使用phonegap cordova将文件上传到服务器的问题

我有一个非常简单的应用程序，从相机和库上传图片 . 我设法让它按预期工作，由于某种原因我不知道它停止工作 . 我甚至从提交中下载了文件，我确信它正在工作，它不再存在了 .

该应用程序让你拍照，从库中选择一个，然后添加一个小缩略图（这是工作）拍摄/选择的图片，让你提交一个表格 . 上传发生在您选择文件后，表单提交会发送一封电子邮件，其中包含这些文件作为附件（在服务器上完成） .

上传功能始终返回“发生错误：代码= 1”

编辑：我正在通过将我的设备连接到phonegap Windows服务器来测试应用程序 .

EDIT2: apparently the problem was the phonegap emulator, tried on a real apk installation and it worked.
