在android中向web服务发送xml文件
朋友们好，我正在尝试通过android应用程序发送存储在sd卡中的xml文件，代码如下：在android中向web服务发送xml文件,android,xml,file,http-post,Android,Xml,File,Http Post,朋友们好，我正在尝试通过android应用程序发送存储在sd卡中的xml文件，代码如下： public class CartDetailsActivity extends Activity { File newxmlfile = new File(Environment.getExternalStorageDirectory() + "/"+GlobalVariables.ada_login+".xml"); @Override protected void o

我不知道这段代码有什么问题，因为它不工作，文件也没有上传。任何帮助都将不胜感激 您可以将其添加为

// you can add an if statement here and do other actions based on the response

and php code.
<?php

和php代码。
从尝试下面的代码，希望这对您有所帮助 PHP web服务
