If Eclipse fails to recognize your running Android emulator (no visible emulator in the DDMS view for example), you might see an error message in the console window like this:
[2012-12-19 07:53:37 – adb] ADB server didn’t ACK
[2012-12-19 07:53:37 – adb] failed to start daemon
And you get an Adb Error dialog, saying:
Adb failed to restart!
Make sure the plugin is properly configured
Like pictured below:
You can solve this problem with the following steps:
- Open the windows task manager (Ctrl + shift+ escape)
- End/kill all adb.exe processes
- In Eclipse, while the Android emulator is running, go to DDMS -> Devices
Click the down-arrow to see the menu, and click “reset adb” like pictured below
- Your emulator should now appear in the devices window again.
If this should not work, try restarting Eclipse and the emulator, and try the steps again.
