java - Firebase 云消息传递 - onMessageReceived 不工作

Question

我想在我的应用中添加一个简单的通知功能。我关注了this YouTube 视频和这两个 Firebase 文档 URL 1和 2加上 Android Studio 中的 Firebase 工具助手(它表示我已连接到 Firebase)。出于某种原因，在我的旧应用程序(代码发布在下面)上执行这些步骤和文档后，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执行相同的步骤，它就会完美运行。我在后台、 Activity 和终止状态下在同一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没有问题，但我想要通知的旧应用程序不起作用。两者均在未获取设备 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，但我可能必须去那里看看。

我还检查了所有这些 SO 帖子:1 2 3等等

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所在。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(它是文档要求的服务)

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());
}
}

Notice I do not even get a log in the notification.java above.

Answer 1

如果您正在接收设备 token 并且您有服务器 api key ，请使用 pushtry 检查您的代码是否正常工作.如果您在代码中犯了任何错误，它会给出类似无效注册、404 错误 等错误。对于 FCM 的实现，您可以按照本教程- FCM Tutorial

我还注意到在您的 build.gradle 文件中，defaultConfig 中没有任何 applicationId "Package Name"。我不确定，但这是包名称，当我们在 firebase 控制台上创建项目时使用(带包的项目名称)
