我正在使用Phonegap创建一个Android应用程序

我已经使用他们网站上的命令安装了phonegap

现在,当我从他们的网站上运行示例相机脚本以使其工作时,我开始使用它

每次我运行下面的代码(即使我将文件链接到phonegap.js),它都会不断抛出错误。我的意思是,脚本运行到HTML并显示按钮,但是当单击按钮时,什么也没有发生,并且在日志中显示:无法读取未定义的属性“DATA_URL”

仍然没有运气的功能。我怀疑这与cordova插件和phonegap有关,因为脚本中只包含phonegap.js。我还阅读了config.xml中的设置,这是我在文档后面通过命令行完成的(除非我做得不对)

我已通过CL构建了应用程序:

phonegap build android
下面添加了cordova-2.5.0.js和destinationType.FILE_URI的代码已成功启用getPhoto()函数,并允许我在库/相册中显示照片

它们似乎都不起作用。

更新 只是我最近也遇到了同样的问题。 如果你添加了摄像头插件和所有需要的权限,主要是你完成了所有的步骤。我认为您的解决方案可以转到您的项目文件夹并执行
phonegap构建
phonegap构建应用程序平台
。 首先保存您的项目数据,使命令行重置项目的结构并删除您添加的文件

让我知道这是否也适用于你,祝你好运。

这是一个Javascript错误。您正在尝试访问未定义变量的属性。此行(在
capturePhoto
capturePhotoEdit
方法中):

应该是:

Camera.DestinationType.DATA_URL

还有一件事:使用Cordova时,最好手头有文档,每次使用新插件或升级到新版本时都可以查看文档(它们往往会频繁更改API,因此Google中的示例通常显示遗留代码)。这是一个Javascript错误。

在我暂停执行时,摄影机有getPicture()方法,但没有DestinationType和PictureSourceType属性

$scope.tomarFoto = function(){
$ionicPlatform.ready(function() {
  var options = {
    quality: 50,
    destinationType: Camera.DestinationType.DATA_URL,
    sourceType: Camera.PictureSourceType.CAMERA

  $cordovaCamera.getPicture(options).then(function (imageData) {
    $scope.cameraimage = "data:image/jpeg;base64," + imageData;
  }, function (err) {
    console.log('Failed because: ' + message);

我没有对Cordova per say做任何事情,但我通过终端安装了Phonegap,创建了一个项目,然后将摄像头脚本实现到一个名为camera.html的文件中。我按原样添加了JS脚本并运行了脚本。日志中不断出现这四个函数的错误。我运行了“phonegap build android”并成功构建了软件包,但在访问摄像头时仍然没有成功。然后它只是一个不同的问题,引发了相同的错误。我已经让库和相册功能正常工作,但摄像头仍然无法工作。最后一次尝试:找到
camera.js
并像
phonegap.js
一样导入到您的html中。我没有对Cordova进行任何操作,但我通过终端安装了phonegap,创建了一个项目,然后将摄像头脚本实现到一个名为camera.html的文件中。我按原样添加了JS脚本并运行了脚本。日志中不断出现这四个函数的错误。我运行了“phonegap build android”并成功构建了软件包,但在访问摄像头时仍然没有成功。然后它只是一个不同的问题,引发了相同的错误。我已经让库和相册功能正常工作,但摄像头仍然无法工作。请在最后一次机会尝试:查找

我应该包括cordova.js还是phonegap.js?自从我使用phonegap命令创建应用程序以来,它没有自动将cordova.js包含在我的项目目录中。我以前使用模板示例项目创建项目,因此我不熟悉新的CLI命令。但是由于cordova.js是特定于平台的,并且
create
命令没有将平台作为参数,我想稍后会在
build
命令中添加它。所以我不需要手动添加它?它将通过build.xml处理?我已经手动将cordova的插件行添加到我的config.xml文件中,我是否需要在构建文件中添加任何内容。杜德,我复制了粘贴了你的“Camera.DestinationType.DATA_URL”,但最后应该是和“I”。根据phonegap和cordova的文档,可能的值是DATA_URL,文件URI和本机URI。我应该包括cordova.js还是phonegap.js?自从我使用phonegap命令创建应用程序以来,它没有自动将cordova.js包含在我的项目目录中。我以前使用模板示例项目创建项目,因此我不熟悉新的CLI命令。但是因为cordova.js是平台规范
