Adaptive launcher icons are composed icons, using a background layer and a foreground layer, and an optional scaling value. For more information, see the Composed icon section. If the composed icon is defined, by specifying the ForegroundFile attribute, an adaptive launcher icon will be generated. The following XML demonstrates defining an icon that is used as an adaptive launcher icon:
<ItemGroup>
<MauiIcon Include="Resources\AppIcon\appicon.svg" ForegroundFile="Resources\AppIcon\appiconfg.svg" ForegroundScale="0.65" Color="#512BD4" />
</ItemGroup>
Therefore, you could use the <MauiIcon Include="Resources\AppIcon\appicon.svg" ForegroundScale="0.4" Color="#fff" />
for Android platform to set the same effect as Xamarin.Android.
Best Regards,
Alec Liu.
