我只是複製Android提供的示例同步應用程序中使用的代碼（找到here）。Android帳戶同步給我一個類未找到錯誤...但它不應該
所以它應該工作......但是當我安裝到我的手機，我得到印刷以下錯誤：

它說AuthenticatorService類不包括在我的包中找到......我有一個延伸服務AuthenticatorService類：
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();
}
}
這裏是清單：

直接從示例代碼。有沒有人有獲得帳戶工作的經驗？如有必要，我可以提供更多代碼，但只需從Android提供的示例代碼中逐行重寫即可。運行這個的設備在2.1上。謝謝！
你的AndroidManifest.xml中有什麼？ –
我現在將它添加到帖子中。它直接來自示例應用程序，當然包也會相應更改。 – JMRboosties
