When I try to start my emulator I receive the following:

20:09   adb server version (32) doesn't match this client (39); killing...

20:09   could not read ok from ADB Server

20:09   * failed to start daemon

20:09   error: cannot connect to daemon

20:09   'C:\Users\10349\AppData\Local\Android\Sdk\platform-tools\adb.exe start-server' failed -- run manually if necessary

What was the problem? and how may I solve this problem?

  • What is the code you are using to open the emulator? Jun 4, 2018 at 13:16
  • I open it straight from android studio, this little green icon on the top right

  • Perhaps it's referring to Appium server? If you have the desktop version, launch it manually, then try to launch your emulator. Jun 4, 2018 at 14:06
  • I have try to follow the path to open it manually, but its being terminated once I launch it

  • Did you install it using NodeJS? npm install -g appium Jun 4, 2018 at 14:43

You need to update your android SDK installed within android studio to match the client device version.
