title: Adding files (*.xls) to android project
body: <p>What folder should I put in excel files (*.xls) to android project? I want them to be in the apk files, and how to open them later? I tried to put them in assets folder, and open like that:</p>
  
  <pre><code>    try {
          in = getAssets().open("schedule.xml");
      } catch (IOException e) {
          e.printStackTrace();
          return "can't open the file";
      }
  </code></pre>
  
  <p>but it didn't work.</p>
