                                          {
                                            if (string.IsNullOrEmpty(FirstName)) 
                                            {
                                              await Mvx.Resolve<IUserInteraction>().AlertAsync("First Name is Required");
                                              return;
                                            }
                                            //do work
                                          });
        }
}

Alert callback

public ICommand SubmitCommand
{
        get
        {
            return new MvxCommand(() =>
                                          {
                                            if (string.IsNullOrEmpty(FirstName)) 
                                            {
                                              Mvx.Resolve<IUserInteraction>().Alert("First Name is Required");
                                              return;
                                            }
                                            //do work

                                            if (await Mvx.Resolve<IUserInteraction>().ConfirmAsync("Are you sure?"))
                                            {
                                                //do work

Adding to your project

1. Follow stuarts directions (step 3) - http://slodge.blogspot.com/2012/10/build-new-plugin-for-mvvmcrosss.html
2. Grab the UserInteractionPluginBootstrap file from appropriate Droid/Touch folder. Drop into your project in the Bootstrap folder, change the namespace.

I will be working on a nuget package as time permits.
