title: Bitmap size much greater than file size from which it's loaded
body: <p>I'm using the following code to retrieve an bitmap from image file in android:</p>
  
  <pre><code>BitmapFactory.Options options = new BitmapFactory.Options();
  options.inPreferredConfig = Bitmap.Config.ARGB_8888;
  Bitmap bitmap = BitmapFactory.decodeFile(path, options);
  </code></pre>
  
  <p>However, the size of the bitmap is more than double the size of file. Eg, for a file of size 520kb, the bitmap size is around 1.3MB. Is there a way I can get the bitmap of the same size as that of file?</p>
