title: Layout looks different on devices
body: <p>Hi My app looks different on different devices. I use Samsung Galagy S2 as my testing device, but when I tried install app to another device Samsung Galaxy Note 3.</p>
  
  <p>Display resolution: 
  Samsung galaxy S2: 800x480(hdp)
  Samsung galaxz Note 3: 1920x1080(xxhdp)</p>
  
  <p>My app looks on:
  Samsung galaxy S2 like <a href="http://www.fastimages.eu/images/hdp.png" rel="nofollow">THIS</a>
  Samsung galaxy Note 3 like <a href="http://www.fastimages.eu/images/xhdp.png" rel="nofollow">THIS</a></p>
  
  <p>As you can see in first picture it looks good but on Note 3 there are a lot of empty space at bottom of app. All images I use are xxhdp and hdp too. The problem is in gap between buttons. I set it in dp so I thought in every device it will look like in my phone. But on galaxy S2 and galaxy Note 3 it looks same gap.</p>
  
  <p>This is my layout.</p>
