title: android equivalent to PHP's function explode()
body: <p>Pretty much self-explanatory.</p>
  
  <p>I have a string:</p>
  
  <pre><code>8:4,7:2,...
  </code></pre>
  
  <p>I need to get the values from this, the length of the string is not defined, it just has this format:</p>
  
  <pre><code>id:quantity,id:quantity,...
  </code></pre>
