android - 为什么在 android 版本 10 中没有触发 onMessagedRecieved？

问题描述

当我收到 FCM 的通知时，我想开始一项活动。它在应用程序的前台运行良好，但是当我在 android 中移动我的活动时，我会在系统托盘中收到通知。

正如我所做的那样，当应用程序位于前台时会调用 onMessagereceived，但当应用程序位于后台时不会调用它。

    class MyFirebaseMessagingService : FirebaseMessagingService() {

    // [START receive_message]
    private var mRemoteMessage: Map<String, String>? = null

    override fun onMessageReceived(remoteMessage: RemoteMessage) {


        // Check if message contains a data payload.
        if (!remoteMessage.data.equals("")) {
            Log.d(TAG, "Message data payload: " + remoteMessage.getData());
        }

        // Check if message contains a notification payload.
        if (remoteMessage.getNotification() != null) {
            Log.d(TAG, "Message Notification Body: " + remoteMessage.getNotification()!!.getBody());
            remoteMessage.data.get("notification_data")?.let { sendNotification(it) };

            val broadcast = Intent();
            broadcast.setAction("OPEN_NEW_ACTIVITY")
            sendBroadcast(broadcast)
        }

    }

    private fun sendNotification(messageBody: String) {
        val intent = Intent(this, NotificationActivity::class.java)
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)
        val pendingIntent = PendingIntent.getActivity(
            this, 0, intent,
            PendingIntent.FLAG_ONE_SHOT
        )

        val channelId = getString(R.string.default_notification_channel_id)
        val defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION)
        val notificationLayoutExpanded = RemoteViews(packageName, R.layout.activity_notify)

        val notificationBuilder = NotificationCompat.Builder(this, channelId)
            .setSmallIcon(R.drawable.ic_launcher)
            .setContentTitle(getString(R.string.fcm_message))
            .setContentText(messageBody)
            .setAutoCancel(true)
            .setSound(defaultSoundUri)
            .setContentIntent(pendingIntent)
            .setFullScreenIntent(pendingIntent,true)
            .setCustomBigContentView(notificationLayoutExpanded)
            .setStyle(NotificationCompat.DecoratedCustomViewStyle())

        val notificationManager = getSystemService(Context.NOTIFICATION_SERVICE)
                as NotificationManager

        // Since android Oreo notification channel is needed.
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            val channel = NotificationChannel(
                channelId,
                "Channel human readable title",
                NotificationManager.IMPORTANCE_HIGH
            )
            notificationManager.createNotificationChannel(channel)
        }

        notificationManager.notify(0, notificationBuilder.build())

 }

请建议在后台收到通知时我该怎么做才能启动活动。？

解决方案

您在通知中发送了数据。通知仅处理应用程序的前台，而不是您在有效负载中发送数据的通知。并基于有效负载消息打开活动

    override fun onMessageReceived(remoteMessage: RemoteMessage) {
    super.onMessageReceived(remoteMessage)       
    val data = remoteMessage.data
    if (remoteMessage.data.isNotEmpty()) {
       Log.d(TAG_FIREBASE, "Message data payload: ${remoteMessage.data}")

      //open activity
  }}

而且还取决于您测试此服务的设备
