title: Best way for Service that starts Activity to communicate with it
body: <p>I have a service that listens to a socket. When receiving certain input it is to create an activity. When receiving other input, it is to kill this activity. I have struggled for a while to make the service communicate with the activity through AIDL (<a href="http://developer.android.com/guide/developing/tools/aidl.html" rel="nofollow noreferrer">http://developer.android.com/guide/developing/tools/aidl.html</a>), but this seems to not be effective. I think AIDL is only effective when the process that is to be talked to is a service, not when it is an activity? I would love some directions or suggestions on how to solve my problem.</p>
  
  <p>Cheers,</p>
