title: How to get URI from an asset File?
body: <p>I have been trying to get the URI path for an asset file. </p>
  
  <pre><code>uri = Uri.fromFile(new File("//assets/mydemo.txt"));
  </code></pre>
  
  <p>When I check if the file exists I see that file doesn't exist</p>
  
  <pre><code>File f = new File(filepath);
  if (f.exists() == true) {
      Log.e(TAG, "Valid :" + filepath);
  } else {
      Log.e(TAG, "InValid :" + filepath);
  }
  </code></pre>
  
  <p>Can some one tell me how I can mention the absolute path for a file existing in the asset folder</p>
