title: About Android image and asset sizes
body: <p>I need to clarify some doubt about the image assets  for my app,</p>
  
  <p>if I specify in an xml file that the height of something [image view] is 50 dip height</p>
  
  <p>which type of screen should  i choose from the resources folder?</p>
  
  <pre><code>drawable, hdpi, ldpi, mdpi, xhdpi,
  </code></pre>
  
  <p>to have the 50 px height image,</p>
  
  <p>and what is the percentage for bigger, smaller size images compared to the base image,</p>
  
  <p>like in iOS, @2x, is literally 2 times the size of the image, and you say programatically the normal size,</p>
  
  <p>thanks! </p>
