title: Why Android xml layout file doesn't recognize content assist by ctrl+space?
body: <p>I am facing problem with eclipse that is when I am using the Android xml layout file to design a screen, I try to add attribute to an element that I have already created. I used to type two letters of the attribute then tap ctrl+space so it will show list of all available attribute by IntelliSense. Now it is not showing anything, instead it is showing a message at the bottom of the screen like below image. </p>
  
  <p>Anybody faced the problem and solved it?</p>
  
  <p>Appreciate your help because it is slowing down my work.</p>
