问题与疑问

我正在尝试让基于Cordova的安卓应用播放下载到设备内部存储/Music目录的音频文件，downloadAudio函数可以正常将文件保存到该目录（尽管文件插件文档称该位置为SD卡，但实际设备并非如此），存在以下疑问：

media插件能否从file:///storage/emulated/0/Music/[file].mp3路径播放音频？似乎需要cdvfile格式路径，但不确定cdvfile是否支持该外部位置，怀疑它仅适用于应用内部路径？
编辑： 若引用无效路径会提示文件不存在，无此错误说明media插件可识别文件，但修正语法错误后出现“Code 1, Prepare failed.: status=0x1”错误，相关讨论虽有关联但无法理解。
无法使用URL转换方法（如toURL返回TypeError: fileTransferInternalUrl.toURL is not a function）生成适用于media插件的cdvfile路径，均报错。
编辑： 尽管toURL无效，但文件URL似乎可正常工作。
若media插件不支持播放应用外部路径的音频，能否使用copyTo（覆盖已有文件）将外部文件复制到media插件可访问的应用临时内部目录？（新版文件插件文档中copyTo的文档缺失，使用时也报错，若可行可提供更多细节）
尝试过相关方案及官方示例均无效。
未收到权限相关错误，若存在权限问题，下载功能应无法正常工作（了解安卓权限有变更）。

按建议修改toURL后可返回URL，但出现以下错误，似乎media播放器无法使用该URL：
Media播放器错误：Code 1, AudioPlayer.onError(1, -2147483648) [未知错误]
控制台错误：

附带函数代码：

function downloadAudio (fileTransferWebUrl,thisElement) {
    fileTransferWebUrl = encodeURI(fileTransferWebUrl);
    if (isAndroidApp == true) {
        var fileNameMP3Array = fileTransferWebUrl.split("/");
        var fileNameMP3 = fileNameMP3Array[fileNameMP3Array.length-1]; //get file name from web URL
        fileTransferInternalUrl = cordova.file.externalRootDirectory + 'Music/' + fileNameMP3; //  file:///storage/emulated/0/Music/[file].mp3
    }
    try {
        fileTransfer.download(
            fileTransferWebUrl, 
            fileTransferInternalUrl, 
            function (entry) {
                alert('Download complete to Music/' + fileNameMP3);
            },
            function(error){ //error
                alert("Download error source " + error.source + " download error target " + error.target + " download error code " + error.code + " http_status " + error.http_status + " body " + error.body + " exception " + error.exception);
            },
            true, //trust all hosts. safer to be false, set to true accepts all security certificates, not recommended for production use
        );
    }
    catch (e) {
        alert(e);
    }
}

function playDownloadedAudio (fileTransferWebUrl, thisElement) {
    var nativePath = "";
    fileTransferWebUrl = encodeURI(fileTransferWebUrl);
    if (isAndroidApp == true) {
        var fileNameMP3Array = fileTransferWebUrl.split("/");
        var fileNameMP3 = fileNameMP3Array[fileNameMP3Array.length-1]; //get file name from web URL
        fileTransferInternalUrl = cordova.file.externalRootDirectory + 'Music/' + fileNameMP3; //cordova.file.externalRootDirectory
        alert(fileTransferInternalUrl); // file:///storage/emulated/0/Music/A_casa_vete_y_cuenta_alli.mp3
    }
    resolveLocalFileSystemURL(cordova.file.dataDirectory + fileNameMP3, function (entry) {
        nativePath = entry.toURL(); 
        console.log("cordova.file.dataDirectory + fileNameMP3 = " + cordova.file.dataDirectory + fileNameMP3 + " | nativePath = " + nativePath);
        if (my_media != null) { 
            my_media.release(); // clean up old file
        }
        my_media = new Media(nativePath,
            function () //success;
            { }, 
            function (error) //error
            { 
                alertOK(translate('Error in playback. Please contact support. \n Code: ','text') + error.code + '\n '+translate('Message:','text')+' '+error.message + '\n');
                playing = false;
            }
        );
        my_media.play();
    });
}
