使用 Parse.com 的示例代码推送通知不起作用

Question

过去两天我一直在使用 parse.com 的推送通知，但无法正常工作。

我从 parse.com 下载了示例代码并做了一些小改动。在我的 parse.com 仪表板上，我可以看到该应用程序已注册。当我通过仪表板发送推送通知时，我会收到一条成功消息，但我的 Android 模拟器上没有收到通知。

这是清单文件：

            </intent-filter>
        </receiver>

    </application>

</manifest>

这是应用程序类

public class StarterApplication extends Application
{
  @Override
  public void onCreate()
  {
    super.onCreate();

    Parse.initialize(this, "xxxx", "yyy");

    ParseInstallation installation = ParseInstallation.getCurrentInstallation();
    installation.put("email", "jpc@acme.com");
    installation.saveInBackground();

    ParsePush.subscribeInBackground("Emulator1", new SaveCallback()
    {
      @Override
      public void done(ParseException e)
      {
        if (e != null)
          Log.d("#### DEBUG", "Parse subscription failed with error: " + e.toString());
        else
          Log.d("#### DEBUG", "Subscribed to parse");
      }
    });
  }
}

有人可以帮忙吗？ TIA

解析推送通知需要 Google Play 商店和用户在 Android 模拟器中登录 Play 商店才能工作。按照平台和模拟器的具体说明启用 google play store。
