title: Where to store images in Android drawables folder?
body: <p>I am working on Android application that should support 2.1 till latest Android OS (4.2) version. Currently I have few images to display in my image-gallery module.
  I need to support my app on all devices (smartphone and tablet) which support OS ranging from 2.1 to 4.2 (latest).</p>
  
  <p>Each image is roughly of size 368X387, 50 KB each, PNG type</p>
  
  <p>My workspace res  contains following drawable folders:</p>
  
  <pre><code>drawable-hdpi
  drawable-ldpi
  drawable-mdpi
  drawable-xdpi
  </code></pre>
  
  <p><em>I have some confusion around</em> </p>
  
  <ol>
  <li><p><strong>In which folder should I store the images, and how will that matter?</strong> </p></li>
  <li><p><strong>Do I need to have different resolution based images for different type of devices?</strong></p></li>
  </ol>
  
  <p>Thanks.</p>
