Estoy cargando video y foto. Y está funcionando bien. Ahora quiero mostrar la barra de progreso mientras cargo datos con porcentaje. Tomé referencia de Android Hive y se implementó enhttpclient y lo modifiqué en consecuenciahttpurlconnectionCualquier ayuda será apreciada. Gracias.

Esta es mi actividad principal donde se realiza la tarea asincrónica.

protected void onProgressUpdate(Integer... progress) {
        // Making progress bar visible
        progressBar.setVisibility(View.VISIBLE);

        // updating progress bar value
        progressBar.setProgress(progress[0]);

        // updating percentage value
        txtPercentage.setText(String.valueOf(progress[0]) + "%");
    }

    @Override
    protected String doInBackground(Void... params) {
        return uploadFile();
    }

    @SuppressWarnings("deprecation")
    private String uploadFile() {
        String responseString = null;
            String charset = "UTF-8";
            String requestURL = "YOUR_URL";

            VideoUpload multipart = null;
            try {
                multipart = new VideoUpload(Config.FILE_UPLOAD_URL, charset);
            } catch (IOException e) {
                e.printStackTrace();
            }

        {
            //========================================================
            AndroidMultiPartEntity entity = new AndroidMultiPartEntity(
                    new AndroidMultiPartEntity.ProgressListener() {

                        @Override
                        public void transferred(long num) {
                            publishProgress((int) ((num / (float) totalSize) * 100));
                        }
                    });
            //========================================================
            multipart.addFormField("website", "www.androidhive.info");
            multipart.addFormField("email", "[email protected]");
            try {
                multipart.addFilePart("image", new File(filePath));
            } catch (IOException e) {
    ,            e.printStackTrace();
            }

            try {
                List<String> response = multipart.finish(); // response from server.
            } catch (IOException e) {
                e.printStackTrace();
            }
        }

        return responseString;
    }

    @Override
    protected void onPostExecute(String result) {
        Log.e(TAG, "Response from server: " + result);

        // showing the server response in an alert dialog
        showAlert(result);

        super.onPostExecute(result);
    }

}

Esta es mi clase de carga para httpurlconnections y está funcionando.

aquí tomé la clase de barra de progreso de androidhive pero no sé cómo usarla

public class AndroidMultiPartEntity extends MultipartEntity

 {

private final ProgressListener listener;

public AndroidMultiPartEntity(final ProgressListener listener) {
    super();
    this.listener = listener;

        final ProgressListener listener) {
    super(mode);
    this.listener = listener;
}

public AndroidMultiPartEntity(HttpMultipartMode mode, final String boundary,
        final Charset charset, final ProgressListener listener) {
    super(mode, boundary, charset);
    this.listener = listener;
}

@Override
public void writeTo(final OutputStream outstream) throws IOException {
    super.writeTo(new CountingOutputStream(outstream, this.listener));
}

public static interface ProgressListener {
    void transferred(long num);
}

public static class CountingOutputStream extends FilterOutputStream {

    private final ProgressListener listener;
    private long transferred;

    public CountingOutputStream(final OutputStream out,
            final ProgressListener listener) {
        super(out);
        this.listener = listener;
        this.transferred = 0;
    }

    public void write(byte[] b, int off, int len) throws IOException {
        out.write(b, off, len);
        this.transferred += len;
        this.listener.transferred(this.transferred);
    }
