【问题描述】：
我想在我的应用中创建一个简单的通知功能。我关注了 this YouTube 视频以及这两个 Firebase 文档 URL 1 和 2 以及 Android Studio 中的 Firebase 工具助手（表示我已连接到 Firebase）。出于某种原因，按照我的旧应用程序上的这些步骤和文档（代码发布在下面），它不允许我接收通知。但是，如果我在一个全新的应用程序上遵循相同的步骤，它就可以完美运行。我在后台、活动和终止状态下在相同的物理设备和环境中测试了这两个应用程序。每次我创建的新演示应用程序都可以正常工作，但我想要通知的旧应用程序不起作用。两者都在没有获得设备 ID 的情况下进行了测试。我什至没有收到任何错误日志或任何 TAG 日志。我认为我编译的项目之一有干扰，不确定到底是什么，但我可能需要看看那里。
附言。我在下面删除了我的包名称，我在 FireBase 上检查了多次，它们匹配，所以我知道这不是问题。但是，我的新演示应用程序的 FireBase 显示我的应用程序已连接，但我的旧应用程序的 FireBase 没有。另外，我之前设置了赏金，但仍然遇到同样的问题。
这是我有问题的代码：
Notification.java（它像文档要求的那样提供服务）
public class Notification extends FirebaseMessagingService {
public Notification() {
}
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
showNotification(remoteMessage.getData().get("message"));
Log.d("FMC", "Message Notification Body: " + remoteMessage.getNotification().getBody());
}
private void showNotification(String message) {
Intent i=new Intent(this, SplashScreen.class);
i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent=PendingIntent.getActivity(this,0,i,PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder builder=new NotificationCompat.Builder(this)
.setAutoCancel(true)
.setContentTitle("FCM TITLE").setContentText(message)
.setSmallIcon(R.drawable.pt_icon)
.setDefaults(android.app.Notification.DEFAULT_ALL)
.setContentIntent(pendingIntent);
NotificationManager notificationManager= (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
notificationManager.notify(0,builder.build());
}
}
请注意，我什至没有在上面的 notification.java 中获得日志。

【问题讨论】：
-
它可能是我使用的编译库之一，不允许 me 与 Firebase 交互吗？*
-
从 Firebase 控制台发送时是否收到任何默认通知？
-
当您运行应用程序时，您会收到“Firebase 已成功初始化”的日志消息？
-
我没有收到任何通知，甚至没有收到“Firebase 已成功初始化”日志：/
-
你能显示你放置 json 文件的文件夹结构的屏幕截图吗？
