title: How can I access files in res/raw folder or any other location in android?
body: <p>I posted a day ago similar question, but I simplified my problem here so hoping to get resolved. 
  I think I know when reading a file with 'filename.ext', I use</p>
  
  <pre><code>InputStream inputStream = getResources().openRawResource(R.raw.filename);
  </code></pre>
  
  <p>But how I can access multiple files? I need a function looks like</p>
  
  <pre><code>InputStream inputStream[] = getResources().openRawResource(R.raw.*.*);
  </code></pre>
  
  <p>Thanks!</p>
