Question

我正在使用自定义声音通知功能。自定义声音在版本8以下的iOS和Android上正常运行。通知也到达所有版本的Android中。但是，自定义声音在android 8和9上不起作用。我还创建了一个通道ID。

下面，我分享了我的代码。谁能帮帮我吗？预先感谢。

  async checkPermission() {
    const enabled = await firebase.messaging().hasPermission();
    if (enabled) {
        this.getToken();
      } else {
        this.requestPermission();
     }
    let channel = new firebase.notifications.Android.Channel(
      "channelId",
      "Channel Name",
      firebase.notifications.Android.Importance.Max
    ).setDescription("A natural description of the channel");
    firebase.notifications().android.createChannel(channel);


    firebase
      .notifications()
      .getInitialNotification()
      .then(notificationOpen => {
        if (notificationOpen) {
          const action = notificationOpen.action;
          const notification = notificationOpen.notification;
        }
      });

    // the listener returns a function you can use to unsubscribe
    this.unsubscribeFromNotificationListener = firebase
      .notifications()
      .onNotification(notification => {

        if (Platform.OS === "android") {
          const channel = new firebase.notifications.Android.Channel(
            "channelId",
            "Channel Name",
            firebase.notifications.Android.Importance.Max
          )
            .setDescription("A natural description of the channel")
            .setSound(
              notification.data.sound ? notification.data.sound : "default"
            );

          firebase.notifications().android.createChannel(channel);

Answer 1

尝试一下。

首先将声音文件放置在res / raw文件夹中，并在通知通道中包含setSound（），

第二点，多亏了@PatelDhara，还要确保从设备中删除您的应用，以便新的频道配置能够正常工作。

然后将其放在代码行下面，对我来说很好用。

首先创建频道。

const channel = new firebase.notifications.Android.Channel(name, Description, firebase.notifications.Android.Importance.High)
.setDescription(ChannelName)
.setSound(default.mp3) //Set audio here
...
firebase.notifications().android.createChannel(channel);

然后：

const notification = new firebase.notifications.Notification()
.setNotificationId(id)
.setTitle(title)
.setSound(channel.sound); //Get sound from channel and set in notification builder

notification
.android.setChannelId(channel.channelId)
firebase.notifications().displayNotification(notification);

还要确保每当获得有效负载时，位于res / raw文件夹中的音频文件名和要获得有效负载的声音值都应该相同。

赞：

{
    "to" : "DEVICE-TOKEN",

    "notification" : {
      "body"  : "NOTIFICATION BODY",
      "title" : "NOTIFICATION TITILE",
      "sound" : "default"
    }
  }

注意：在响应本机中，Android O在0.56.0之前的版本（反应本机版本）中存在问题，因此请尝试升级您的版本。

Answer 2

花了一整天后，我找到了解决方案。我刚刚清除了应用数据，然后重新启动了手机，一切正常。

有一个问题，因为我在特定类型的通知上使用了自定义声音。

我还通过了有效负载中的频道ID，以在应用程序为后台和终止模式时根据通知的类型获得不同的声音。

{
    "to" : "DEVICE_TOKEN",

    "notification" : {
      "body"  : "NOTIFICATION BODY",
      "title" : "NOTIFICATION TITILE",
      "sound" : "default", //change your sound based on your requirement
      "android_channel_id":"CHANEEL_NAME", 
    }
  }

react-native-firebase自定义声音不适用于android 8，android 9
