title: Failed to get the required ADT version number from the
body: <p>Yesterday I tried to install ADT plugin to Eclipse, but when I restarted it I found the next screen:</p>
  
  <p><a href="https://i.stack.imgur.com/ThKKp.png" rel="noreferrer"><img src="https://i.stack.imgur.com/ThKKp.png" alt="Error"></a></p>
  
  <p>When I click on "Open SDK Manager", I see something loading but after waiting it doesn't open anything:</p>
  
  <p><a href="https://i.stack.imgur.com/9m5GA.png" rel="noreferrer"><img src="https://i.stack.imgur.com/9m5GA.png" alt="Loading"></a></p>
  
  <p>After that this dialogue closes and I don't see anything else of Android</p>
  
  <p>PS: Ignore the code behind.</p>
