TLDR: The Xamarin Android Device Manager does not seem to work well with VS2015.

First, I disabled Hyper-V (necessary for Visual Studio Android Emulator). Then I tried to open Android Studio and use the built in SDK manager. Here I upgraded to Android SDK Tools 26.1.1.

It downloaded some other tools too:

Afterwards, I startetd Xamarin Android Device Manager in Visual Studio. From there I pressed the Start button for one emulator, but it never started up. Then I tried to open the SDK Manager, but it never openened (even after a restart it didn't open). Since that didn't worked I tried to open the Xamarin Android SDK Manager directly in VS. Here I got the message that I have to upgrade and there was a link to this page. Here I found the following information:

Overview

The Xamarin Android SDK Manager helps you download the latest Android components that you need for developing your Xamarin.Android app. It replaces Googles standalone SDK Manager (which was deprecated in version 25.2.3 of the Android SDK Tools package).

If you are using an earlier version of the Android SDK that still supports the Google Android SDK Manager, you can install the Xamarin Android SDK Manager without creating a conflict Visual Studio will use the Xamarin Android SDK Manager instead.

Older VS Versions

For VS2015 and older, we recommend downgrading SDK Tools to 25 and using the old Google Emulator manager GUI. SDK tools 25 can still be used alongside API 26, 27, and newer, and won't impact development for new platforms. This will give you an interface for managing your Android SDK for older versions of VS.

If I get this right it generally won't work with VS 2015, because you need the new tools, but my setup only works with the old tools. Therefore I downgroaded to my old Android SDK Tools. Now the SDK Manager opens up again.

I even can't use Google Emulator Manager, because

If you are targeting Android 8.0 Oreo, you must use the Xamarin Android Device Manager to create and configure virtual devices.

Now what? How can I have an emulator with Android 8? The Visual Studio Emulator for Android is no longer supported, the Xamarin Device Manager does not work well with VS 2015, and the Google Emulator Manager doesn't support Android 8 (Oreo).
