Android Account Sync giving me a class not found error... but it shouldn't

I simply copied the code used in the sample sync app provided by Android (found here).

So it should work... but when I install it onto my phone I get the following error printed:

It says the AuthenticatorService class is not found in my package... I have an AuthenticatorService class which extends Service:

package com.test.sync;

import android.app.Service;
import android.content.Intent;
import android.os.IBinder;

public class AuthenticationService extends Service {

        private Authenticator mAuthenticator;

        @Override
        public void onCreate() {
            mAuthenticator = new Authenticator(this);
        }       

        @Override
        public IBinder onBind(Intent arg0) {
            return mAuthenticator.getIBinder();
        }


}

Straight from the sample code. Does anyone have experience with getting accounts to work? I can provide more code if necessary, but it's simply just rewritten line by line from the sample code provided by Android. The device running this is on 2.1. Thanks!

Your AndroidManifest.xml declares

android:name=".authenticator.AuthenticationService"

Your AuthenticatorService.java is in the com.test.sync package and implements AuthenticationService, so it's in com.test.sync.AuthenticationService.

You should remove .authenticator from your manifest.
