Android : Android wear app not listening to the datachanged() method for dataapi

I have a mobile app for populating the dataapi and implemented a listener using WearableListenerService on the android wear side for listening to the data changes.Previously i was using Android studio and everything was working fine but when i changed to eclipse, wear app stopped responding to the data changes from the handheld side.I am using timestamps with every data packet.I have checked and the mobile app is successfully sending data to the wear but the Datachanged method is not getting invoked.Please suggest any resolutions.
