「聯繫人」是否可通過仿真器使用？

Question

在我的代碼中，我試圖訪問聯繫人的地方（在模擬器中，所以是的，真的沒有聯繫人訪問，但我認爲它會「僞造」一些製造的），我的應用程序翻轉或觸發器在進入Debug透視圖中的Eclipse和logcat的告訴我：

應用：com.google.process.gapps 標籤：GTalkService 文字：EVENT_GSERVICES_CHANGED：NO GTALK連接！

如果這是預期的，那麼解決方法是什麼？ 如果不能預期，我的失敗會是什麼？

按照要求，我的代碼截至目前：

      AlertDialog.Builder builder = new AlertDialog.Builder(this);

      builder.setPositiveButton("OK", null);
