在android应用程序上传文件到FTP服务器

-1

我尝试了几种上传FTP服务器上的文件的方法，但是我失败了。在android应用程序上传文件到FTP服务器

在这里我粘贴我的服务器代码（php）以接受来自设备的文件，请提供与该服务器代码对应的android代码。

<?php 
error_reporting(0); 
include("dbconfig.php");

$status = 1; 
$overwrite = 1; 
/*echo "<pre>"; 
print_r($_POST); 
echo "</pre>";*/ 

/*echo "<pre>"; 
print_r($_FILES); 
echo "</pre>";*/ 
if(trim($_POST['userid'])!='') 
{ 
    $userid = trim($_POST['userid']); 
    $overwrite = trim($_POST['overwrite']); 
    if($overwrite == 0) 
    { 
     $selfilesqry = mysql_query("SELECT filepath FROM userfiles WHERE userid = 1 AND status=1"); 
     while($row = mysql_fetch_array($selfilesqry)) 
     { 
      $selfiles[] = $row['filepath']; 
     } 

    }

    print_r($selfiles);
