title: How can I update my ADT in Eclipse?
body: <p>I have tried to update my Eclipse. Currently I have till 2.2 Android SDK in my Eclipse. Yesterday I have updated my Eclipse like this:</p>
  
  <p>Eclipse -> window -> Android SDK Manager -> I have checked two check-boxes from list. Tools -> Android SDK Tools and Android SDK Platform Tools.</p>
  
  <p>I have posted here some last lines of the message which I get from downloading and installing: </p>

  <p>In preferences I received this error:</p>
