Как сохранить изображение через захват в android на php?

Мы пробовали этот код для android и php. См. Ниже код.

• В чем разница между модификаторами доступа в php?
• Как прочитать ответ php-кода на javas-код андроид
• Использование Java для анализа XML
• Несоответствие шифрования между Java и PHP
• Использование javascript и PHP для разработки собственных приложений для Android

Он возвращает синтаксический анализ bytestring. Его значение слишком велико.

PHP

  $base=$Data['images']; $binary=base64_decode($base); header('Content-Type: bitmaps; charset=utf-8'); header("Content-Length: " . mb_strlen($base, '8bit')); $file = fopen('qr_code.jpeg', 'wb'); fwrite($file, $binary); fclose($file); echo 'Image upload complete!!, Please check your php file directory'; 

Над кодом работает. Но у него есть проблема. Сохранение изображения успешно в папке, но изображение будет отображаться как поврежденное. Как мы можем решить эту проблему.

Заранее спасибо.
