Senden Sie img an Server

Question

Ich versuche, Bild (nach der Erfassung) an den Server über Mobiltelefon (Android) senden Dazu verwende ich PHP-Skript (es auf Server hochgeladen) Und JAVA-Code, um Bild zu posten.

Die URL des PHP-Skript: http://nwstudio.esy.es/AndroidFileUpload/uploads/fileUpload.php

Auf Mobil nach Klick-Taste für den Upload i ohne Text der Fehler oder alles nur kleine leere Fenster zu sehen (es sollte über Upload werden msg)

Was ich tun falsch? ;/

PHP:

<?php 

// Path to move uploaded files 
$target_path = "uploads/"; 

// array for final json respone 
$response = array(); 

// getting server ip address 
$server_ip = gethostbyname(gethostname()); 

// final file url that is being uploaded 
$file_upload_url = 'http://' . $server_ip . '/' . 'AndroidFileUpload' . '/' . $target_path; 


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

    // reading other post parameters 
    $email = isset($_POST['email']) ? $_POST['email'] : ''; 
    $website = isset($_POST['website']) ? $_POST['website'] : ''; 

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

    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); 
?>

Answer 1

empfehle ich Ihnen nicht AsyncTask für diesen Zweck zu tun, verwenden. Statt AsyncTask versuchen Bild senden mit Retrofit 2

UPDATE

Das ist mein Projekt Retrofit2Sample die Nutzung von Retrofit zeigt 2. Ich glaube, dass es hilft zu verstehen, wie es funktioniert und zeigen, wie man mit diesem tollen Rest-Client arbeitet.
