Question

So, the background service works for me. Now, if the user shuts down, the service will still work, right? Now, when the user restarts the application, I want to access the background service and call some methods. How can I access an instance of a background service?

Thanks guys!

Answer 1

It worked out of the box for me! However, do not use it if you have alternatives, because public static members are not good unless they are final. You can create a static variable with a public scope in the service.

public static BackgroundService bs; @Override public void onCreate(){ bs=this;} 

Then initialize the variable with 'this', which makes it a reference to the current current service. Use it as a link in your activities at any time.

Answer 2

If the service continues to work after exiting your activity, it depends on how you start it. (Read about this in the startService () / bindService () documentation) If your Service is still running, startService () / bindService () calls will connect you to your "old" service.

Answer 3

If you want to communicate with the background service. You cannot use the binding mechanism, and about this you can access this network: android evolve

there is an example to learn how to use the background service

Many thanks
