Did back key destroy an activity?
<p>I have an activity defined as below:</p>

<pre><code>    &lt;activity android:name="com.example.ui.HomeActivity"
        android:alwaysRetainTaskState="true"/&gt;
</code></pre>

<p>A strange thing is that, when running on emulator, and the back key is pressed, the activity was destroyed (I saw onDestroy() called in log). But when running on my Nexus One phone, and the back key is pressed, the activity is not destroyed (I didn't see onDestroy() called in log).</p>

<p>Could someone tell me why?</p>

<p>Thanks.</p>
