Android将任何文件上传到服务器
我是android新手，我没有得到任何好的教程来上传任何文件到服务器。请为我提供一个很好的教程上传任何文件到服务器。文件大小应该是任意的，并且还需要一个跟踪上传百分比的进度对话框。我需要简单而好的文件上传教程，但不仅仅是图像或视频。下面是一个示例类，它将文件上传到服务器，并在上传文件时显示进度对话框Android将任何文件上传到服务器,android,web-services,file-upload,Android,Web Services,File Upload,我是android新手，我没有得到任何好的教程来上传任何文件到服务器。请为我提供一个很好的教程上传任何文件到服务器。文件大小应该是任意的，并且还需要一个跟踪上传百分比的进度对话框。我需要简单而好的文件上传教程，但不仅仅是图像或视频。下面是一个示例类，它将文件上传到服务器，并在上传文件时显示进度对话框 public class UploadToServer extends Activity { TextView messageText; Button uploadButton; int serv

以获取拾取图像的路径并将其上载到服务器
@Override
protected void onActivityResult(int reqCode, int resCode, Intent data) {
if(resCode == Activity.RESULT_OK && data != null) {
// get file path of picked image and call upoadFile(uploadFilePath) method to upload it
}
}
在此处签出完整的源代码如果您想使用服务器发送或接收数据，最好的方法之一是使用改装库。
使用它非常简单，您可以使用它的文档表单。
我希望它能为您工作。但它会上载我想从SD卡中选择的预定义文件，并以相同的扩展名上载到服务器检查我的更新答案以从SD卡中选择文件，并获取将其上载到服务器的路径
