The log message is clear, you are trying to upload a directory, not a file :

String existingFileName = Environment.getExternalStorageDirectory()
                .getPath() + "/AudioRecorder/"

/AudioRecorder/ is not an audio file.You should perhaps append the audio filename at the end.

If you have to upload all the files in the dir, then think about doing that inside an (Intent)service.

  1. Add the filename as parameter to your method :

  2. In your activity, Loop into the files list, and for each file :

    for(String filename : filesList ){

                Intent intent = new Intent(this, UploadIntentService.class);
                Bundle params = new Bundle();
                params.putString(UploadIntentService.KEY_FILE_NAME, filename);
                activity.startService(intent);
}

  3. The Service :

    public class UploadIntentService extends IntentService {

public static final String KEY_FILE_NAME= "filename";
public UploadIntentService() {
    super("UploadIntentService");
            }

@Override
protected void onHandleIntent(Intent intent) { 
String filename = intent.getBundle().getStringExtra(UploadIntentService.KEY_FILE_NAME);      

doAudioFileUpload(filename);
       }

   private void doAudioFileUpload(String filename) {
    HttpURLConnection conn = null;
    DataOutputStream dos = null;
    DataInputStream inStream = null;
    String existingFileName = Environment.getExternalStorageDirectory()
            .getPath() + "/AudioRecorder/"+filename;

    System.out.println("Inside of doupload nd path is === "
            + existingFileName);

    String lineEnd = "\r\n";
    String twoHyphens = "--";
    String boundary = "*****";
    int bytesRead, bytesAvailable, bufferSize;
    byte[] buffer;
    int maxBufferSize = 1 * 1024 * 1024 * 1024;
    String urlString = "http://link to server/folder-name/upload_audio.php";
    try {
        // ------------------ CLIENT REQUEST
        FileInputStream fileInputStream = new FileInputStream(new File(
                existingFileName));
        // open a URL connection to the Servlet
        URL url = new URL(urlString);
        // Open a HTTP connection to the URL
        conn = (HttpURLConnection) url.openConnection();
        // Allow Inputs
        conn.setDoInput(true);
        // Allow Outputs
        conn.setDoOutput(true);
        // Don't use a cached copy.
        conn.setUseCaches(false);
        // Use a post method.
        conn.setRequestMethod("POST");
        conn.setRequestProperty("Connection", "Keep-Alive");
        conn.setRequestProperty("Content-Type",
                "multipart/form-data;boundary=" + boundary);
        dos = new DataOutputStream(conn.getOutputStream());
        dos.writeBytes(twoHyphens + boundary + lineEnd);
        dos.writeBytes("Content-Disposition: form-data; name=\"uploadedfile\";filename=\""
                + existingFileName + "\"" + 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);
        // close streams
        Log.e("Debug", "File is written");
        fileInputStream.close();
        dos.flush();
        dos.close();
    } catch (MalformedURLException ex) {
        Log.e("Debug", "error: " + ex.getMessage(), ex);
    } catch (IOException ioe) {
        Log.e("Debug", "error: " + ioe.getMessage(), ioe);
    }
    // ------------------ read the SERVER RESPONSE
    try {
        inStream = new DataInputStream(conn.getInputStream());
        String str;

        while ((str = inStream.readLine()) != null) {
            Log.e("Debug", "Server Response " + str);
        }
        inStream.close();

    } catch (IOException ioex) {
        Log.e("Debug", "error: " + ioex.getMessage(), ioex);
    }
}

    Hope it helps
