title: Resolution for android app design
body: <p>I start to design small app for android. But this is my first android app design. And I have a question about devices and displays.
  I have read all developer guidelines at <a href="http://developer.android.com/" rel="nofollow">http://developer.android.com/</a>, all about DPI and pixels. And still not clear with question.
  I want to design in Photoshop CS6 because is the best way for me.</p>
  
  <p>In guidelines i read <strong><em>"One approach is to work in the base standard (normal size and MDPI) and scale it up or down for the other buckets. Another approach is to start with the device with the largest screen size, and then scale down and figure out the UI compromises you'll need to make on smaller screens."</em></strong></p>
  
  <p>I want to start with the largest screen size so this is XHDPI 320DPI. As an example I want to choose Nexus 4. What resolution (pixels and DPI) do I need to choose for PSD? </p>
  
  <p>I think I need to create PSD with 1280x768px and 320dpi. Is that right? If so, when I need to scale down to 160dpi I have to create new PSD with 160dpi and resize the elements from 320dpi?</p>
  
  <p>Please help me someone I'm confused.</p>
