body: <p>I have this error on my Android project:</p>
  
  <blockquote>
    <p>[2015-11-24 20:50:09 - Dex Loader] Unable to execute dex: method ID not in [0, 0xffff]: 65536

  <p>I read that, I should enable multidex but I can't. </p>
  
  <p>I have this problem when I added <strong><em>poi-3.13-20150929.jar</em></strong> and <strong><em>poi-ooxml-3.13-20150929.jar</em></strong> in libs folder of my project. I added this library becouse I must write an xlsx file.</p>
  
  <p>So, I would like to add multidex to resolve problem, but I don't say the way.</p>
  
  <p>Please help me! Thanks!</p>
