title: Different Text Size under same screen resolution but different dpi in two Android machines
body: <p>I have two Android machines - Samsung Galaxy Tab and HTC Flyer. They both have 1024x600 screen. However Tab has 240dpi screen while Flyer has 160dpi according to the log from <code>Context.getResources().getDisplayMetrics()</code> method.</p>
  
  <p>My problem is that, I have a <code>TextView</code> defined, and according to those Android document, using unit of <code>dp</code> should give same physical size under different <code>screen density(dpi)</code>. But what I observed is that, the text size appeared in Flyer is obviously smaller than that in Tab, no luck in using <code>sp</code> too. I want them to be in same size. Any clue in solving this problem in general?</p>
  
  <p>Thanks in advance.</p>
