Question

HI I need to upload images from SD card to server, the following code i am using in my class, i can't able to send images from my SD card to the server and also i didn't get any response from server whether it is uploading successfully or not. Can anyone help me out ? I have tried many times, i dont know where i am getting problem in my below code. As well please check my below PHP Script which i have given, is it right or wrong.

  public class UploadImage {

    static int serverResponseCode = 0;

    /********** File Path *************/
    final static String uploadFilePath =         Environment.getExternalStorageDirectory().getPath() + "/PMGRMS/";
    static String upLoadServerUri = "api-filepath";

    public static int uploadImage(String fName) {

        String fileName = uploadFilePath + "service_lifecycle.png";

        HttpURLConnection conn = null;
        DataOutputStream dos = null;
        String lineEnd = "\r\n";

        int bytesRead, bytesAvailable, bufferSize;
        byte[] buffer;
        int maxBufferSize = 1 * 1024 * 1024;
        File sourceFile = new File(fileName);

        if (!sourceFile.isFile()) {

            Log.e("UploadImage: ", "Image not found on SD");

            return 0;

        } else {
            try {

                // open a URL connection to the Servlet
                FileInputStream fileInputStream = new FileInputStream(sourceFile);
                URL url = new URL(upLoadServerUri);

                // Open a HTTP connection to the URL
                conn = (HttpURLConnection) url.openConnection();

here is my php script that i am using..

// PHP Script

     if($id == "android")
{
  // gallery path  
    $file_path = "../Gallery/Android/";
 $file_path = $file_path . basename( $_FILES['PMGRMS']['name']);
   if(move_uploaded_file($_FILES['PMGRMS']['tmp_name'], $file_path)) {
       echo "Image is upload";
   } else{enter code here
       echo "Image is not Upload";
   }
}

Answer 1

in your php code you are checking for the id android but i could not find any conn.setRequestProperty() setting a value to "android" please try adding some property that has a value "android"

if not success please try the below code for uploading your files, i'm using this in my application to upload images to my server.

public String multipartRequest(String urlTo, String post, String filepath, String filefield) throws ParseException, IOException {

        HttpURLConnection connection = null;
        DataOutputStream outputStream = null;
        InputStream inputStream = null;

        String twoHyphens = "--";
        String boundary = "*****" + Long.toString(System.currentTimeMillis()) + "*****";
        String lineEnd = "\r\n";

        String result = "";

        int bytesRead, bytesAvailable, bufferSize;
        byte[] buffer;
        int maxBufferSize = 1 * 1024 * 1024;

        String[] q = filepath.split("/");
        int idx = q.length - 1;

        try {
            File file = new File(filepath);
            FileInputStream fileInputStream = new FileInputStream(file);

            URL url = new URL(urlTo);
            connection = (HttpURLConnection) url.openConnection();

            connection.setDoInput(true);
            connection.setDoOutput(true);
            connection.setUseCaches(false);

            connection.setRequestMethod("POST");
            connection.setRequestProperty("Connection", "Keep-Alive");
            connection.setRequestProperty("User-Agent", "Android Multipart HTTP Client 1.0");
            connection.setRequestProperty("Content-Type", "multipart/form-data; boundary=" + boundary);

            outputStream = new DataOutputStream(connection.getOutputStream());
            outputStream.writeBytes(twoHyphens + boundary + lineEnd);
            outputStream.writeBytes("Content-Disposition: form-data; name=\"" + filefield + "\"; filename=\"" + q[idx] + "\"" + lineEnd);
            outputStream.writeBytes("Content-Type: application/octet-stream" + lineEnd);
            outputStream.writeBytes("Content-Type: image/jpeg" + lineEnd);
            outputStream.writeBytes("Content-Transfer-Encoding: binary" + lineEnd);

            buffer = new byte[bufferSize];
            final double totalSize = bytesAvailable;

            bytesRead = fileInputStream.read(buffer, 0, bufferSize);
            double uploaded = bytesRead;
            while (bytesRead > 0) {
                outputStream.write(buffer, 0, bufferSize);
                bytesAvailable = fileInputStream.available();
                final int percent = (int) (uploaded / totalSize) * 100;
                final double sizeUploaded = uploaded;
                mContext.runOnUiThread(new Runnable() {
                    @Override

