Why the acitvity will show this weird behavior?
<p>Some times, The DialtactsActivity's launching will show this strange behavior:</p>

<pre><code>onCreate
   ||
onResume
   ||
onDestroy
   ||
onCreate
</code></pre>

<p>.......</p>

<p>Anyone know this scenario? Give me some hint? Maybe some abnormal thing happened?
Thanks very much!</p>
