title: How to tell screen resolution in "DP"?
body: <p>I am working on an application based on Galaxy S at the moment. I know that Galaxy S is 480 px wide and 800 px tall, but how much is that in DP?</p>
  
  <p>Lets say if I want to have two Layout side by side, I'll have them setting to 240 px. But how do I know what value I should use in DP unit?</p>
