title: Android - Change value in strings.xml
body: <p>So inside strings.xml I have a string called change_bg  and I'd like to change it's value according to click events.</p>
  
  <p>I know that in order to get the value you use  </p>
  
  <pre><code>changeBG=getString(R.string.change_bg);
  </code></pre>
  
  <p>But I don't know how to SET the value of 
  <code>R.string.change_bg</code></p>
  
  <p>Please let me know how.</p>
  
  <p>Thanks in advance!
