我正在尝试构建My Xamarin.Adroid项目以进行发布.但是我一直收到这个错误.网络上的普遍共识是我的Targeting框架和最低SDK版本必须如此，但是我尝试了所有这些都无济于事.

这两个SDK都安装在我的计算机上，我还添加了Xamarin表单的最新预览.

我尝试的一切似乎都没有效果.关于此的任何帮助将不胜感激.

谢谢.

类似于方法Android.Widget.TextView::SetTextAppearance(System.Int32)首次出现在API23中:M.您需要更改编译和/或目标版本以指向M./p>

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.
