"adb connect" sometimes adds additionally: suffix 4321

When debugging my ADT-1 module, I often connect via the following command

adb connect 192.168.1.x:4321

and this usually works as expected. I noticed that in some cases the connection fails because the command adb connect

adds an additional port suffix to the original address:

unable to connect to 192.168.1.7:4321:4321 // see the extra :4321?

Additional Information:

  • Yes, 4321 is mandatory for ADT-1 devices.
  • Restarting the adb service does nothing useful.
  • Restarting the IDE (IDEA / Studio) doesn't seem to do the trick.

Does anyone know why this is happening? Can this be avoided?

It seems that restarting the tcpip server on the device fixes this. Steps for this:



  • Connect your device to your computer via USB
  • Run "adb usb" to connect to your device via USB
  • Run 'adb tcpip 4321' to restart the tcpip server on port 4321
  • Disconnect the device
  • Run 'adb connect 192.168.1.x: 4321' and it should now connect successfully.

This problem seems to occur when the IP assigned by ADT-1 changes .



adb connect

cannot bind to this address (because it was changed) hence it throws this erroneous error.
