android - PhoneGap - 无法播放本地声音文件

Question

我在 Android 设备上使用 PhoneGap。

我正在尝试播放本地 .wav 文件，但遇到了一些错误。

我正在使用来自

的示例代码

http://docs.phonegap.com/en/1.0.0/phonegap_media_media.md.html

document.addEventListener("deviceready", onDeviceReady, false);

    // PhoneGap is ready
    //
    function onDeviceReady() {
        playAudio("sounds/menu-change.wav");
    }

    // Audio player
    var my_media = null;

    // Play audio
    function playAudio(src) {
        // Create Media object from src
        my_media = new Media(src, onSuccess, onError);

        // Play audio
        my_media.play();
    }


    function onSuccess() {
        console.log("playAudio():Audio Success");
    }

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

我收到以下错误

它说它需要媒体插件，但我在我的 config.xml 文件中启用了它

<plugin name="Media" value="org.apache.cordova.AudioHandler"/>

任何帮助将不胜感激。

谢谢

当使用位于 www 文件夹中的声音文件时，您需要在 Android 上使用以下文件路径格式:

new Media("/android_asset/www/{directory}/{file-name}.mp3");
