Check out this tutorial - http://www.androidhive.info/2014/12/android-uploading-camera-image-video-to-server-with-progress-bar/
private class UploadFileToServer extends AsyncTask<Void, Integer, String> {
@Override
protected void onPreExecute() {
// setting progress bar to zero
progressBar.setProgress(0);
super.onPreExecute();
}
@Override
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;
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(Config.FILE_UPLOAD_URL);
try {
AndroidMultiPartEntity entity = new AndroidMultiPartEntity(
new ProgressListener() {
@Override
public void transferred(long num) {
publishProgress((int) ((num / (float) totalSize) * 100));
}
});
File sourceFile = new File(filePath);
// Adding file data to http body
entity.addPart("image", new FileBody(sourceFile));
// Extra parameters if you want to pass to server
entity.addPart("website",
new StringBody("www.androidhive.info"));
entity.addPart("email", new StringBody("[email protected]"));
totalSize = entity.getContentLength();
httppost.setEntity(entity);
// Making server call
HttpResponse response = httpclient.execute(httppost);
HttpEntity r_entity = response.getEntity();
int statusCode = response.getStatusLine().getStatusCode();
if (statusCode == 200) {
// Server response
responseString = EntityUtils.toString(r_entity);
} else {
responseString = "Error occurred! Http Status Code: "
+ statusCode;
}
} catch (ClientProtocolException e) {
responseString = e.toString();
} catch (IOException e) {
responseString = e.toString();
}
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);
}
}

Take a look at this gist, there you can find full working exaple
First you have to create a custom RequestBody with an interface witch will update your progress bar.
import com.squareup.okhttp.MediaType;
import com.squareup.okhttp.RequestBody;
import com.squareup.okhttp.internal.Util;
import java.io.File;
import java.io.IOException;
import okio.BufferedSink;
import okio.Okio;
import okio.Source;
public class ProgressRequestBody extends RequestBody {
private static final int SEGMENT_SIZE = 2048; // okio.Segment.SIZE
private final File file;
private final ProgressListener listener;
private final String contentType;
public ProgressRequestBody(File file, String contentType, ProgressListener listener) {
this.file = file;
this.contentType = contentType;
this.listener = listener;
}
@Override
public long contentLength() {
return file.length();
}
@Override
public MediaType contentType() {
return MediaType.parse(contentType);
}
@Override
public void writeTo(BufferedSink sink) throws IOException {
Source source = null;
try {
source = Okio.source(file);
long total = 0;
long read;
while ((read = source.read(sink.buffer(), SEGMENT_SIZE)) != -1) {
total += read;
sink.flush();
this.listener.transferred(total);
}
} finally {
Util.closeQuietly(source);
}
}
public interface ProgressListener {
void transferred(long num);
}
}
you can copy this class as is
Now in your activity or fragment implement the ProgressListener from the ProgressRequestBody class and call a following methods
public void uploadWithProgrss(File file) {
RequestBody requestBody = new MultipartBuilder()
//build multipart request
.type(MultipartBuilder.FORM)
//name= KEY for your param
//filename = VALUE of the param - in our case filename
//attach the custom ProgressRequestBody in form of (File file, String type, Interface ProgressRequestBody.ProgressListener)
//Set type depending on your content type if video set it to "video/mp4" or "image/jpeg" if image
.addPart(Headers.of("Content-Disposition", "form-data; name=\"digital_product[attachment]\"; filename=\"" + file.getName() + "\""),
new ProgressRequestBody(file, type2, this))
//attach the rest of Request body parameters if any
.addPart(
Headers.of("Content-Disposition", "form-data; name=\"digital_product[price]\""),
RequestBody.create(MediaType.parse("text/plain"), etPrice.getText().toString()))
.addPart(
Headers.of("Content-Disposition", "form-data; name=\"digital_product[title]\""),
RequestBody.create(MediaType.parse("text/plain"), etCaption.getText().toString()))
