title: Android app optimization regarding images
body: <p>The application I am working on will have a lot of images (listviews where every list item have an image, gridviews with images, gallery of images), so at the end of the development in the drawable folder will be about 1000 or more images. Right now I have about 200 images in drawable folder.</p>
  
  <p>Is it right to put all the images in the drawable folder or which is the optimal way to add them ?</p>
  
  <p>Images are used for:</p>
  
  <ul>
  <li><p>Gridview</p></li>
  <li><p>ListView for each Gridview Item</p></li>
  <li>Gallery for each listView item</li>
  </ul>
