"Prism.Unity 6.3.0 is not compatible with monoandroid81"

Question

I am trying to add Prism to my Xamarin Forms app. Following this video by Brian Lagunas, I am attempting to add Prism.Unity to all of my projects (.NET Standard, Droid, iOS, and UWP). However, I am getting these errors. Does the latest version of Prism.Unity not support the latest versions for Android and iOS?

First of all the latest version of Prism for Xamarin Forms is 7.0 and there is a 7.1 preview. Prism 7 was updated for netstandard support and has a large number of changes that make developing apps a lot easier. Here are some blog articles to help you with Prism 7

• Prism 7.0 - preview 3
• Upgrading to Prism 7.0
• Prism 7.1 - preview 1

Second you're installing the wrong package. You need to install one of the following:

• Prism.Autofac.Forms
• Prism.DryIoc.Forms
• Prism.Unity.Forms
