Android to Php server communicaton using HttpURLConnection

Question

My project is to upload the image, audio files with some parameter(like description and date).

Though Google announced to use HttpURLConnection instead of httpclient. I am using HttpURLConnection.

I have an code which upload the image and audio in server folder.

But the description which I send is not received in the server.

Like this question many in Stackover flow. But I did not get exact solution.

My android code is:

                FileInputStream fileInputStream = new FileInputStream(sourceFile_image);
                URL url = new URL(upLoadServerUri);
                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", fileName);

                dos = new DataOutputStream(conn.getOutputStream());
                dos.writeBytes(twoHyphens + boundary + lineEnd);

                //adding parameter 

                String description = ""+"Desceiption about the image";

                // Send parameter #name
                dos.writeBytes("Content-Disposition: form-data; name=\"description\"" + lineEnd);
                dos.writeBytes("Content-Type: text/plain; charset=UTF-8" + lineEnd);
                dos.writeBytes("Content-Length: " + description.length() + lineEnd);
                dos.writeBytes(lineEnd);
                dos.writeBytes(description + lineEnd);
                dos.writeBytes(twoHyphens + boundary + lineEnd);

                // Send #image

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

And Php Code:

$description= $_POST['description'];

   $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";
   }

Image and audio updating successfully.

But parameter not received or I dont know how to receive the parameter in php.

Is my android and php code to send and receive parameter is correct?

Is Any other solution.

I am trying lot but not works and not getting idea too.

Answer 1

// Send parameter #name
dos.writeBytes("Content-Disposition: form-data; name=\"name\"" + lineEnd);

That should be:

// Send parameter #description
dos.writeBytes("Content-Disposition: form-data; name=\"description\"" + lineEnd);

Answer 2

check this link

Android code:

String description = ""+"Desceiption about the image";


            dos.writeBytes("Content-Disposition: form-data; name=\"description\"" + lineEnd); 
            //dos.writeBytes("Content-Type: text/plain; charset=UTF-8" + lineEnd);
            //dos.writeBytes("Content-Length: " + description.length() + lineEnd);
            dos.writeBytes(lineEnd);
            dos.writeBytes(description); // mobile_no is String variable
            dos.writeBytes(lineEnd);

Php code:

$description =$_POST['description'];
