How can we restart the service?

Question

I am developing an Android application that has a background launch of a service.

When I replace the application from the "Recent Application List", this will disable the application and terminate the service. (The following method has code for the same.)

    @Override
public void onTaskRemoved(Intent rootIntent)
{
       //code to be executed
       //Stop service
       super.onTaskRemoved(rootIntent);
    }

The service start code is in the Application class (onCreate ()), it will never be executed if the application resumes.

Positive scenario

1) If I restarted the application after the service was successfully completed, a new instance of the application will be and the service will also start.

Negative scenario
