How to tell if a service is running:

/*** How to determine if a service is running * *@paramMcontext *@paramServiceName is the class name of the package name + service *@returntrue to indicate that the service is not running, false*/     Public Static Booleanisservicework (Context mcontext, String serviceName) {BooleanIswork =false; Activitymanager Myam=(Activitymanager) mcontext. Getsystemservice (Context.activity_service); List<RunningServiceInfo> myList = myam.getrunningservices (40); if(Mylist.size () <= 0) {            return false; }         for(inti = 0; I < mylist.size (); i++) {String mname=Mylist.get (i). Service.getclassname (). toString (); if(Mname.equals (serviceName)) {iswork=true;  Break; }        }        returniswork; }

A possible usage scenario is to force a specified service to stop.
