我知道网上有很多关于这个话题的类似问题，但我觉得我做了每个人所说的一切。当我说
final String regId = GCMRegistrar.getRegistrationId(this);
它正在回馈一个 amty 字符串。但后来在我的 LogCat 中，它指出该设备确实是使用 regId 注册的。
这是我的代码：

// Device is already registered on GCM

// Skips registration.
Toast.makeText(getApplicationContext(), "Already registered with GCM", Toast.LENGTH_LONG).show();

我在本教程的帮助下构建了这个应用程序
任何帮助将不胜感激！！提前Tnx！
PS：我知道这里有一些我目前不使用的代码。它是为了将来的目的
