如何解决当cordova-plugin-local-notification尝试播放mp3文件时，Monaca Android应用程序崩溃
我是monaca / cordova的新手，我正在尝试使用React框架和此插件https://github.com/katzer/cordova-plugin-local-notifications来获取声音的背景通知。我正在Android 10设备上构建该应用程序。当我尝试不带声音的通知时，它工作正常，但是添加声音时，它崩溃了。这是错误的日志：

这是我用来获取通知的功能（如果未添加声音，则效果很好）。
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：

非常感谢您的帮助，并在此先感谢您。
解决方法
尝试用一个“/”写路径：
sound: "file:/assets/songs/samplesong.mp3"