                    }
                });
                System.out.println(uploaded / totalSize);
                bufferSize = Math.min(bytesAvailable, maxBufferSize);
                bytesRead = fileInputStream.read(buffer, 0, bufferSize);
                uploaded = uploaded + bytesRead;
                HomeActivity.mNotifyBuilder.setProgress(100, percent, false);
                // Displays the progress bar for the first time.
                HomeActivity.mNotificationManager.notify(HomeActivity.NOTIFICATION_ID, HomeActivity.mNotifyBuilder.build());
            }

            outputStream.writeBytes(lineEnd);

            // Upload POST Data
            String[] posts = post.split("&");
            int max = posts.length;
            for (int i = 0; i < max; i++) {
                outputStream.writeBytes(twoHyphens + boundary + lineEnd);
                String[] kv = posts[i].split("=");
                outputStream.writeBytes("Content-Disposition: form-data; name=\"" + kv[0] + "\"" + lineEnd);

            }

            outputStream.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);

            inputStream = connection.getInputStream();
            result = this.convertStreamToString(inputStream);

            fileInputStream.close();
            inputStream.close();
            outputStream.flush();   
            outputStream.close();

            return result;
        } catch (Exception e) {

            e.printStackTrace();

try this code

public String postData(String post_url,List<NameValuePair> post_parameters_list,String file) throws ClientProtocolException, IOException
{
        int response_code = -1;
        HttpPost httppost = new HttpPost(post_url);
        httppost.setEntity(new UrlEncodedFormEntity(post_parameters_list));
        FileEntity reqEntity = new FileEntity(new File(file),"binary/octet-stream");
        reqEntity.setChunked(true);
        httppost.setEntity(reqEntity);
        HttpResponse response = httpclient.execute(httppost);
        response_code = response.getStatusLine().getStatusCode();
        if (response_code == HttpStatus.SC_UNAUTHORIZED)
        {
            Log.e("HttpResponse", "un authorized");
    //      insertActivityLog("Session timed out. The operation will be retried again");
        }
        else if(response_code == 999 || response_code == HttpStatus.SC_INTERNAL_SERVER_ERROR)
        {
            Log.e("HttpResponse", "Internal Server");
            new Error("Time Out","Internal Server Error. Please contact support.");
        }
        else if(response_code == -1 )
        {
            Log.e("HttpResponse", "Socket connection timeout");
            new Error("Time Out","Response returned from the server is empty. Please contact support.");
        }
        if (response_code == HttpStatus.SC_UNAUTHORIZED)
        {
            // credential check failed
            Log.e("HTTP status", "unauthorised");
            new Error("UNAUTHORIZED","unauthorised for the user " + post_parameters_list.get(0).getName());
        }
        else if (response_code == HttpStatus.SC_FORBIDDEN)
        {
            // forbidden
            Log.e("HTTP status", "Forbidden");
            new Error("Forbidden","User " + post_parameters_list.get(0).getName() + " does not have access to this project");
        }
        return response_code == HttpStatus.SC_OK ? EntityUtils.toString(response.getEntity()) : null;
}

Answer 3

This code is work use java

HttpClient client = new DefaultHttpClient();
HttpPost postMethod = new HttpPost("http://192.195.68.83/Upload/index.php");
File file = new File(fileUri.getPath());
MultipartEntity entity = new MultipartEntity();
FileBody contentFile = new FileBody(file);
entity.addPart("userfile",contentFile);
StringBody contentString = new StringBody("This is contentString");
entity.addPart("contentString",contentString);

postMethod.setEntity(entity);
HttpResponse response = client.execute(postMethod);

and php's code

$uploads_dir = '/Library/WebServer/Documents/Upload/upload/'.$_FILES['userfile']['name'];
if(is_uploaded_file($_FILES['userfile']['tmp_name'])) {
        echo $_POST["contentString"]."\n";
        echo  "File path = ".$uploads_dir;
        move_uploaded_file ($_FILES['userfile'] ['tmp_name'], $uploads_dir);
} else {
        echo "\n Upload Error";
        echo "filename '". $_FILES['userfile']['tmp_name'] . "'.";
        print_r($_FILES);
}
