What it refers, pls help me in solving this issue

Answer 1

When you are opening the app you are sync connection, but which is not possible for your device. So it is throwing a IOException.

Answer 2

Uninstall previously build apk if any. restart your eclipse and restart you device and try again

Answer 3

Try killing the Android Debug Bridge (adb) by just running the command adb kill-server and then adb start-server on your command prompt.

Also try disbale/enable the USB Debugging option on your device

Note: If you have not added the android-sdk-windows\\platform-tools or android-sdk-windows\\tools directory to the windows path in your system environments then you can not able to run this command directly. Therefore you need to go this path and after that run the above mentioned command.
