Android 应用程序无法通过php mysql从服务器发送和检索文件

我在我的应用程序中有一个页面，上面有类似的代码和不同的值，它们可以将信息发送到我的PHP MySQL。另一方面，我的应用程序中的此页面无法发送文件并向我发送错误消息：

 E/Volley: [258] BasicNetwork.performRequest: Unexpected response code 406 
 for http://applybpojobs.com/widevalueappfiles/server/api/addvehicle.php

我已经在网站上尝试了许多解决方案，但都没有成功。有人能帮我弄清楚吗

这是我的java：

public class Addvehicle extends AppCompatActivity {

我很难确定哪里出了问题。虽然我看到logcat将我指向php文件，但它并没有明确告诉我要更改什么。该页面几天前还在运行。
