Загрузка файла Android – $ _FILES возвращается пустым

Я пытаюсь загрузить изображение из Android-приложения на сервер с PHP-скриптом. HTTP-ответ возвращает STATUS OK: 200, но $ _FILES ["upfile"] ["name"] возвращается пустым. Я проверял права доступа к папкам, а isady – 777.

Мой класс .java

• Загрузка изображения с сервера android на PHP
• отправлять данные на localhost в приложении для Android
• Ошибка 245 в mysql
• Переписать PHP Rijndael алгоритм на Java (Android)
• Чтение результатов запроса HTTP в Android

и вот мой php-файл

 // Where the file is going to be placed $target_path = "uploads/"; /* Add the original filename to our target path. Result is "/uploads/filename.extension" */ $target_path = $target_path . basename( $_FILES['upfile']['name']); if( $_FILES['upfile'] ) { if(move_uploaded_file($_FILES['upfile']['tmp_name'], $target_path)) { // $qry = "UPDATE users set image=".$target_path." where username='$username'"; // $db->query($qry); echo "O arquivo ". basename( $_FILES['upfile']['name']). " está sendo enviado"; } else{ echo "Ocorreu um erro ao realizar envio de arquivo, por favor tente novamente!\n"; echo "Nome do arquivo: " . basename( $_FILES['upfile']['name'])."\n"; echo "target_path: " .$target_path; } }else { echo "Nenhum arquivo careregado!"; /*** ever enters here!!! ***/ } 

Вы можете мне помочь?

благодаря !!!
