Saving an image from device on remote server

Hi everybody. I'm trying to create an android application that on one of its activities the user can save an image on a remote server. On my server I have a folder name ibuy. Inside it I have a folder name files with a php file that suppose to handle the saving of the images on the server. Inside it I have another folder name files.
This is my php file:

<?php

    $file_path = "ibuy.pixub.com/ibuy/files/";

    $file_path = $file_path . basename( $_FILES['uploaded_file']['name']);
    if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $file_path)) {
        echo "success";
    } else{
        echo "fail";
    }
?>

(The parameter $file_path begins with "h t t p: //")

This is the code inside the activity that is activated after the button is pressed:

final File file = new File(path);
        new Thread(new Runnable() {
            public void run() {
                runOnUiThread(new Runnable() {
                    public void run() {
                    }
                });
                uploadFile();
            }
        }).start();

The property "path" is a correct path to an image on the device.
This is the uploadFile function:

public int uploadFile() {
    final String upLoadServerUri = "ibuy.pixub.com/ibuy/files/UploadToServer.php";
    HttpURLConnection conn;
    DataOutputStream dos;
    String lineEnd = "\r\n";
    String twoHyphens = "--";
    String boundary = "*****";
    int bytesRead, bytesAvailable, bufferSize;
    byte[] buffer;
    int maxBufferSize = 1 * 1024 * 1024;
    File sourceFile = new File(path);
    int serverResponseCode = 0;

    if (!sourceFile.isFile()) {
        Log.e("uploadFile", "Source File not exist : " + path);

        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();
            conn.setDoInput(true); // Allow Inputs
            conn.setDoOutput(true); // Allow Outputs
            conn.setUseCaches(false); // Don't use a Cached Copy
            conn.setRequestMethod("POST");
            conn.setRequestProperty("Connection", "Keep-Alive");
            conn.setRequestProperty("ENCTYPE", "multipart/form-data");
            conn.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary);
            conn.setRequestProperty("uploaded_file", path);

            dos = new DataOutputStream(conn.getOutputStream());

            dos.writeBytes(twoHyphens + boundary + lineEnd);
            dos.writeBytes("Content-Disposition: form-data; name=" + path + ";filename=\"" + path + "\"" + lineEnd);
            dos.writeBytes(lineEnd);

            // create a buffer of  maximum size
            bytesAvailable = fileInputStream.available();

            bufferSize = Math.min(bytesAvailable, maxBufferSize);
            buffer = new byte[bufferSize];

            // read file and write it into form...
            bytesRead = fileInputStream.read(buffer, 0, bufferSize);

            while (bytesRead > 0) {

                dos.write(buffer, 0, bufferSize);
                bytesAvailable = fileInputStream.available();
                bufferSize = Math.min(bytesAvailable, maxBufferSize);
                bytesRead = fileInputStream.read(buffer, 0, bufferSize);

            }

            // send multipart form data necesssary after file data...
            dos.writeBytes(lineEnd);
            dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);

            // Responses from the server (code and message)
            serverResponseCode = conn.getResponseCode();
            String serverResponseMessage = conn.getResponseMessage();

            Log.i("uploadFile", "HTTP Response is : " + serverResponseMessage + ": " + serverResponseCode);

            if (serverResponseCode == 200) {

                runOnUiThread(new Runnable() {
                    public void run() {
                        Log.i("uploadFile", "Path is : " + path);
                    }
                });
            }

            //close the streams //
            fileInputStream.close();
            dos.flush();
            dos.close();

        } catch (MalformedURLException ex) {

            ex.printStackTrace();

            Log.e("Upload file to server", "error: " + ex.getMessage(), ex);
        } catch (Exception e) {

            e.printStackTrace();

            Log.e("Upload file to server Exception", "Exception : " + e.getMessage(), e);
        }
        return serverResponseCode;

    }
}

(The parameter upLoadServerUri begins with "h t t p: //")

I copied almost everything from another user guide. It seems that the code works, I get the correct results. Can anybody give me a hand here, maybe tell me where I had a mistake? Thank you in advance!

Everything is working fine but I can't see the images on the server, as if they didn't got there.

I copied the code and placed it straight under the On the android studio log I see nothing and if I insert "ibuy.pixub.com/ibuy/files/UploadToServer.php" straight into the browser I receive this:
array(0) {
}
fail

How do I do that? What to change in my php file or my java file?

I tried looking for answers as you suggested and found nothing. Can you please post your sample code? Thanks

I copied your code and this is the result i got:

The site won't let me upload the text because it contains links so I got a screen shot of it:

I have absolutely no idea what to do now

Thank you for all your help!

I changed the java code from:

dos.writeBytes("Content-Disposition: form-data; name=" + path + ";filename=\"" + path + "\"" + lineEnd);

to:

dos.writeBytes("Content-Disposition: form-data; name=\\\"uploaded_file\\\";filename=\"" + path + "\"" + lineEnd);

and still it doesn't work.
Now the message I get is this:

Do you have any other suggestion? Thanks

Still nothing
I changed it to:

dos.writeBytes("Content-Disposition: form-data; name=\\uploaded_file\\;filename=\"" + path + "\"" + lineEnd);

and it still didn't save the image.
The result is:

I'm beginning to become desperate

I copied your code and still nothing.

This is the message I get now:

Maybe I should replace the "path" in

dos.writeBytes("Content-Disposition: form-data; name=\"uploaded_file\";filename=\"" + path + "\"" + lineEnd);

with the "uploaded_file"?

What do you think?

It works! Thanks man. You Rock!!!!
