无法使用phonegap 2.4在Android上播放录音(unable to play audio recordings on android using phonegap 2.4)

 我试图在phonegap中使用Media对象录制音频文件，然后播放它。 我没有问题录制，但是当我尝试播放它时，我的应用程序关闭，在我的模拟器和我的设备上。 在logcat上它说：“org.apache.cordova.readyPlayer（AudioPlayer.java）中的空指针异常”。 非常感谢愿意帮助我的人，我花了一段时间才意识到我完全迷失在这里。 这是我从http://docs.phonegap.com/en/2.4.0/cordova_media_media.md.html#media.stopRecord复制的代码，并在.stopRecord（）之后添加了.play（）。 如果需要，我可以添加清单和活动，我怀疑问题是否存在，但我可能是错的。 index.html的： 
 
<script type="text/javascript" charset="utf-8" src="cordova-2.4.0.js"></script>
<script type="text/javascript" charset="utf-8">

// Wait for Cordova to load
//
document.addEventListener("deviceready", onDeviceReady, false);

// Record audio
// 
function recordAudio() {
    var src = "myrecording.amr";
    var mediaRec = new Media(src, onSuccess, onError);

    // Record audio
    mediaRec.startRecord();

    // Stop recording after 10 sec
    var recTime = 0;
    var recInterval = setInterval(function() {
        recTime = recTime + 1;
        setAudioPosition(recTime + " sec");
        if (recTime >= 10) {
            clearInterval(recInterval);
            mediaRec.stopRecord();
            document.getElementById('audio_position').innerHTML = "finished";
            **mediaRec.play();**
        }
    }, 1000);
}

// Cordova is ready
//
function onDeviceReady() {
    recordAudio();
}

// onSuccess Callback
//
function onSuccess() {
    console.log("recordAudio():Audio Success");
}

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

// Set audio position
// 
function setAudioPosition(position) {
    document.getElementById('audio_position').innerHTML = position;
}

</script>
 
 
<p id="media">Recording audio...</p>

im trying to record an audio file using Media object in phonegap and then play it. i have no problem recording, but then when i try to play it my app shuts down, both on my emulator and my device. on the logcat it says: "null pointer exception at org.apache.cordova.readyPlayer (AudioPlayer.java)". many thanks to anyone who is willing to help me, it took me a while to realize im completely lost here. here is the code which i copied from http://docs.phonegap.com/en/2.4.0/cordova_media_media.md.html#media.stopRecord and added .play() after the .stopRecord(). i can add the manifest and activity if needed, i doubt that the problem is there but i could be wrong. index.html:
 
<script type="text/javascript" charset="utf-8" src="cordova-2.4.0.js"></script>
<script type="text/javascript" charset="utf-8">

// Wait for Cordova to load

    // Record audio
    mediaRec.startRecord();

    // Stop recording after 10 sec
    var recTime = 0;
    var recInterval = setInterval(function() {
        recTime = recTime + 1;
        setAudioPosition(recTime + " sec");
        if (recTime >= 10) {
            clearInterval(recInterval);
            mediaRec.stopRecord();
            document.getElementById('audio_position').innerHTML = "finished";
            **mediaRec.play();**
        }
    }, 1000);
}

// Cordova is ready

    recordAudio();

    console.log("recordAudio():Audio Success");
}

// onError Callback

    alert('code: '    + error.code    + '\n' +

}

function setAudioPosition(position) {
    document.getElementById('audio_position').innerHTML = position;
}
