I am trying to build My Xamarin.Adroid project for release. But i keep getting this error. General consensus on the web is that that my Targeting framework and minimum SDK versions have to be so and so, but I have tried them all to no avail.
Both those SDK's are installed on my machine, I also have the latest preview of Xamarin forms added.
Nothing I am trying seems to work. Any help regarding this would be greatly appreciated.
Thank you in advance.

Looks like the method Android.Widget.TextView::SetTextAppearance(System.Int32) first appeared in API23: M. You'll need to change your compile and/or target versions to point to M.