.addPart(
Headers.of("Content-Disposition", "form-data; name=\"digital_product[description]\""),
RequestBody.create(MediaType.parse("text/plain"), etCaption.getText().toString()))
.build();
//Build your request
Request request = new Request.Builder()
//your url
.url(BuildConfig.API_URL + "api/v1/users/me/digital_products")
//request header if any
.addHeader("Authorization", "Bearer " + app.getAccessToken())
//type of the request, i this case post request with request body
.post(requestBody)
.build();
client.setReadTimeout(1, TimeUnit.MINUTES);
client.setConnectTimeout(1, TimeUnit.MINUTES);
client.setWriteTimeout(1, TimeUnit.MINUTES);
final Call call = client.newCall(request);
call.enqueue(new com.squareup.okhttp.Callback() {
@Override
public void onFailure(Request request, IOException e) {
}
@Override
public void onResponse(com.squareup.okhttp.Response response) throws IOException {
if (response.isSuccessful()) {
//Handle success
} else {
call.cancel();
//handle error
}
}
});
}
@Override
public void transferred(final long num) {
//progress bar had to be updated from the UI thread
new Handler(activity.getMainLooper()).post(new Runnable() {
@Override
public void run() {
//just chacking if fragment is added
if (isAdded()) {
//Updating progress bar
progressBar.setProgress((int) ((num / (float) file.length()) * 100));
}
}
});
}

protected class upload_images extends AsyncTask<String, Integer, String> {
ProgressDialog progressDialog;
@Override
protected void onPreExecute() {
super.onPreExecute();
// showDialog(progress_bar_type);
progressDialog = new ProgressDialog(Accept_Report.this);
progressDialog.setCancelable(false);
// dialog.setCanceledOnTouchOutside(false);
progressDialog.setIndeterminate(false);
// progressDialog.setMax(100);
progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
// progressDialog.setProgress(0);
progressDialog.setMax(100);
// progressDialog.setMessage("Loading ...");
progressDialog.show();
// ProgressBar progressBar = (ProgressBar)findViewById(R.id.progressBar2);
}
@Override
protected String doInBackground(String... params) {
URL url;
HttpURLConnection connection = null;
String http = Util.URL + "reports/media/create";
try {
url = new URL(http);
connection = (HttpURLConnection) url.openConnection();
.
.
.
connection.connect();
...
// you are doing this
// what is jsonParam ?
//byte[] payload = jsonParam.toString().getBytes("UTF-8");
// how you gonna get content lenght from it?
int count = 0;
OutputStream wr = connection.getOutputStream();
InputStream inputStream = null;
byte[] payload = jsonParam.toString().getBytes("UTF-8");
int totalSze = payload.length;
Log.e("Total size ", "" + totalSze);
int bytesTransferred = 0;
int chunkSize = (2 * totalSze) / 100;
boolean last_loop = false;
// publishProgress(0);
...
// Do like this example
// getting file length
int lenghtOfFile = connection.getContentLength();
// input stream to read file - with 8k buffer
InputStream input = new BufferedInputStream(url.openStream(), 8192);
// Output stream to write file
OutputStream output = new FileOutputStream("/sdcard/downloadedfile.jpg");
byte data[] = new byte[1024];
long total = 0;
while ((count = input.read(data)) != -1) {
total += count;
// publishing the progress....
// After this onProgressUpdate will be called
publishProgress((int) ((total * 100) / lenghtOfFile));
// writing data to file
output.write(data, 0, count);
}
} catch (Exception e) {
}
return null;
}
@Override
protected void onProgressUpdate(Integer... values) {
super.onProgressUpdate(values);
// Log.e("dfsf",""+values[0]);
progressDialog.setProgress(values[0]);
// progressDialog.setProgress(values[0]);
}
@Override
protected void onPostExecute(String result) {
if (HttpResultimage == 204) {
progressDialog.dismiss();
}
}
}

I am uploading string and photo.and its working fine. Now I want to show progress bar while uploading data with percentage but percentage show very quickly to 100 percentage and take some more time to upload and finally come to the post execute method.
