Android Gets the service started in the device and determines whether a service is started

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

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

1. Access to system services according to Activity_service

Activitymanager = (Activitymanager) getsystemservice (Activity_service);

2. Get the service running in the system

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

The instance code is as follows

1) activity_main.xml
