Hi @all,

I have a design problem with my Android components.

My activity is starting a service which is doing the work in the
background. What I want is that the service informs the activity about
state changes. How can I do this?

Normally I would add an observer but the activity has no reference to
the service. Then I was thinking to take AIDL but this is more for
inter-process communication.

How is it possible that the service informs the activity about state
changes? Both are running in the same process. What can you recommend?

Thank you in advance.
