title: How to set a dynamic background in Android (just like Tumblr Login UI)
body: <p>I am new to Android and I having troubles setting a dynamic background just like Tumblr login UI,</p>
  
  <p>The link below is where I got some help.
  <a href="https://stackoverflow.com/questions/15842901/set-animated-gif-as-background-android">Set Animated .GIF As Background Android</a></p>
  
  <p>But it only works when I load small-size animation, or I have to drop lots of frames of a GIF animation which leads to incoherence. 
  If I load all the frames which will cause OutOfMemoryError, I don't think it's the right way.</p>
  
  <p>Is tumblr uses GIF animation or it's actually a short video? </p>
