As for the broadcast solution, can an Activity receive a broadcast
while it is rotating? Will all the broadcasts sent to it be received?
About the Messenger, is it possible to create a Messenger from a
Service to an Activity? In the Messenger tutorial, it says "it sends a
Message to the service th
Also, if you are writing an app where you have a service that is just being
used by the code in that app (not being accessed by other apps), and not
looking for the startService semantics... you should probably stop and
make sure you really need a service at all. If you are just binding within

Do please be careful about startService. You should only use one or the
other where you want the associated semantics:
- startService means "I want you do go off and do this work independently
of the caller, with the understanding that someone will take care of
stopping the service as soon as it

startService() uses a variation of the command pattern: you
"communicate" with the service via extras on the Intent passed to
startService() as the command.
If I use startService(), can the Activity communicate with the Service
and vice versa?

If I change the MessengerService into an media player service, a user
can control the media player by the ServiceConnection in the Activity
and the media player service can update the UI according to the state
of media player. The downside is that the playback will be stopped
when a user leaves the

It works! The context is so mysterious in Android.
Another question, in the tutorial (http://developer.android.com/guide/
topics/fundamentals/bound-services.html#Messenger), the mService is
not initialized and mBound is false until the mConnection callback is
called. In the sayHello(), it uses "if

In onDestroy(), I checked whether the Activity is finishing and bound.
If so, I unbindService().
if(isFinishing() && serviceBound){
unbindService(serviceConnection);
Log.d("MyMediaPlayerActivity","Activity: unbindService()");
}

I added following two methods in my Activity:
@Override
protected void onSaveInstanceState(Bundle outState) {
outState.putBoolean("serviceBound", serviceBound);
}
@Override
public Object onRetainNonConfigurationInstance() {
return serviceConnection;
}
And in onCreate() of the Activity, I ad
