Progress bar in notification bar while uploading image to a server in Android

I am uploading image to a web server by picking the image from gallery or by capturing it using android camera.

I need to show a progress in the notification bar. I see the Facebook app does this. is there a way to find out how much has been uploaded?

My code for uploading the image to the server is :

public void uploadImage() {
    final Toast toast = Toast.makeText(this, "Image uploaded successfully",
        Toast.LENGTH_SHORT);
    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setTitle("Upload");
    builder.setMessage("Do you want to upload the captured picture?");
    builder.setIcon(R.drawable.icon);
    builder.setCancelable(false);
    builder.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int id) {
        testWebService(Bitmap bmp)
        finish();
        toast.show();

        }
    });
    builder.setNegativeButton("No", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int id) {

        dialog.cancel();

        }
    });
    AlertDialog alert = builder.create();
    alert.show();

}



public void testWebService(Bitmap bmp) {

    MarshalBase64 marshal = new MarshalBase64();
    ByteArrayOutputStream out = new ByteArrayOutputStream();
    bmp.compress(CompressFormat.PNG, 100, out);
    byte[] raw = out.toByteArray();

    SoapObject request = new SoapObject(WSDL_TARGET_NAMESPACE,
        OPERATION_NAME);

    request.addProperty("image", raw);

    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
        SoapEnvelope.VER11);
    envelope.dotNet = true;
    envelope.setOutputSoapObject(request);
    marshal.register(envelope);
    HttpTransportSE httpTransport = new HttpTransportSE(SOAP_ADDRESS);

    try

    {

        httpTransport.call(SOAP_ACTION, envelope);
        Object response = envelope.g开发者_StackOverflow中文版etResponse();
            }

    catch (Exception exception)

    {
        exception.printStackTrace();

    }

    }

Is there a way to find out how much has been uploaded?

This is useful link: http://developer.android.com/guide/topics/ui/notifiers/notifications.html#CustomExpandedView

Now use Progress Bar in your custom layout for your Notification.

This code is for tracing download. As this you can check upload status, start this Async task in a service to upload and update progress bar accordingly

 private class DownloadFilesTask extends AsyncTask<URL, Integer, Long> {
 protected Long doInBackground(URL... urls) {
     int count = urls.length;
     long totalSize = 0;
     for (int i = 0; i < count; i++) {
         totalSize += Downloader.downloadFile(urls[i]);
         publishProgress((int) ((i / (float) count) * 100));
     }
     return totalSize;
 }

 protected void onProgressUpdate(Integer... progress) {
     setProgressPercent(progress[0]);
 }

 protected void onPostExecute(Long result) {
     showDialog("Downloaded " + result + " bytes");
 }

I'm not familiar with the classes you're using to make your SOAP calls, but a common way of accomplishing upload progress with the Apache Commons HttpClient is to provide your own FilterOutputStream subclass that simply makes a callback to a specified listener every time part of the stream is read out. You just need to override the write() methods:

    @Override
    public void write(byte[] b, int off, int len) throws IOException {
        out.write(b, off, len);
        transferred += len;
        progressHandler.handleProgress(ProgressDirection.Send, len, transferred, expectedLength);
    }

    @Override
    public void write(int b) throws IOException {
        out.write(b);
        progressHandler.handleProgress(ProgressDirection.Send, 1, ++transferred, expectedLength);
    }

Of course, you can only use this method if your HTTP library allows you to provide the entire body (or at least a large portion) of your HTTP request as an OutputStream.
