title: ADB not responding. You can wait more,or kill "adb.exe" process manually and click 'Restart'
body: <p>I have installed Android Studio.
  Then I have updated the Android SDK.
  Now when I start Android Studio, this message pops up:</p>
  
  <blockquote>
    <p>ADB not responding. You can wait more,or kill "adb.exe" process manually and click 'Restart'</p>
  </blockquote>
  
  <p>The dialog has 3 options: Wait more, Restart and Cancel. 
  But all of them 
  gives me the same result, i.e. a message <strong>Waiting for ADB</strong> appears and I can't do anything with Android Studio. </p>
  
  <p>I have to kill the program using windows task manager! I'm using windows 7.</p>
  
  <p>Can anyone help me on this?</p>
