我正在尝试使用 Android 中的 Phone gap 运行 Camera API，并且遇到了各种问题。

我刚刚复制了 phonegap 相机示例。

我收到以下错误

07-12 18:18:00.706: E/Web Console(17837): Uncaught TypeError: Cannot read property 'SAVEDPHOTOALBUM' of undefined at file:///android_asset/www/index.html:98

07-12 18:17:59.456: E/Web Console(17837): Uncaught ReferenceError: Camera is not defined at file:///android_asset/www/index.html:67

我尝试了所有其他目的地类型。它很有效

destinationType: destinationType.FILE_URI
destinationType: Camera.DestinationType.FILE_URI
destinationType: destinationType.DATA_URL

我还添加了相机权限和硬件相机权限。但还是失败了

确保在 HTML中包含正确的（最新的）cordova文件。

我有同样的问题，我包括

cordova-1.8.0.js

而不是

cordova-2.4.0.js

您可以尝试使用 phonegap 拍摄照片

<script type="text/javascript" charset="utf-8" src="cordova-2.5.0.js"></script>
<script type="text/javascript" charset="utf-8">

var pictureSource;   // picture source
var destinationType; // sets the format of returned value 

// Wait for Cordova to connect with the device
//
document.addEventListener("deviceready",onDeviceReady,false);

// Cordova is ready to be used!
//
function onDeviceReady() {
    pictureSource=navigator.camera.PictureSourceType;
    destinationType=navigator.camera.DestinationType;
}

// Called when a photo is successfully retrieved
//
function onPhotoDataSuccess(imageData) {
    // Uncomment to view the base64 encoded image data
    //alert(imageData);  

    // Get image handle
    //
    var smallImage = document.getElementById('smallImage');
    // Unhide image elements
    //
    smallImage.style.display = 'block';

    // Show the captured photo
    // The inline CSS rules are used to resize the image
    //
    smallImage.src = "data:image/jpeg;base64," + imageData;
}

// Called when a photo is successfully retrieved
//
function onPhotoURISuccess(imageURI) {
    alert("inside large image")
    // Uncomment to view the image file URI 
    // console.log(imageURI);

   // Get image handle
   //
    var largeImage = document.getElementById('largeImage');

  // Unhide image elements
  //
    largeImage.style.display = 'block';

  // Show the captured photo
  // The inline CSS rules are used to resize the image
  //
    largeImage.src = imageURI;
}

// A button will call this function
//
function capturePhoto() {
  // Take picture using device camera and retrieve image as base64-encoded string
    navigator.camera.getPicture(onPhotoDataSuccess, onFail, { quality: 50,
    destinationType: destinationType.DATA_URL });
}

// A button will call this function
//
function capturePhotoEdit() {
  // Take picture using device camera, allow edit, and retrieve image as base64-encoded string  
    navigator.camera.getPicture(onPhotoDataSuccess, onFail,
    { quality: 20, allowEdit: true,
    destinationType: destinationType.DATA_URL });
}

// A button will call this function
//
function getPhoto(source) {
  // Retrieve image file location from specified source
    navigator.camera.getPicture(onPhotoURISuccess, onFail, { quality: 50, 
    destinationType: destinationType.FILE_URI,
    sourceType: source });
}


// Called if something bad happens.
// 
function onFail(message) {
    alert('Failed because: ' + message);
}

我遇到了同样的问题，我通过三个步骤解决了它

javascript包括

我只使用了 cordova.js 并删除了所有 phonegap.js

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

安装插件

您必须使用命令行安装相机插件；只有xml不起作用

cordova plugin add org.apache.cordova.camera

使用正确的 android-package

在您的 xml 中，您可能使用org.apache.cordova.CameraLauncher它是错误的，并且会给您 NullPointer 异常。可以像这样包含正确的包

<feature name="Camera">
    <param name="ios-package" value="CDVCamera" />
    <param name="android-package" value="org.apache.cordova.camera.CameraLauncher" />
</feature>

试试看！谢谢 ：）

我有同样的问题。

您正在使用pictureSource.PHOTOLIBRARY和pictureSource.SAVEDPHOTOALBUM直接在代码中。

问题是 html 在 javascript 之前加载，然后您尝试访问pictureSource. 但还没有具体说明。

当应用程序完全加载时，您必须使用它（例如，在documents.ready中使用jQuery事件或在javascript中使用一些替代方法）

2.0.0.js 这可能会解决你的问题

你的代码是正确的，只检查这些cordova-2.0.0.js 文件

只需添加
<script src="phonegap.js"></script>
我的 html 就为我解决了！
而且我也有<script src="cordova.js"></script>，所以删除它并只保留
<script src="phonegap.js"></script>。
