Question

我是phoneGap的新手，目前我有媒体库播放音频的问题

我已按照步骤启用媒体插件但不起作用。

cordova插件rm cordova-plugin-media cordova插件rm cordova-plugin-media-capture

cordova插件rm cordova-plugin-extension cordova插件rm cordova-plugin-file

phonegap平台添加android

cordova平台更新android@5.0

cordova插件添加cordova-plugin-media cordova插件添加cordova-plugin-media-capture

这是我的代码audio.js。

// Audio player
//
var my_media = null;

// Play audio
//
function playAudio(src,callbackFinishCallBack) {
    // Create Media object from src
    if (typeof Media !== 'undefined') {
        // the variable is defined
        alert("Error No Media Object defined..!");
        return;
    }
    var my_media = null;
    my_media = new Media(src,  // success callback
            function () {
                my_media.release();
                if(typeof callbackFinishCallBack == 'function')
                {
                    callbackFinishCallBack.call(this);
                }
            },
            // error callback
            function (err) {
                 alert('code: ' + err.code + '\n' +
                    'message: ' + err.message + '\n');
                my_media.release();
                if(typeof callbackError == 'function')
                {
                    callbackError.call(this);
                }  
            });

    // Play audio
    my_media.play();


}

/*function playAudio(src,callbackFinishCallBack) {
 // HTML5 Audio
    if (typeof Audio != "undefined") { 
        var audioRes = new Audio(src).play() ;
        alert("Called audio");
        audioRes.addEventListener('onended', function(){
            alert();
            callbackFinishCallBack.call(this);
        });

    // Phonegap media
    } else if (typeof device != "undefined") {
        alert("Called Media");

        if (typeof Media !== 'undefined') {
            // the variable is defined
            alert("Error No Media Object Defnied");
            return;
        }

        // Android needs the search path explicitly specified
        if (device.platform == 'Android') {
            src = '/android_asset/www/' + src;
        }

        var mediaRes = new Media(src,
            function onSuccess() {
                my_media.release();
                if(typeof callbackFinishCallBack == 'function')
                {
                    callbackFinishCallBack.call(this);
                }
            },
            function onError(e){
                console.log("error playing sound: " + JSON.stringify(e));
            });
        mediaRes.play();

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

我只是在这里使用设备就绪代码。的index.html

 function onDeviceReady() 
    {
$.ajax({
           type: "POST",
           url: "http://erronak.com/dev/child_app/index.php",
           dataType:'json'
        }).done(function( row ) {

          $("#main_image").attr("src",row.image);
          $("#popup_name").html(row.name);
          $("#audio_hidden").val(row.audio);


          //Start replacing operation..
          //stopAudio();
          //alert(row.audio);
          playAudio( row.audio,function(){
            //Let Display text over here..
            $( "#popup_name" ).popup( "open" );

          });

这是我的主要配置文件config.xml

当在代码上面运行它给我错误没有定义媒体对象..！

我已经尝试过这么多我非常接近解决方案，请帮我出来..

Answer 1

用以下代码替换playAudio函数。

function playAudio（src，callbackFinishCallBack）{

var my_media = null;
my_media = new Media(src,  // success callback
        function () {
            my_media.release();
            if(typeof callbackFinishCallBack == 'function')
            {
                callbackFinishCallBack.call(this);
            }
        },
        // error callback
        function (err) {
             alert('code: ' + err.code + '\n' +
                'message: ' + err.message + '\n');
            my_media.release();
            if(typeof callbackError == 'function')
            {
                callbackError.call(this);
            }  
        });

// Create Media object from src
if (typeof my_media !== 'undefined') {
    // the variable is defined
    alert("Error No Media Object defined..!");
    return;
}

// Play audio
my_media.play();

}

phonegap媒体对象未定义错误
