I got the above error message in Android ADT Console while trying to debug an Android Project, though the App got installed on the device properly and worked fine normally, but IOException: Unable to open sync connection! message while trying to debug.

1. Unplug the USB cord connection.
2. Restart IntelliJ Android Studio IDE.
3. Kill adb process from Task Manager/Activity Monitor.
4. Run Eclipse.
5. Reconnect your device and try again.

• Ensure that your device is properly recognized by your computer.
• Check for any updates for your Android SDK and tools.
• Make sure that your device's battery is charged sufficiently.
• Try using a different USB cable if the issue persists.
• Verify that your device is not in a low-power mode that might affect debugging.
• Look for any other applications that might be using adb and close them.

If the above steps don't solve your problem, check the "USB Debugging" Developer option on your device by going to Settings ( Settings -> Applications -> Development -> USB debugging). Just Uncheck the option and re-check it. You may also try changing the USB port, or trying to work with some other USB cord.
