Question

当我使用捕获插件时，它总是在拍照后崩溃应用程序。当我单击“捕获”按钮时，它会打开相机应用程序，我会拍照，然后单击复选标记，然后应用程序关闭并说：“不幸的是，HelloWorld已经停止了。”然后，如果我查看图库应用程序，照片就在那里。有什么我做错了吗？或者插件有什么问题吗？

这就是我的所作所为：

我创建了一个全新的phonegap 3.x（确切地说是3.1.0-0.15.0）项目

phonegap create exampleProject
cd exampleProject

并安装了捕获插件

phonegap local plugin add https://git-wip-us.apache.org/repos/asf/cordova-plugin-media-capture.git

将org.apache.cordova.media-capture放在plugins文件夹中。然后我建立了项目：

phonegap build android

这把org.apache.cordova.file放在plugins文件夹中（因为media-capture依赖于它），在plugins文件夹中创建了android.json。它还创建平台/ android并将正确的js文件放在platforms / android / assets / www / plugins和平台/ android / src中的正确java文件

我在index.html中添加了以下内容：

<input type="button" value="Capture" onClick="capture();" />

这是整个文件：

<!DOCTYPE html>
<html>
    <head>
        <meta charset="utf-8" />
        <meta name="format-detection" content="telephone=no" />
        <meta name="viewport" content="user-scalable=no, initial-scale=1, maximum-scale=1, minimum-scale=1, width=device-width, height=device-height, target-densitydpi=device-dpi" />
        <link rel="stylesheet" type="text/css" href="css/index.css" />
        <title>Hello World</title>
    </head>
    <body>
        <div class="app">
            <h1>PhoneGap</h1>
            <div id="deviceready" class="blink">
                <p class="event listening">Connecting to Device</p>
                <p class="event received">Device is Ready</p>
            </div>
            <input type="button" value="Capture" onClick="capture();" />
        </div>
        <script type="text/javascript" src="phonegap.js"></script>
        <script type="text/javascript" src="js/index.js"></script>
        <script type="text/javascript">
            app.initialize();
        </script>
    </body>
</html>

将capture（）和getErrorMessage（）函数添加到index.js的末尾：

var app = {
    // Application Constructor
    initialize: function() {
        this.bindEvents();
    },
    // Bind Event Listeners
    //
    // Bind any events that are required on startup. Common events are:
    // 'load', 'deviceready', 'offline', and 'online'.
    bindEvents: function() {
        document.addEventListener('deviceready', this.onDeviceReady, false);
    },
    // deviceready Event Handler
    //
    // The scope of 'this' is the event. In order to call the 'receivedEvent'
    // function, we must explicity call 'app.receivedEvent(...);'
    onDeviceReady: function() {
        app.receivedEvent('deviceready');
    },
    // Update DOM on a Received Event
    receivedEvent: function(id) {
        var parentElement = document.getElementById(id);
        var listeningElement = parentElement.querySelector('.listening');
        var receivedElement = parentElement.querySelector('.received');

        listeningElement.setAttribute('style', 'display:none;');
        receivedElement.setAttribute('style', 'display:block;');

        console.log('Received Event: ' + id);
    }
};

function capture() {
    var options = { limit: 1 };
    try {
        navigator.device.capture.captureImage(
            function(response) {
                alert("success: response=" + stringify(response));
            },
            function(CaptureError) {
                alert('Error: ' + getErrorMessage(CaptureError));
            },
            options
        );
    } catch(e) {
        alert("catch e="+e);
    }
}

function getErrorMessage(CaptureError) {
  var errorMessage = 'An unknown error occured while trying to get your media, please try again.';
  switch(CaptureError.code) {
    case CaptureError.CAPTURE_NOT_SUPPORTED:
      errorMessage = 'This app does not support the media type.';
      break;
    case CaptureError.CAPTURE_NO_MEDIA_FILES:
      errorMessage = 'No media files returned.';
      break;
    case CaptureError.CAPTURE_INTERNAL_ERR:
      errorMessage = 'The capture process experienced an internal error.';
      break;
    case CaptureError.CAPTURE_APPLICATION_BUSY:
      errorMessage = 'The application was too busy with something else to handle the media capture.';
      break;
    case CaptureError.CAPTURE_INVALID_ARGUMENT:
      errorMessage = 'Values submitted for capture were out of range, notify support.';
      break;
    case 3:
      errorMessage = 'Did you cancel? Please try again.';
      break;
    default:
      break;
  }
  return errorMessage;
}

然后我构建应用程序：

phonegap build android

在我的Android设备上运行它并体验上述问题

Answer 1

使用logcat（与Android SDK捆绑在一起）查看是否有任何来自phonegap的错误消息。
