Expo Client 中的 Android 推送通知没有声音或振动

Question

嗨，我是本地反应新手，我只是在 Android 上测试推送通知。但是当我通过 expo 客户端在我的 Android 设备上测试时没有振动或声音。

然而，当我通过 expo 客户端在 Android 设备上打开应用程序时，推送通知确实出现了，但没有声音，没有振动，即使我已经将它们设置为 true。

我想发出通知，而不是每天早上 8 点通知用户，即使应用程序已关闭，我可以做到吗？

async componentWillMount() {
    let result = await Permissions.getAsync(Permissions.NOTIFICATIONS);
    if (result.status === "granted" && this.state.switchStatus) {
      console.log("Notification permissions granted.");
      this.setNotifications();
    } else {
      console.log("No Permission", Constants.lisDevice);
    }

    this.listenForNotifications();
  }
  getNotification(date) {
    const localNotification = {
      title: `Notification at ${date.toLocaleTimeString()}`,
      body: "N'oubliez pas de prendre tes medicament",
      ios: {

        sound: true 
      },

      android: {
        sound: true, 
        priority: "max", 
        sticky: false, 
        vibrate: true 
      }
    };
    return localNotification;
  }
  setNotifications() {
    Notifications.cancelAllScheduledNotificationsAsync();

    for (let i = 0; i < 64; i++) {
      //Maximum schedule notification is 64 on ios.
      let t = new Date();
      if (i === 0) {
        t.setSeconds(t.getSeconds() + 1);
      } else {
        t.setMinutes(t.getMinutes() + 1 + i * 1);
      }
      const schedulingOptions = {
        time: t 
      };
      Notifications.scheduleLocalNotificationAsync(
        this.getNotification(t),
        schedulingOptions
      );
    }
  }
  listenForNotifications = () => {
    Notifications.addListener(notification => {
      console.log("received notification", notification);
    });
  };

我找到了声音和振动的解决方案，这不是最好的，正如我所说，我是 RN 新手，但它仍然有效（我使用了这个：“创建 Android 异步频道”）

async componentWillMount() {
    let result = await Permissions.getAsync(Permissions.NOTIFICATIONS);
    if (result.status === "granted" && this.state.switchStatus) {
    // i add this :
      if (Platform.OS === 'android') {
  Notifications.createChannelAndroidAsync('chat-messages', {
    name: 'Chat messages',
    sound: true,
    vibrate: true,
  });
}
      console.log("Notification permissions granted.");

      this.setNotifications();
    } else {
      console.log("No Permission", Constants.lisDevice);
    }

    this.listenForNotifications(); 
  }

  getNotification(date) {

    const localNotification = {
      title: `Notification at ${date.toLocaleTimeString()}`,
      body: "N'oubliez pas de prendre tes medicament", 
      ios: {

        sound: true 
      },

      android: {
       "channelId": "chat-messages" //and this
            }
    };
    return localNotification;
  }
  setNotifications() {
    Notifications.cancelAllScheduledNotificationsAsync();

    for (let i = 0; i < 64; i++) {
      //Maximum schedule notification is 64 on ios.
      let t = new Date();
      if (i === 0) {
        t.setSeconds(t.getSeconds() + 1);
      } else {
        t.setMinutes(t.getMinutes() + 1 + i * 1); // 15 Minutes
      }
      const schedulingOptions = {
        time: t 
      };
      Notifications.scheduleLocalNotificationAsync(
        this.getNotification(t),
        schedulingOptions
      );
    }
  }
  listenForNotifications = () => {
    Notifications.addListener(notification => {
      console.log("received notification", notification);
    });
  };
