我正在尝试通过安卓手机将图像上传到我的在线服务器，但出现错误。
错误:
03-04 00:08:51.751: I/uploadFile(28327): HTTP Response is : Internal Server Error: 500
这是我的主课:

}
这是 php :
<?php
$file_path = "uploads/";
$file_path = $file_path . basename( $_FILES['uploaded_file']['name']);
if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $file_path)) {
echo "success";
} else{
echo "fail";
}
?>
