Do not start the activity, you can start the service

 
Intent intent2 = new Intent (context, xxxService.class); 
context.startService (intent2);

Thank you, illustrated hjue, now there is a problem is that my activities there is a logical interface, ah, If you start service, then there is no logical interface to perform activities of how to do? Click on the icon to run because the normal case, starting from the active interface, activity in the logic interface can be implemented. Now how do?
