Question

编辑：我忘了告诉我，我已经尝试在onRefreshToken上创建一个断点，并在该函数中创建一个Log，但是当我启动应用程序时，它们都没有运行（断点没有运行）。启动，并且Log不会显示在AS的控制台日志中）。因此，IMO的纯粹目的是不会启动服务本身。

我编写了一个代码，如果onMessageReceived中有数据传入，我的应用程序将在其中显示通知。 它可以很好地运行，没问题，直到我在Android Jelly Bean中尝试。

通知没有显示（我确定已发送通知，因为另一个非JellyBean设备同时显示了通知。），然后我尝试了KitKat设备，结果相同。

然后我尝试对其进行调试，并且在Android Studio中没有显示错误（我敢打赌，因为该设备安装了中文rom并且没有内置Google Play服务）。

稍后，我更改了方法并在Emulator中尝试，然后显示E/FirebaseInstanceId: Token retrieval failed: PHONE_REGISTRATION_ERROR。我已经在安装了KitKat和JellyBean映像的模拟器中尝试过，结果是相同的，出现相同的消息。

这是我的代码：