protected class upload_images extends AsyncTask<String, Integer, String> { ProgressDialog progressDialog; @Override protected void onPreExecute() { super.onPreExecute(); // showDialog(progress_bar_type); progressDialog = new ProgressDialog(Accept_Report.this); progressDialog.setCancelable(false); // dialog.setCanceledOnTouchOutside(false); progressDialog.setIndeterminate(false); // progressDialog.setMax(100); progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL); // progressDialog.setProgress(0); progressDialog.setMax(100); // progressDialog.setMessage("Loading ..."); progressDialog.show(); // ProgressBar progressBar = (ProgressBar)findViewById(R.id.progressBar2); } @Override protected String doInBackground(String... params) { URL url; HttpURLConnection connection = null; String http=Util.URL+"reports/media/create"; try { url = new URL(http); connection = (HttpURLConnection) url.openConnection(); connection.setDoInput(true); connection.setRequestMethod("POST"); /* connection.setConnectTimeout(50000); connection.setReadTimeout(50000);*/ connection.setRequestProperty("Content-Type", "application/json"); connection.setRequestProperty("Content-Language", "en-US"); String encoded = Base64.encodeToString(("app" + ":" + "sFif4au7wet8gpsT0boK1oM2Yud6M1").getBytes("UTF-8"), Base64.NO_WRAP); connection.setRequestProperty("Authorization", "Basic " + encoded); connection.setUseCaches(false); connection.setDoOutput(true); connection.connect(); jsonArray = new JSONArray(); right = send_right.toString().replaceAll("\\[", "").replaceAll("\\]", ""); if((right!=null)&&(right!="")) { JSONObject pnObj = new JSONObject(); pnObj.put("comments", right_cm); pnObj.put("section", right_sec); pnObj.put("pictures", right); jsonArray.put(pnObj); } // return totalSize; JSONObject jsonParam = new JSONObject(); jsonParam.put("media", jsonArray); //Send request int count = 0; OutputStream wr = connection.getOutputStream(); InputStream inputStream = null; byte[] payload = jsonParam.toString().getBytes("UTF-8"); int totalSze = payload.length; Log.e("Total size ", "" + totalSze); int bytesTransferred = 0; int chunkSize = (2*totalSze)/100; boolean last_loop = false; // publishProgress(0); while (bytesTransferred < totalSze) { Log.e("bytes transferred", "" + bytesTransferred); int nextChunkSize = totalSze - bytesTransferred; Log.e("nextchunck",""+nextChunkSize); //int writer_size = wr.toString().getBytes("UTF-8").length; Log.e("chunk size", "" + chunkSize); if (nextChunkSize > chunkSize) { nextChunkSize = chunkSize; } wr.write(payload, bytesTransferred, nextChunkSize); bytesTransferred += nextChunkSize; Log.e("byte",""+wr.toString().getBytes("UTF-8").length); Log.e("progress-transferred", "" + bytesTransferred +" total "+totalSze); double cal = (( (double)bytesTransferred / (double) totalSze) * 100); double rounded = (double) Math.round(cal * 100.0) / 100.0; Log.e("progress",""+(int)rounded); publishProgress((int)rounded); wr.flush(); wr.close(); }catch(Exception e){ Log.d("Exception", e.toString()); } }*/ Log.e("While loop exit", ""); /* wr.flush (); wr.close();*/ }catch (OutOfMemoryError e) { e.printStackTrace(); } //Get Response StringBuilder sb = new StringBuilder(); HttpResultimage =connection.getResponseCode(); Log.e("res",""+HttpResultimage); if(HttpResultimage==204) { BufferedReader br = new BufferedReader(new InputStreamReader(connection.getInputStream(),"utf-8")); String line = null; while ((line = br.readLine()) != null) { sb.append(line + "\n"); } br.close(); System.out.println("" + sb.toString()); }else{ } } catch (Exception e) { e.printStackTrace(); return null; } finally { if(connection != null) { connection.disconnect(); } } return null; } @Override protected void onProgressUpdate(Integer... values){ super.onProgressUpdate(values); // Log.e("dfsf",""+values[0]); progressDialog.setProgress(values[0]); // progressDialog.setProgress(values[0]); } @Override protected void onPostExecute(String result) { if (HttpResultimage==204) { progressDialog.dismiss(); } } } -
Ajin kumar about 8 yearsabove httpclient methods are removed in marshmallow so i can't do it
-
Ajin kumar about 8 yearsI want to upload the data to server not the sd card
-
Sohail Zahid about 8 years@Ajinkumar its sample for counting no of bytes transfer ......and you haven't explain whatsjsonParamon which basis you publishing progress. -
Ajin kumar about 8 yearsI have just add some comments,section and picture(base64 string) to json array like this {"media":[{"comments":"","section":4,"pictures":"iVBORw0KGgoAAAANSUh"}] }. and add this json array to jsonParam(JSONObject variable) then send the JSONObject to server
