Question

我正试图以.wav格式（未压缩）在Android中录制音频。我正在开发一个phonegap应用程序，所以我在这里使用了已经可用的插件 - https://github.com/petrica/wav-recorder

我按原样导入了插件。下面是我的index.html文件

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

    // Record audio
    // 


    // PhoneGap is ready
    //
    function onDeviceReady() {
        //recordAudio();
        //playAudio();
        recordWav();
    }

    // status callback 
var statusCallback = function (mediaStatus, error)
{
  if (martinescu.Recorder.STATUS_ERROR == mediaStatus) {
    alert(error);
  }
}

// buffer callback
var bufferCallback = function (buffer)
{
  console.log(buffer);
}

function recordWav()
{
    var recorder = new martinescu.Recorder('/record1234556.wav', { sampleRate: 22050 }, statusCallback, bufferCallback);
    recorder.record();

     // Stop recording after 10 sec
        var recTime = 0;
        var recInterval = setInterval(function() {
            recTime = recTime + 1;
            setAudioPosition(recTime + " sec");
            if (recTime >= 10) {
                clearInterval(recInterval);
             recorder.stop();

            }
        }, 1000);
}

    // 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>
  </head>
  <body ng-app="starter">
    <ion-pane>
      <ion-header-bar class="bar-stable">

          <p id="audio_position"></p>
      </ion-content>
    </ion-pane>
  </body>

</html>

但问题是，我无法运行，因为我收到错误02-18

02-18 13:43:30.899: E/ro.martinescu.audio.ExtAudioRecorder(21158): /record1234556.wav: open failed: EROFS (Read-only file system)

我只尝试了record1234556.wav而不是/record1234556.wav，然后它说出了以下错误

02-18 13:44:18.229: E/ro.martinescu.audio.ExtAudioRecorder(21569): /storage/emulated/0record1234556.wav: open failed: EACCES (Permission denied)

以下是我的AndroidManifest

<?xml version='1.0' encoding='utf-8'?>

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
    <uses-sdk android:minSdkVersion="14" android:targetSdkVersion="22" />
</manifest>

这里真的有什么不对？
