那些遇到过的问题

Firebase云消息传递 - onMessageReceived无法正常工作

Laz*_*olj 13 java android firebase firebase-cloud-messaging

我想在我的应用中制作一个简单的通知功能.我按照此 YouTube视频和这两个Firebase文档网址1和2以及Android Studio中的Firebase工具助手(说我已连接到Firebase).出于某种原因,在我的旧应用程序(下面发布的代码)上执行这些步骤和文档后,它将不允许我接收通知.但是,如果我在一个全新的应用程序上执行相同的步骤,它将完美地运行.我在后台,活动和终止状态下测试了同一物理设备和环境中的两个应用程序.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.两者均未经过设备ID测试.我甚至没有得到任何错误日志或任何TAG日志.我认为我的一个编译项目是干扰的,不确定究竟是什么,但我可能要看那里.

我还检查了所有这些SO帖子:1 2 3及更多

PS.我在下面删除了我的包名,我在FireBase上多次检查并且它们匹配,所以我知道这不是问题.但是,我的新演示应用程序的FireBase显示我的应用程序连接但我的旧应用程序的FireBase没有.此外,我之前已经设置了赏金,但仍然遇到同样的问题.

这是我有问题的代码:

Notification.java(它的文档要求的服务)

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());
}

如果您正在接收设备令牌并且您有服务器api密钥,那么请检查您的代码是否正常工作或不使用 pushtry.如果你的代码中有任何错误,它会给出无效注册,404错误等错误.对于FCM的实施,您可以按照本教程 - FCM教程

还有一两件事,我曾注意到在你的build.gradle文件中没有任何applicationId "Package Name"的defaultConfig.我不确定,但这是包名,并在我们在firebase控制台上创建项目时使用(带包的项目名称)

由于Android Oreo新通知模型需要指定频道定义以构建和显示通知,因此很可能您的通知未显示.同样在您的app.gradle中,您的目标是Android 版本26,这是Android Oreo,因此您必须以下列方式实现以下代码.

它很容易采用.你需要做的就是:

1.在YourApplicationClass.onCreate()中定义通知通道

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {

            NotificationChannel chan1 = new NotificationChannel(
                YOUR_DESIRED_CHANNEL_ID_STRING,
                YOUR_DESIRED_CHANNEL_LABEL_STRING, 
                NotificationManager.IMPORTANCE_DEFAULT);

            chan1.setDescription(YOUR_DESIRED_CHANNEL_DESC_STRING);//OPTIONAL
            chan1.setLightColor(Color.BLUE);//OPTIONAL     
            chan1.setLockscreenVisibility(Notification.VISIBILITY_PUBLIC);//OPTIONAL
            chan1.setShowBadge(true);//OPTIONAL

            getManager().createNotificationChannel(chan1);
        }

2.使用此构造函数替换通知构建器

    NotificationCompat.Builder builder=
new NotificationCompat.Builder(this, YOUR_DESIRED_CHANNEL_ID_STRING);

很高兴知道您可以定义多个具有针对Android Oreo及更高版本的不同属性的频道

如果您查看此文档， 您似乎没有扩展FirebaseInstanceIdService来管理令牌创建/轮换的服务。这是一个示例代码。此类接收将推送通知发送到特定设备所需的令牌。

好吧，这个错误现在困扰着我。我查看了您的依赖关系树，发现您正在重复其中一些。例如，您有三个版本：

也许您应该将其清除为最新版本，或者将其与工作版本相匹配。另外，您正在使用新的 gradle 插件，但您尚未更新您的依赖项以在大多数情况implementation下使用compile，也许也可以尝试一下？这就是为什么你应该这样做。
