title: What dp resolution do I work with for a universal android app?
body: <p>I have been developing an android app and currently optimizing the UI for the majority of phones.
  I am having a lot of difficulty understanding dp resolution. </p>
  
  <p>What is the resolution in DP I am aiming to design my layouts to? I know android has 4 sizes:</p>
  
  <p>xlarge screens are at least 960dp x 720dp
  large screens are at least 640dp x 480dp
  normal screens are at least 470dp x 320dp
  small screens are at least 426dp x 320dp</p>
  
  <p>but that says at least.
  If I am given a phone with 400dp by 800dp and my image views are designed for 640dp by 480dp does android scale it down? If it doesn't then my content looks bad.</p>
  
  <p>Please keep in mind that I don't want to use wrap content to scale my image views because I am pulling my images from a server and I don't know the exact resolution, so the image views will end up all mis-shapen if I use wrap content.</p>
  
  <p>Thank you.</p>
