I also faced this issue. Adb disconnect my Android device each time just after installing the app in android device from eclipse. The issue was with my USB Cable.

We feel your pain. In case you're using the command-line, you can do the same thing by typing "adb kill-server".

Answer 4

Yup, you are right. It seems to be a software issue.I have faced this annoying thing many times, it happens now and then. I think what happens is that the adb's connection with the device/emulator breaks or becomes faulty, so android starts showing the device as offline.

To correct this problem. Go to DDMS-->Devices Tab-->Click the option "Reset adb" (which is the last option, on clicking the dropdown arrow) . You will then see some error report in the console, but after a minute your emulator would be ready to be used without problems. I do it all the time and it works. Try this instead of manually plugging/unplugging the device.

I find it faster to just plug/unplug, but doing the following in command-line should do the same thing:

adb kill-server
adb start-server
