我正在尝试在新的BlackBerry 10 Device（Z10）中运行一个phonegap应用程序而且我遇到了一个问题。基本上，我拍了一张照片，我想用FileTransfer将它上传到我的服务器，但FileTransfer失败并带有FileTransferError.FILE_NOT_FOUND_ERR。
然后我尝试使用window.resolveLocalFileSystemURI方法，现在我得到一个FileError.NOT_FOUND_ERR。我假设这两个错误是相关的。
我传递给这两个文件的fileURI是我从navigator.camera.getPicture成功回调中获取的fileURI，看起来像是：
file:///accounts/1000/shared/camera/IMG_00000037.jpg
我从phonegap 2.5.0下载中采用了示例blackberry app并稍微修改了index.html以重现该问题，我将在下面进行介绍：

每当我运行应用程序并尝试拍照时，我都会：

为什么FileTransfer或window.resolveLocalFileSystemURI都找不到从navigator.camera.getPicture返回的文件？我有来自phonegap示例的标准config.xml以及所有必需的功能和权限（至少据我所知）
下面是我的config.xml：

重现我的问题的步骤：
答案 0 :(得分：2)
您需要同时执行blackberry.io.sandbox = false;并删除file：//协议，至少根据我从文件系统访问文件的经验。此外，您不应该直接访问共享路径。使用blackberry.io.sharedFolder属性，如本页示例所示：https://developer.blackberry.com/html5/apis/blackberry.io.html
您的文件系统路径应为blackberry.io.sharedFolder +'camera / IMG_00000037.jpg'
BB10的安全沙箱设计意味着每个应用程序都有自己的共享文件系统区域的文件路径。
答案 1 :(得分：1)
听起来很像我在这里看到的问题：https://github.com/blackberry/BB10-WebWorks-Framework/issues/536
尝试删除 file：// 协议以获取： /accounts/1000/shared/camera/IMG_00000037.jpg
答案 2 :(得分：0)
您可以尝试添加<access uri="file://accounts/" subdomains="ture"/>代替'store / home'。
编辑：此外，在处理文件系统时，您需要将沙盒模式设置为false，否则您可能无权访问该文件。
blackberry.io.sandbox = false;
除此之外，看起来你几乎所有设置都很好。

基于2013年4月2日的chadtatro回答：
请添加config.xml
<access uri="file:///accounts/1000/removable/sdcard/" subdomains="true"/>
我也加入了我的项目：
webworks plugin add com.blackberry.io
答案 5 :(得分：0)
几天后我遇到了同样的问题。让图像停止工作，我的代码中没有任何内容。
注意cordova-plugin-file，因为在其3.0.1-dev版本（也许是其他版本）中，您开发的应用并不会要求获取访问文件的权限，以及从相机获取图片或画廊会失败。
我使用此插件的2.1.0版本解决了它：
cordova plugin add https://git-wip-us.apache.org/repos/asf/cordova-plugin-file.git#r2.1.0
