Unable to eject Android phone

When I try to eject my Android phone from my Windows 8 laptop (using the "Safely Remove Hardware and Eject Media" icon in the task bar) I get a "Problem Ejecting USB Composite Device" pop-up with the message:

Windows can't stop your 'Android ADB Interface' device because a program is still using it. Close any programs that might be using the device, and then try again later.

I have a number of background and Windows processes running, but no apps, so any idea what could be causing this? One of the background processes is "abd (32 bit)", so should I just end that task? Or would it be better to just unplug the device and not worry about ejecting it first?

Solution

  • Android uses ADB to communicate with physical devices and emulators. To properly disconnect your phone first stop the ADB server and then eject your device.

    CD C:\Users\<user_name>\AppData\Local\Android\android-sdk\platform-tools
adb kill-server

    Then eject your device.
