For example in this Picasso android binding, I can successfully use the .dll in Xamarin.Android, but i do not know how to use it in Xamarin Forms.

推荐答案

您不能这样做！

Xamarin.Forms绑定(.dll)和Xamarin.Android绑定(.dll)确实具有相同的扩展名，但它们彼此不兼容.由于您的Xamarin.Forms项目(PCL，.NetStandard或Shared Project)和您的Xamarin.Android(Android Native)项目是不相同的，并且像其他扩展名一样，.dll也针对特定目标受众进行了开发，因此，您创建的Picasso.dll永远无法直接定位Xamarin.Forms.

Xamarin.Forms Bindings (.dll) and Xamarin.Android Bindings (.dll) do have the same extensions but they are not compatible with each other. Because your Xamarin.Forms project (PCL,.NetStandard or Shared Project) and your Xamarin.Android (Android Native) project are not the same and a .dll like any other extension is made for a particular target audience, in this case, the Picasso.dll you make can never target Xamarin.Forms directly.

您可以做的是创建一个自定义渲染器，可以在相应的Android和iOS项目中使用这些本机库.但是制作这些渲染器本身会很痛苦.

What you can do is create a custom renderer that can use these native libraries in respective Android and iOS project. But making those renderer's will be a pain in themselves.
