Question

我有以下有效负载推送通知，是从我的服务器发送的。通知适用于所有版本，但声音仅在Android Oreo上不起作用，其他Android版本也可以。

{
  "to" : "d4DLcrilLbs...",
   "notification" : {
   "body" : "This is an FCM notification message!",
   "title" : "FCM Message",
   "sound" : "new_sound.wav"
  }
}

Answer 1

在奥利奥中，您必须使用频道设置声音

请以此更改您的代码

 if(Build.VERSION.SDK_INT>=Build.VERSION_CODES.O)
    {
        final Uri alarmSound = Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE
                + "://" + this.getPackageName() + "/raw/notification");
        AudioAttributes attributes = new AudioAttributes.Builder()
                .setUsage(AudioAttributes.USAGE_NOTIFICATION)
                .build();
        NotificationChannel channel = new NotificationChannel("MyNotification","MyNotification", NotificationManager.IMPORTANCE_DEFAULT);
        channel.setSound(alarmSound,attributes);
        NotificationManager mgr =getSystemService(NotificationManager.class);
        mgr.createNotificationChannel(channel);

    }

它将在您的应用程序处于后台/前景状态下工作

Android oreo中的通知需要在频道下注册，否则您将无法生成通知。
