Remove a specific item from a Set in Sharedpreferences
<p>I have a Set of Strings in my sharedPrefs. I would like to remove a specific item in the list</p>

<pre><code>&lt;set name="items"&gt;
&lt;string&gt;217372223&lt;/string&gt;
&lt;string&gt;222015066&lt;/string&gt;
&lt;string&gt;217771052&lt;/string&gt;
&lt;string&gt;220431322&lt;/string&gt;
</code></pre>

<p>So I would like to just remove say, 217372223 but keep the rest?</p>
