Xamarin: ADB Binary is Obsolete

Question

When I run (or first run) a Cross-Platform Android app in Visual Studio, I a message that the ADB Binary is obsolete and should be updated. Not sure from where.

Here are my installed tools:

I created a few starter apps and they work. Just not sure how to address this issue.

Also, when starting the app in VS I get this output:

For anyone who was getting this error but the accepted answer was not working here is an alternative solution. For me I already had the latest SDK installed but was still getting this message. To fix it I used the SDK Manager to uninstall the Android SDK Platform-tools.

After you do this Visual Studio will immediately tell you that the SDK is not in a valid state and it will re-install the entire SDK. After it is finished you need to rebuild your project in order to launch your app.
