We often do this by getting the services that the system has started to infer if the server needs to be restarted.

This article describes the services that are started in the Android device and infers that a service is started

1. Access to system services based on Activity_service

Activitymanager = (Activitymanager) getsystemservice (Activity_service);

2. Get the service being executed on the system

Runninglist = activitymanager.getrunningservices (30);//Represents the number of services we want to return 30
