【问题描述】：

我是 monaca/cordova 的新手，我正在尝试使用 React 框架和这个插件获得带有声音的背景通知：https://github.com/katzer/cordova-plugin-local-notifications。我正在 android 10 设备中构建应用程序。当我尝试没有声音的通知时，它可以正常工作，但是在添加声音时，它会崩溃。这是错误的日志：

这是我用来获取通知的功能（如果不添加声音，可以正常工作）。

 const showNotification = () => 
    document.addEventListener("deviceready", onDeviceReady, false);
    function onDeviceReady() 
      console.log(cordova.plugins.notification.local.schedule);
    
   cordova.plugins.notification.local.schedule(
      id: 1,
      title: "Alarm Time",
      text: String(value),
      trigger:  at: value ,
      sound: "file://assets/songs/samplesong.mp3" // <-- this is where the error occurs. 
    );
  ;

*（value 是用户选择的 Date()）。

这是我的config.xml 文件：

【参考方案1】：

尝试用一个“/”写路径：

sound: "file:/assets/songs/samplesong.mp3"
