Java.Lang.NoSuchMethodError

Java.Lang.NoSuchMethodError: no static method "Landroid/text/Html;.fromHtml(Ljava/lang/String;I)Landroid/text/Spanned;"

I'm getting this error on Android 6 and older. On Android 7 it works.
This is happening on a Label Renderer for Android, running this command:

Html.FromHtml(myText, FromHtmlOptions.ModeCompact)

I'm using the Xamarin.Forms version 2.3.3.180, Xamarin.Android 7.0.2.42 and Xamarin 4.2.2.11

Any ideas?
