ViewModel updating by a non UI thread

[Lorenzo Maiorfi]

Hi.

Is there a smart way to run on UI thread code that updates UI whenever an observable value is updated by a non-UI thread?

At this time the only viable solution seems to be passing to ViewModel constructor a reference to an Activity or to an Handler.

Any ideas?

More or less this is the best way. Moreover, I always pass Activity to
constructor of View Models as you really need it in many many
situations, for example, to start another activity.

The other way to do is using a BroadCast Receiver

You might noticed that there's an experimental (under
gueei.binding.labs) EventAggregator, which is a light weight
implementation for routing events without dependency.

I personally would suggest using that one (over Broadcast receiver),
but still need to pass a Context to the VM.
