No idea what it means. All i can understand is that it is unable to get the services object during creation. But i am not sure why. I am calling it using startService(new Intent(context, PeriodicUpdationService.class)); where context is getApplicationContext(); In the Manifest file i have declared as <service android:name=".PeriodicUpdationService" android:enabled="true"/> I am totally confused not sure why it is unable to create the service. Please help.
