Android Studio Debugger Port Error - "handshake failed - connection prematurely closed"

When I try to attach the Android Studio Debugger to a process, I get the following error:

Error running Android Debugger (8603):
Unable to open debugger port (localhost:8603): java.io.IOException "handshake failed - connection prematurally closed"

Kudos to whoever spelled prematurely that way. Anyway, how do I get around this problem?

I'm using Android Studio 1.2.2 on Ubuntu. This did not help.

Previous steps like kill server, restart Android Studio did not work for me at all. Also tried to reinstall tools.

In Run -> Run/Debug Configuration settings -> Debugger try to change Debug type: from Native Only to Java Only

In my case running the following commands from the Terminal window (Android Studio) resolved the issue:

adb root

adb kill-server

adb start-server

If someone encounters the issue:

connection shut down by remote side while waiting for reply to initial handshake

start the emulator in android studio, open the terminal tab of android studio, type adb root, this worked for me to start debugging again. Probably adb kill-server and adb start-server will also work.

What did not work:

  • Invalidate cache and restart
  • Restart PC

In my case, as a last resort, I had to literally factory reset the device.

I tried:

  • restarting the device
  • turning on/off USB debugging
  • restarting Android Studio
  • clearing Android Studio caches
  • cleaning the build
  • restarting adb
  • restarting Android Studio's adb.
  • restarting my laptop
  • etc.

It shows that your previous debbugger was not closed. You should click stop (red button) to stop your attach previously, and rerun your debbugger. It would attach again

In my case, often the reason is bad USB cable. Just replace another, better USB cable will work.

I didn't need to restart my device, only restarting android studio fixed it ( clean your project if needed).

If doesn't work then restart your device.

I had to restart both my android device and android studio. That seemed to work for me.

* daemon not running. starting it now at tcp:5037 *

On Windows, restarting Android Studio didn't work. I instead killed the "adb.exe" process then retried.

Maybe you should consider retaining only one device or a emulator, because Android Studio or Intellij IDEA only accept one device or emulator when debugging. It works well for me. I hope this can help.

The best and one solution for me was just to restart Android Studio.

Before I tried to restart adb server from command prompt or disable and enable adb integration from tools->Android->Check/Unchek the line, unplug and plug device , but nothing helped.
