While creating a new Prism for Xamarin.Forms project with VS2017 I'm getting the following errors:
Could not find android.jar for API Level . This means the Android SDK platform for API Level is not installed. Either install it in the Android SDK Manager (Tools > Open Android SDK Manager...), or change your Xamarin.Android project to target an API version that is installed. (C:\Users\yoav\AppData\Local\Android\sdk\platforms\android-\android.jar missing.) BlankApp3.Android
