Getting Messege Twice Using Imvxmessenger

I am working on Xamrin Android Application and I am using MvvmCross.In my application I have used IMvxMessenger.But I am getting messsge twice when I change the view and comeback t

Solution 1:

Views (whether Activities or Fragments) are created and destroyed all the time. Since you are subscribing in OnCreateView(), you should unsubscribe in OnDestroyView().

What's likely happening is that OnCreateView() is being called multiple times and causing multiple subscriptions to be added. MvxMessenger is broadcasting the message to all subscribers. If a View is destroyed, but hasn't unsubscribed, it's likely to crash since the callback no longer exists.
