We're also unable to use any app icon at all, tested on 2 Android devices (and Emulator) with 2 different machines and installations of VS17.1-17.2 Preview. We used various SVG files for our tests.
Not even the default .NET icon from a fresh .NET MAUI Blazor project template shows up - It's always the default Android icon.

Is this thread dead without resolution?

[blackforest-tom]

We found a possible cause and a workaround:
The problem seems to be that not all necessary PNG files are generated from the SVG.
Placing the Android app icons as PNGs into Android resources (as you would in Android Studio) and linking them directly from the manifest works for now.

@blackforest-tom how to solve issue feom visual studio 2022 ?
Any solution?
Where iş android resources directory in MAUI app?

@cetindogu
Create a "Resources" directory in your Platforms/Android folder, that will be merged to your platform-independent resources for an Android build. You can create the App Icon assets in Android Studio.

I have a similar problem but not the same :

if I move the appicon.svg from /Resources to /Resources/Images
It doesn't compile : I got an arror on mipmap/appicon not found.

IMHO, the folder shouldn't matter as it's a MauiIcon and it should use my path to generate things.

I think this is a duplicate of #5652 and I think half the time when files are moved in VS the IDE decides it does not want to track the files and adds an explicit remove for everything.

You can see things like this in the repo csproj:

	<ItemGroup>
	  <MauiImage Remove="Resources\Images\new256icon.png" />
	</ItemGroup>

Also, if you look at the android manifest you can see that it explicitly sets the icon to be android:icon="@mipmap/appicon": https://github.com/nssidhu/AppIconAndSplashScreenSample/blob/master/AppIconAndSplashScreenSample/Platforms/Android/AndroidManifest.xml#L4

As of GA, the MauiIcon was just to generate the icons in the correct format and then the correct icon would be selected by the developer in the manifest. This was because you can actually have multiple icons in an all and you can change them at runtime.

However, I do believe not setting the icon to at least the first one (and most likely the only one) is a much better experience. If you want a specific one, you can totally go edit the manifest with the correct one and then add the rest as the activity alias.

Improvements are happening here: #7968

Closing this as a result of the duplicate and the issue will be tracked there.
