title: Why physical emmulator doesn't show?
body: <p>I downloaded Android Studio. When I ran the physical Android device, it shows "Unable to connect to ADB. Check the event Log for possible issues.Verify that your local host entry is pointed to 127.0.0.1 or ::1 for IPv4 or IPv6, respectively."</p>
  
  <p>HELP!</p>
  
  <p>I already downloaded the Android API, Google SDK manager and system service. I don't know why I did that.</p>
