Question

我已将声音文件（ tictac.mp3 ）放入根目录（index.html）

我使用这个功能：

function playAudio(src) {
    console.log("playAudio "+src);
    var media = new Media(src, onSuccess, onError);
    media.play({numberOfLoops: 1}); 
}
function onSuccess() {
    console.log("playAudio():Audio Success");
}

function onError(error) {
    console.log('code: ' + error.code + '\n' + 'message: ' + error.message + '\n');
}

并致电playAudio("tictac.mp3");

我的Android和我的应用程序上没有任何声音，我的应用程序登录我的机器人只是给了我：

playAudio tictac.mp3

根本没有声音！，没有成功也没有错误

我的config.xml包含以下行：

<feature name="http://api.phonegap.com/1.0/file"/>
<feature name="http://api.phonegap.com/1.0/media"/>
<feature name="http://api.phonegap.com/1.0/network"/>
<gap:plugin name="org.apache.cordova.media"  />

我做错了什么？

我也试过这段代码

function playAudio(src) {
    console.log("PlayAudio");
    if (typeof Audio != "undefined") { 
        new Audio(src).play() ;

    // Phonegap media
    } else if (typeof device != "undefined") {
        console.log("Phonegap media");
        // Android needs the search path explicitly specified
        if (device.platform == 'Android') {

            src = '/android_asset/www/' + src;
            console.log("Android", src);
        }

        var mediaRes = new Media(src,
            function onSuccess() {
                // release the media resource once finished playing
                mediaRes.release();
            },
            function onError(e){
                console.log("error playing sound: " + JSON.stringify(e));
            });
        mediaRes.play();

    } else {
        console.log("no sound API to play: " + src);
    }
 }

我应该将cordoba.js或phonegap.js包含在我的项目中吗？

（我使用phonegap构建服务）
