title: Unable to open debugger port : java.net.ConnectException "Connection refused"

    <p>Error running [app]: Unable to open debugger port : java.net.ConnectException "Connection refused" </p>
  </blockquote>
  
  <p>When I run the DDMS, it shows the connected devices and the process. The trouble occurs just when trying to debug in Android Studio.</p>
  
  <p>In other forums, I've found that something could have changed the port of the debugger, but that doesn't solve my issue.</p>
