title: Android: getAssets().openFd() and FileNotFoundException
body: <p>I am trying to read a txt file from assets folder like that:</p>
  
  <pre><code>descriptor = context.getAssets().openFd("openAccess.txt");
  reader = new FileReader(descriptor.getFileDescriptor());
  </code></pre>
  
  <p>but I am getting this exception:</p>
  
  <blockquote>
    <p>java.io.FileNotFoundException: This file can not be opened as a file
    descriptor; it is probably compressed</p>
  </blockquote>
  
  <p>I don't know what is the problem?</p>
