What is the usage of startService in Android?

The startService() method in Android is used to launch a service. A service started using this method will continue to run in the background until it is stopped either by calling the stopService() method or by the service itself calling stopSelf().

Here is how the startService() method is used:

Intent serviceIntent = new Intent(context, MyService.class);
startService(serviceIntent);

In this case, MyService.class is the class name of the service to be started, and context is the context object. After calling the startService() method, the system will invoke the onCreate() method and onStartCommand() method of the service, thus starting the service and executing the corresponding operations.
