Is it safe for me to save resource id as user preference
<p>Currently, I define several theme in my app</p>

<ul>
<li><code>R.style.Theme_MyApp_Light</code></li>
<li><code>R.style.Theme_MyApp_Dark</code></li>
</ul>

<p>User has the option to save his selected theme in preference. </p>

<p>I was wondering, is it safe for me to save these generated Id into preference? Possible in my next app release, <strong>aapt</strong> generates different resource id?</p>
