Do Messages block in Android
<p>Im writing an app which loads data from a rest interface.
for this task i use a service which gets called by the activitys. Those calls are based on the "Message". I do it like that because i thought that just sending a message does not result in a blocking of the UI thread (i used much of the RemoteService example code from the android docs). But it feels like if the UI thread ater sending a message still gets blocked (ui doesnt update until the programflow, caused by the message has stoped).</p>

<p>Am i getting something wrong about the whole idea of the message system ? do i need to start the service in a separate thread to get around this ?!</p>
