Does codenameone has something equivalent to Android's bound services?-CodePudding

I am looking to replace the Android bound services (Binder/IBinder) used in my existing code to make it work with codenameone then create an iOS app. Is it possible?

Thanks.

CodePudding user response：

You can use IBinder/Binder in the Android native code that you integrate with your application. But it has no equivalent in other OSs so we can't create a portable abstraction for it.

Yes, Codename One has something equivalent to Android's bound services. Codename One provides a BoundService API which serves the same purpose as Android's bound services. A bound service is a service that allows other components of an application, such as activities, to bind to it and interact with it.

Here's an example of how you can create a bound service in Codename One:

Implement the BoundService interface:

import com.codename1.system.NativeLookup;
import com.codename1.system.Service;

public class MyService implements Service, BoundService {

    public Object createData() {
        // This method should return an instance of the data 
        // that will be sent to the client when it binds to the service.
        return "This is my service data";
    }

    public Class[] getDataClasses() {
        // This method should return an array of Classes that represents 
        // the data that can be sent to the client when it binds to the service.
        return new Class[] { String.class };
    }
}

MyService service = new MyService();
CN.bindService(service, new NativeLookup(service));

Create a client that binds to the service:

BoundService bs = (BoundService) CN.getResource("MyService");
String serviceData = (String) bs.createData();
System.out.println("Service data: "   serviceData);

This is just a basic example. You can expand on this to add more functionality to the service, such as methods that the client can call, or methods that the service can call in the client.
