As shown in my last post, a MvxViewModelRequest contains a dictionary named PresentationValues that can be very useful in passing around data that your presenter might find useful. Let's say you that in your view model you know that when you request to show a view model you know that you want to clear the app's back stack before showing it, such as after a login operation so that the login screen is no longer in…

As part of our effort to automate taking screenshots, we also need the ability to spin up Android emulators via the command line. This all needs to run headless, so it's necessary to be able to spin up Android emulators from the command line.
