在生产构建离子3中没有获得本地通知的声音

Question

我有Ionic 3局部通知声音的问题。当我进行调试时，声音即将到来。

它不是在生产构建中进行的，我也尝试将声音值设置为" res：//platform_default"（无法获得声音）。请帮我。预先感谢。

我的代码下方。

import {Component} from '@angular/core';
import {IonicPage, NavController, NavParams, Platform, AlertController} from 'ionic-angular';
import {LocalNotifications} from '@ionic-native/local-notifications';
@IonicPage()
@Component({
    selector: 'page-notifications',
    templateUrl: 'notifications.html',
})
export class NotificationsPage {
    data = {title: '', description: '', date: '', time: ''};
    constructor(public navCtrl: NavController,
                public localNotifications: LocalNotifications,
                public platform: Platform,
                public alertCtrl: AlertController) {
    }
    submit() {
        console.log(this.data);
        var date = new Date(this.data.date + " " + this.data.time);
        console.log(date);
        this.localNotifications.requestPermission().then((permission) => {
            this.localNotifications.schedule({
                id: 0,
                text: 'Delayed ILocalNotification',
                trigger: {at: date},
                foreground:true,
                vibrate: true,
                led: {color: '#FF00FF', on: 500, off: 500},
                data: {mydata: 'My hidden message this is'},
                // sound: 'res://platform_default',
                sound: this.setSound(),
            });
            let alert = this.alertCtrl.create({
                title: 'Congratulation!',
                subTitle: 'Notification setup successfully at ' + date,
                buttons: ['OK']
            });
            alert.present();
            this.data = {title: '', description: '', date: '', time: ''};
        });
    }
    setSound() {
        if (this.platform.is('android')) {
            return 'file://assets/sounds/Rooster.mp3'
        } else {
            return 'file://assets/sounds/Rooster.caf'
        }
    }
}

在仪表板页面

this.localNotifications.on('click').subscribe(
            (datas: any) => {
                alert('in_is');
                alert(JSON.stringify(datas));
                /*let alert = alertCtrl.create({
                    title: notification.title,
                    subTitle: json.mydata
                });
                alert.present();*/
            });

尝试使用 ternary 操作员分配MP3声音，而无需调用该函数分配

 this.localNotifications.schedule({
                id: 0,
                text: 'Delayed ILocalNotification',
                trigger: {at: date},
                foreground:true,
                vibrate: true,
                led: {color: '#FF00FF', on: 500, off: 500},
                data: {mydata: 'My hidden message this is'},
                sound: this.platform.is('android') ? 'file://assets/sounds/Rooster.mp3' : 'file://assets/sounds/Rooster.caf',
            });
