Here are @BrandonMinnick's build optimization tips he shared recently on Twitter.
I used Xamarin.Firebase.Database in a shared project in Xamarin.Forms in Visual Studio and it works. At the moment I am only focusing on an iOS version of an App but the setup is similar for Android.
using FIR = Firebase.Analytics
This is the only setup I needed. I attached all my listeners in my shared code and it works. I can't see why it shouldn't work for PCL but also I haven't tried it.

Are you still unable to install?
Android Studio and VIsual Studio for Mac install the Android SDK in different places by default. If you want to try to start over, you can try a full uninstall as outlined in this guide. After uninstalling, try reinstalling again.
this should help I think
I removed Windows temporary Xamarin folder from users/username/AppData/Local/Temp and removed Mac /Users/username/Library/Caches/Xamarin/XMA folder
Now everything works
Use the PropertyChanged delegate you specify in BindableProperty.Create().
public static readonly BindableProperty IsDirtyProperty = BindableProperty.Create( nameof( IsDirty ), typeof( bool ), typeof( DrivesView ), false, BindingMode.TwoWay, propertyChanged: OnIsDirtyChanged );
private static void OnIsDirtyChanged(BindableObject bindable, object oldValue, object newValue)
