intentservice no empty constructor, but there is a constructor

Question

I have an IntentService within an Activity, and when I try to call the service, it throws this error, which I find strange because if I have the empty constructor declared.<

Answer 1

public class UploadService extends IntentService {

Your Service is an inner class. If you want to keep it inside Activity, change it to static:

public static class UploadService extends IntentService {
