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", "abc@gmail.com");
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 .

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);
}
}
}

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

and call this way

multipart.addFilePart("file", mFile);
