Извините за мой английский. Я много раз пытаюсь включить libruary ZXing для проверки кода qr. Но не удалось. Я загружаю libruary от this, затем добавляю в eclipse и включаю core.jar и проверяю Android libruary. Затем я добавить libruary папки ZXing в моем приложении, но у меня есть эта ошибка:Android ZXing QR scan
