How to Show Progress Bar while uploading with percentage

Question

I am uploading video and photo.and its working fine .now i want to show progress bar while uploading data with percentage.i took reference from android hive and its implemented in httpclient and i modified it accordingly httpurlconnection.Any help will appreciated .thank you.

This is my main Activity where async task is performing.

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);
    }

}

this is my uploding class for httpurlconnections and its working .

public VideoUpload(String requestURL, String charset)

    } else {

    return response;
}

here i took progress bar class from androidhive but i don't know how to use it

public class AndroidMultiPartEntity extends MultipartEntity

 {

private final ProgressListener listener;

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

public AndroidMultiPartEntity(final HttpMultipartMode mode,
        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);
    }

    public void write(int b) throws IOException {
        out.write(b);
        this.transferred++;
        this.listener.transferred(this.transferred);
    }
}
}

Answer 1

There is progressUpdate method in AsyncTask class, which will return you progress of file uploading, here is my code which might help you out.

        private final ProgressDialog mDialog;

        mDialog = new ProgressDialog(context);
        mDialog.setMax(100);
        mDialog.setMessage("Uploading " + file.getName());
        mDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
        mDialog.setProgress(0);
        mDialog.setButton("Cancel", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int which) {
                // This will cancel the putFile operation
                mRequest.abort();
            }
        });
        mDialog.show();

    @Override
    protected void onProgressUpdate(Long... progress) {
        int percent = (int)(100.0*(double)progress[0]/mFileLen + 0.5);
        mDialog.setProgress(percent);
    }

Use this code this is perfect works for me for File Upload

    FileUploadListener listener;

    private static final String LINE_FEED = "\r\n";
    private HttpURLConnection httpConn;
    private String charset;
    private OutputStream outputStream;
    private PrintWriter writer;
    public int statusCode;
    public String mURL;

    public interface FileUploadListener {
        void onUpdateProgress(int percentage, long kb);

        boolean isCanceled();
    }

                        String response = multipart.Execute();
