Android - отправить изображение на сервер - Async Task Произошла ошибка во время выполнения doInBackground()

Я хочу сделать приложение, которое делает снимок и отправляет его на онлайн-сервер. Я прочитал много учебников и статей, и это мой код до сих пор:Android - отправить изображение на сервер - Async Task Произошла ошибка во время выполнения doInBackground()

$server_ip = gethostbyname(gethostname());

if (isset($_FILES['image']['name'])) { 
    $target_path = $target_path . basename($_FILES['image']['name']); 


    $response['file_name'] = basename($_FILES['image']['name']); 
    $response['email'] = $email; 

    try { 
     // Throws exception incase file is not being moved 
     if (!move_uploaded_file($_FILES['image']['tmp_name'], $target_path)) { 
      // make error flag true 
      $response['error'] = true; 
      $response['message'] = 'Could not move the file!'; 
     } 

     // File successfully uploaded 
     $response['message'] = 'File uploaded successfully!'; 
     $response['error'] = false; 
     $response['file_path'] = $file_upload_url . basename($_FILES['image']['name']); 
    } catch (Exception $e) { 
     // Exception occurred. Make error flag true 
     $response['error'] = true; 
     $response['message'] = $e->getMessage(); 
    } 
} else { 
    // File parameter is missing 
    $response['error'] = true; 
    $response['message'] = 'Not received any file!F'; 
} 

// Echo final json response to client 
echo json_encode($response); 
?>

Проблема что он падает, когда попадает на эту линию, и я понятия не имею, почему.

response = httpclient.execute(httppost);

Любые идеи/советы, что может быть проблема?

Если у вас есть разрешение, вы можете разместить свой файл манифеста, пожалуйста. –

ответ

Как StackTrace сказал:

Caused by: java.lang.SecurityException: Permission denied (missing INTERNET permission?)

Вы должны добавить internet permission внутри манифеста файла.

<uses-permission android:name="android.permission.INTERNET" />

Другая проблема заключается в:

Caused by: libcore.io.GaiException: getaddrinfo failed: EAI_NODATA (No address associated with hostname)

Возможно, вам нужно проверить имя хоста, которое вы используете для отправки запроса. (http://xxxx/photo.php)

Я уже добавил. Это не проблема. – Diana

@Edward, то вы добавили его неправильно. –

Ошибка конкретно говорит вам, что вам не хватает разрешения и слишком интернет.

Добавить разрешение INTERNET на ваш файл манифеста.

Вы должны добавить следующую строку:

<uses-permission android:name="android.permission.INTERNET" />

Еще одна проблема может быть, что вы можете добавлять разрешение неправильно или если это не так, то вам нужно проверить THIS ANSWER

Проверьте свой адрес хоста или Вы также можете попробовать, добавив это разрешение ниже интернета:

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
