i am using my samsung galaxy3 device for testing my apps from last two months. It is working fine. But suddenly from this morning when i connected my device to my system it is not showing up in the "Android Device chooser" window. I have checked, USB debug mode is in checked state only in my device.

Can anybody guess the problem. It is little urgent.

Thanks, Nehatha

Use a shell of some sort (Run -> cmd) and browse to the /platform-tools/ directory inside the place you installed the Android SDK Tools.

Shut down Eclipse, unplug your device and try running:

adb kill-server
adb start-server

Plug it back in and run 

adb devices

If you can see it, good. Now run:

adb logcat -c
adb logcat

This will flush the current logcat output and then show the logcat output in the shell as it updates (do something on the device and the log will update). Stop it with Ctrl-C and restart Eclipse.

This has helped for me sometimes.

Also, rebooting helps.

I have another similar issue over here which I haven't found an answer to yet: Device going offline randomly (and appearing multiple times as offline) in Eclipse - fixes?

Hope some of it helps.

  • Maybe try to reinstall your USB drivers? Remove them and install 'em again from the Google USB Driver list. Not much else to do... :/ – Codemonkey Mar 03 '11 at 11:19
  • Hi Klaus, it is working after factory reset.. anyway thank for your suggestions. – Venkat Papana Mar 08 '11 at 15:01
  • You mention USB drivers. The google USB driver list refers to several OEM's... What if mine isn't listed? – baash05 Oct 18 '11 at 11:06
  • this response has saved me twice now in the past few days so thanks for that. Any idea what is happening to require this fix? – DannyT Nov 02 '11 at 19:39

I have the same problem and I figured out the solution for me.

  1. On the home screen of your device choose Menu > Settings > Applications > Development.
  2. Make sure that ‘USB debugging’ is checked.

Hope it will help someone :)

I had similar issue, what worked for me was switching to "connected as camera" mode instead of "connected as media device" from the USB options menu, then performing Klaus's solution (kill server, start server).

Finally my device is working after "Factory data Reset".

Thanks you all for your suggestions, even those suggestions not worked for me, I came to know about other useful.

Thank You.
