show ProgressBar while file is uploading

I wrote a code in the Android project that uploads a file with a specific name and address to the server. But ProgressBar does not work well and does not show progress and file upload percentage. But the file upload works well and is located on the server. Now I want to show the percentage of progress in the Progress bar when uploading the file to the server to determine how much of the file has been uploaded to the server.
I tried to do this with AsyncTask.
My code ...
private class UploadTask extends AsyncTask<String, Integer, String> {
private final Context context;
public UploadTask(Context context) {
this.context = context;
}
#Override
protected String doInBackground(String... sUrl) {
// take CPU lock to prevent CPU from going off if the user
// presses the power button during download
PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK,
getClass().getName());
wl.acquire(10 * 60 * 1000L /*10 minutes*/);
try {
String fileName = uploadFilePath + uploadFileName;
HttpURLConnection conn = null;
DataOutputStream dos = null;
String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary = "*****";
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1 * 1024 * 1024;
File sourceFile = new File(uploadFilePath + uploadFileName);
if (!sourceFile.isFile()) {
dialog.dismiss();
Log.e("uploadFile", "Source File not exist :"
+ uploadFilePath + "" + uploadFileName);
getActivity().runOnUiThread(new Runnable() {
#SuppressLint("SetTextI18n")
public void run() {
messageText.setText("Source File not exist :"

Sneaker.with(getActivity())

Hidden Uploading file

I have one source for upload file from SDCard with have path and Name of file .
this cod works correctly . now I want to automatic run this code in service ( in background ) . can you help me to combine this cod in service ???
this code is for upload file by path and name of file... :

It look like you need to update the content on server side; to do so you can implement sync adapter framework. It will trigger the upload or download for you at per the scheduled task.

Now files gets uploaded however all file size of 1 MB and that too can not be played.

bufferSize = Math.min(bytesAvailable, maxBufferSize);
buffer = new byte[bufferSize];
byte byt[]=new byte[bufferSize];
fileInputStream.read(byt);
You are not writing the bytes read into byt out to the outputstream. Removing the first read into byt should fix a problem. But you will come across another problem where a file over 1MB only the first 1MB will be uploaded.
A proper way to copy a stream is to do something similar to
byte[] buf = new byte[ 1024 ];
int read = 0;
while( ( read = in.read( buf ) ) != -1 ) {
out.write( buf, 0, read );
}

avoid buffering the whole POST data in RAM by adding conn.setChunkedStreamingMode(0); after : con.setDoOutput(true);
hope this help :)

How do I post key/value pairs with a file upload in android

I know this is the repeat question.There are many similar questions are there in stack overflow but I am asking this question because I don't understand how I can post some data with Image.
I want to pass first name and last name with the image to the server.
Still now i tried this.
URL connectURL;
connectURL = new URL("some URL");
File sdImageMainDirectory = new File("/sdcard");
String existingFileName = sdImageMainDirectory.toString() +"/image.jpg";
String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary = "*****";
String Tag="3rd";
try
{
HttpURLConnection conn = (HttpURLConnection) connectURL.openConnection();
conn.setDoInput(true);
conn.setDoOutput(true);
conn.setUseCaches(false);
conn.setRequestMethod("POST");
conn.setRequestProperty("Connection", "Keep-Alive");
conn.setRequestProperty("Content-Type", "multipart/form-data;boundary="+boundary);
DataOutputStream dos = new DataOutputStream( conn.getOutputStream() );
dos.writeBytes(twoHyphens + boundary + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name=\"firstname\"" + lineEnd);
dos.writeBytes("Dharmendra");
dos.writeBytes(lineEnd);
dos.writeBytes(twoHyphens + boundary + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name=\"lastname\"" + lineEnd);
dos.writeBytes("Patel");
dos.writeBytes(lineEnd);
dos.writeBytes(twoHyphens + boundary + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name=\"uploadedfile\";filename=\"" + existingFileName +"\"" + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name=\"uploadedfile\";filename=\"" + existingFileName +"\"" + lineEnd);
dos.writeBytes(lineEnd);
int bytesAvailable = fileInputStream.available();
int maxBufferSize = 1024;
int bufferSize = Math.min(bytesAvailable, maxBufferSize);
byte[] buffer = new byte[bufferSize];
int bytesRead = fileInputStream.read(buffer, 0, bufferSize);
while (bytesRead > 0) {
dos.write(buffer, 0, bufferSize);
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
}
dos.writeBytes(lineEnd);
dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);
fileInputStream.close();
dos.flush();
dos.close();
}catch (MalformedURLException ex) {
Log.e(Tag, "error: " + ex.getMessage(), ex);
}
catch (IOException ioe) {
Log.e(Tag, "error: " + ioe.getMessage(), ioe);
}

Check this Code for adding additional Values to Uploading Image to Server :
public class Task_TurnoutPost extends AsyncTask<Void, Void, Void> {
private final ProgressDialog dialog = new ProgressDialog(ActivityName.this);
JSONObject object_feed;
// can use UI thread here
protected void onPreExecute() {
this.dialog.setMessage("Loading...");
this.dialog.setCancelable(false);
this.dialog.show();
}
#Override
protected Void doInBackground(Void... arg0) {
// TODO Auto-generated method stub
try {
HttpClient httpClient = new DefaultHttpClient();
HttpPost postRequest = new HttpPost("Your LINK");
MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
reqEntity.addPart("F_Name", new StringBody("F_Name"));
reqEntity.addPart("L_Name",new StringBody("L_NAME"));
try{
ByteArrayOutputStream bos = new ByteArrayOutputStream();
bitmap.compress(CompressFormat.JPEG, 75, bos);
byte[] data = bos.toByteArray();
ByteArrayBody bab = new ByteArrayBody(data, "forest.jpg");
reqEntity.addPart("picture", bab);
}catch(Exception e){
//Log.v("Exception in Image", ""+e);
reqEntity.addPart("picture", new StringBody(""));
}
postRequest.setEntity(reqEntity);
HttpResponse response = httpClient.execute(postRequest);
BufferedReader reader = new BufferedReader(new InputStreamReader(response.getEntity().getContent(), "UTF-8"));
String sResponse;
StringBuilder s = new StringBuilder();
while ((sResponse = reader.readLine()) != null) {
s = s.append(sResponse);
}
object_feed = new JSONObject(s.toString());
success_response=object_feed.getString("status");
Log.v("Response for POst", s.toString());
} catch (Exception e) {
Log.e("e.getClass().getName()", ""+e);
}
return null;
}
#Override
protected void onPostExecute(Void result) {
if (this.dialog.isShowing()) {
this.dialog.dismiss();
}
}
}
Where bitmap is your as Bitmap. In addition to it add a library and download it
Check this for you reference

I would actually use the Http headers here to post the key value pairs. Like this
conn.setRequestProperty("firstName", "Stephen");
conn.setRequestProperty("lastName", "glansburg");
Then on your server side you can just look at the http headers for that meta information.
