emulator not showing in adb devices

Question

if i start an emulator using the android SDK r12 it does not show up in the adb devices list

win7 64 // android 2.2 (not an actual hardware device - just the emulator)

what could be the problem?

Answer 1

You can also try to :

 adb kill-server
 adb start-server

to restart the adb server . Maybe something went wrong with the adb-server . This happens a lot, and many such issues can be solved by restarting the server.

Answer 2

Make sure that you are at the path and give command.

android-sdk_r12-windows\android-sdk-windows\platform-tools>adb devices

I am also using win7 64 It is working for me. If you are getting any error. Mention it.

Also make sure that USB debugging is enabled in your device.

 Settings>Applications>Development>USB debugging

Can you able to see device in eclipse? If not then close your emulator and open it again.

有时甚至 adb 本身也会出错，对我来说总是很好用的旧 pkill：

pkill -9 adb
