How to know if contact / phonebook list or database is updated android?

I have implemented a sync adapter which sends all my contacts over the server. But now I am faced with the issue that how the system can respond if it contact list has been updated.

I used the content observer to find out but it seems to be limited to activity lifecycle.

This is my code:

class MyObserver extends ContentObserver {
    public MyObserver(Handler handler) {
        super(handler);
    }

    @Override
    public void onChange(boolean selfChange) {
        this.onChange(selfChange, null);
    }

    @Override
    public void onChange(boolean selfChange, Uri uri) {

        Log.e("change   ", "contact");

    }
}

To register it:

context.getContentResolver().registerContentObserver(
            Contacts.CONTENT_URI, false, new MyObserver(new Handler()));

Isn't there any broadcast to notify about it.

Or I have to make a service for it.

For that you have to run a service as follows

public class ContactService extends Service {

MyObserver observer;
@Override
public void onDestroy() {
    // TODO Auto-generated method stub
    getContentResolver().unregisterContentObserver(observer);
    super.onDestroy();
}

@Override
public void onCreate() {
    System.out.println("service created");
    observer=new MyObserver(new Handler());
    // TODO Auto-generated method stub
    getContentResolver().registerContentObserver(Contacts.CONTENT_URI, false, observer);
    super.onCreate();
}

@Override
public IBinder onBind(Intent intent) {
    // TODO Auto-generated method stub
    return null;
}
}

Then you will notify when ever contact data is changed.
