捕获音频Phonegap错误代码3

Question

I'm creating an app with audio recording, i tried to implement this example code: http://docs.phonegap.com/en/3.3.0/cordova_media_capture_capture.md.html#capture.captureAudio 我正在创建一个带录音的应用程序，我试图实现这个示例代码： http ： //docs.phonegap.com/en/3.3.0/cordova_media_capture_capture.md.html#capture.captureAudio

But when click on the button an error appears: Code error 3. According to documentation this errors appears when you exit the recording aplicacion before you record anything, but when i click on the button the recording app is not launched it goes directly to error function. 但是当单击按钮时会出现错误：代码错误3.根据文档，当您在录制任何内容之前退出录制aplicacion时会出现此错误，但是当我单击按钮时，录制应用程序未启动它会直接转到错误功能。

Capture video works fine. 捕获视频工作正常。

Using Phonegap 3.0.0 or 2.9.0 with Phonegap Build. 使用Phonegap 3.0.0或2.9.0与Phonegap Build。

Code: 码：

<!DOCTYPE html>
<html>
<head>
<title>Capture Audio</title>

<script type="text/javascript" charset="utf-8" src="cordova.js"></script>
<script type="text/javascript" charset="utf-8" src="json2.js"></script>
<script type="text/javascript" charset="utf-8">

// Called when capture operation is finished
//
function captureSuccess(mediaFiles) {
    var i, len;
    for (i = 0, len = mediaFiles.length; i < len; i += 1) {
        uploadFile(mediaFiles[i]);
    }
}

// Called if something bad happens.
//
function captureError(error) {
    var msg = 'An error occurred during capture: ' + error.code;
    navigator.notification.alert(msg, null, 'Uh oh!');
}

// A button will call this function
//
function captureAudio() {
    // Launch device audio recording application,
    // allowing user to capture up to 2 audio clips
    navigator.device.capture.captureAudio(captureSuccess, captureError, {limit: 2});
}

// Upload files to server
function uploadFile(mediaFile) {
    var ft = new FileTransfer(),
        path = mediaFile.fullPath,
        name = mediaFile.name;

    ft.upload(path,
        "http://my.domain.com/upload.php",
        function(result) {
            console.log('Upload success: ' + result.responseCode);
            console.log(result.bytesSent + ' bytes sent');
        },
        function(error) {
            console.log('Error uploading file ' + path + ': ' + error.code);
        },
        { fileName: name });
}

    <button onclick="captureAudio();">Capture Audio</button> <br>

Answer 1

This is not an exactly answer to your problem, but a working alternative. 这不是您问题的确切答案，而是一种可行的替代方案。

Instead of using org.apache.cordova.media-capture I tried org.apache.cordova.media . 我没有使用org.apache.cordova.media-capture，而是尝试了org.apache.cordova.media 。

Here is a small example: 这是一个小例子：

function recordAudio() {
    var src = "myrecording.amr";
    var mediaRec = new Media(src,
        // success callback
        function() {
            console.log("recordAudio():Audio Success");
        },

        // error callback
        function(err) {
            console.log("recordAudio():Audio Error: "+ err.code);
        });

    // Record audio
    mediaRec.startRecord();

    // Stop recording after 10 seconds
    setTimeout(function() {
        mediaRec.stopRecord();
    }, 10000);
}

Unfortunaly each device uses their own audio codec and in case of Android it is the AMR Codec. 不幸的是，每个设备都使用自己的音频编解码器，而在Android的情况下，它是AMR编解码器。 I was able to listen to the record using MPC (Windows) . 我能够使用MPC（Windows）收听记录。 But if you want to upload the file and share it with other users, you'll have to convert it . 但是，如果您要上传文件并与其他用户共享，则必须进行转换。

If you do not find the myrecording.amr file: It is located on devices' root. 如果找不到myrecording.amr文件：它位于设备的根目录下。 I did not figure out how to store files temporary in the application cache folder itself, which is existing. 我没有弄清楚如何在应用程序缓存文件夹本身临时存储文件，这是现有的。

A 10 second recording has < 20kb size. 10秒的录音大小<20kb。

AMR 8000Hz mono 12kbps [Audio]

Which is very bad quality. 这是非常糟糕的质量。 Unfortunaly there seems to be no possibility to increase the quality. 不幸的是，似乎没有可能提高质量。

Answer 2

The problem may be that there's no application that is handling the RECORD_SOUND intent. 问题可能是没有应用程序正在处理RECORD_SOUND意图。

I used this one: 我用过这个：

https://play.google.com/store/apps/details?id=com.brightattic.soundrecorder&hl=en https://play.google.com/store/apps/details?id=com.brightattic.soundrecorder&hl=en

(I have no endorsement for it other than it worked in my test) （除了在我的测试中工作之外，我没有认可它）
