我正在尝试在新的 BlackBerry 10 设备 (Z10) 中运行 phonegap 应用程序，但遇到了问题。基本上，我拍了一张照片，我想通过 FileTransfer 将它上传到我的服务器，但是 FileTransfer 失败并出现 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。
我传递给这两个的 fileURI 是我从 navigator.camera.getPicture 成功回调中返回的 fileURI，看起来像：
file:///accounts/1000/shared/camera/IMG_00000037.jpg
我从 phonegap 2.5.0 下载中获取了示例 blackberry 应用程序，并稍微修改了 index.html 以重现该问题，我将包括以下内容：

每当我运行应用程序并尝试拍照时，我都会得到：
Unable to resolve local file system URI...
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 具有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：
- 遵循本指南（使用 BlackBerry 10(QNX) 步骤）
- 用我提供的文件替换给定的 index.html 文件
- 用我提供的文件替换给定的 config.xml 文件（更改应该是最小的）
- 在 BB10 设备上调试它（我使用的是 Z10）
- 单击“捕获照片”按钮，如果您连接了远程 Web 检查器，您应该会看到错误
