public interface MyListener {
public void success();
public void failure();
}
>From your activity:
myServerConnectionHandlerObject.getImages(new MyListener() {
//implement both methods here.
});
public class MyServerConnectionHandler {
public void getImages(MyListener l) {
//do net stuff on success call l.success(), on failure l.failure()
}
}
This is very basic, you need to expand and handle various scenarios
