Android activity lifecycle when clicking on the HOME button
<p>I have an application with only one activity running in the Android emulator:</p>

<ul>
<li>When this activity has the focus and when I click on the HOME button, the onPause() and onStop() callbacks are invoked.</li>
<li>From there, if I run the "ps" command from an ADB shell, I can see one process corresponding to my application.</li>
<li>Now, if I start the application again, the onCreate(), onStart() and onResume() callbacks are invoked.</li>
</ul>

<p>Since onCreate() is invoked, this seems to imply that the activity was either killed or shutdown. But in that case... why can I see it by running the "ps" command ?</p>
