I've ben stuck on this for a while. I have an asynch task that uploads an image to a web server. Works fine.
I'm have a progress bar dialog set up for this. My problem is how to accurately update the progress bar. Everything I try results in it going from 0-100 in one step. It doesn't matter if it takes 5 seconds or 2 minutes. The bar hangs onto 0 then hits 100 after the upload is done.
Here's my doInBackground code. Any help is appreciated.
EDIT: I updated the code below to include the entire AsynchTask
private class UploadImageTask extends AsyncTask<String,Integer,String> {
private Context context;
private String msg = "";
private boolean running = true;
public UploadImageTask(Activity activity) {
this.context = activity;
dialog = new ProgressDialog(context);
dialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
dialog.setMessage("Uploading photo, please wait.");
dialog.setMax(100);
dialog.setCancelable(true);
}
#Override
protected void onPreExecute() {
dialog.show();
dialog.setOnDismissListener(mOnDismissListener);
}
#Override
protected void onPostExecute(String msg){
try {
// prevents crash in rare case where activity finishes before dialog
if (dialog.isShowing()) {
dialog.dismiss();
}
} catch (Exception e) {
}
}
#Override

dialog.setProgress(progress[0]);
}

You need to do the division on float values and convert the result back to int:
float progress = ((float)sentBytes/(float)fileSize)*100.0f;
publishProgress((int)progress);
You can do like:
try { // open a URL connection to the Servlet
FileInputStream fileInputStream = new FileInputStream(
sourceFile);
URL url = new URL("http://10.0.2.2:9090/plugins/myplugin/upload");
conn = (HttpURLConnection) url.openConnection();
conn.setDoInput(true); // Allow Inputs
conn.setDoOutput(true); // Allow Outputs
conn.setUseCaches(false); // Don't use a Cached Copy
conn.setRequestMethod("POST");
conn.setRequestProperty("Connection", "Keep-Alive");
conn.setRequestProperty("ENCTYPE", "multipart/form-data");
conn.setRequestProperty("Content-Type",
"multipart/form-data;boundary=" + boundary);
conn.setRequestProperty("uploadedfile", filename);
// conn.setFixedLengthStreamingMode(1024);
// conn.setChunkedStreamingMode(1);
dos = new DataOutputStream(conn.getOutputStream());
dos.writeBytes(twoHyphens + boundary + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name=\"uploadedfile\";filename=\""
+ filename + "\"" + lineEnd);
dos.writeBytes(lineEnd);
bytesAvailable = fileInputStream.available();
bufferSize = (int) sourceFile.length()/200;//suppose you want to write file in 200 chunks
buffer = new byte[bufferSize];
int sentBytes=0;
// read file and write it into form...
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
while (bytesRead > 0) {
dos.write(buffer, 0, bufferSize);
// Update progress dialog
sentBytes += bufferSize;
publishProgress((int)(sentBytes * 100 / bytesAvailable));
bytesAvailable = fileInputStream.available();
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
}
// send multipart form data necesssary after file data...
dos.writeBytes(lineEnd);
dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);
// Responses from the server (code and message)
serverResponseCode = conn.getResponseCode();
String serverResponseMessage = conn.getResponseMessage();
// close streams
fileInputStream.close();
dos.flush();
dos.close();
} catch (MalformedURLException ex) {
ex.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
I had the same problem and this helped me. This can help you too.
In your Async task class, write (paste) the following code.
ProgressDialog dialog;
protected void onPreExecute(){
//example of setting up something
dialog = new ProgressDialog(your_activity.this);
dialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
dialog.setMax(100);
dialog.show();
}
#Override
protected String doInBackground(String... params) {
for (int i = 0; i < 20; i++) {
publishProgress(5);
try {
Thread.sleep(88);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
dialog.dismiss();
return null;
}
protected void onProgressUpdate(Integer...progress){
dialog.incrementProgressBy(progress[0]);
}
If error occurs, remove "publishProgress(5);" from the code. Otherwise its good to go.
I spend two days with this example.
And all in this string.
conn.setRequestProperty("ENCTYPE", "multipart/form-data");
Only it helps.

Use this
library for multipart requests, i-e image, video or any other data for POST request
I'm uploading a file and want to display a progress dialog to see the upload progress. I already included a horizontal dialog which works incorrectly, because it goes to 100% in 1 second and then it waits (because it's still uploading).
I used the following function for uploading:
private void doFileUpload(String selectedPath){
HttpURLConnection conn = null;
DataOutputStream dos = null;
DataInputStream inStream = null;
String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary = "*****";
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1*1024*1024;
String responseFromServer = "";
String urlString = "https://xxxxxxxxxx.com";
try
{
//------------------ CLIENT REQUEST
File f = new File(selectedPath);
FileInputStream fileInputStream = new FileInputStream(f);
//calculate size of file
wholeFilesize = f.length(); //returns the length in Bytes
// open a URL connection to the Servlet
URL url = new URL(urlString);
// Open a HTTP connection to the URL
conn = (HttpURLConnection) url.openConnection();
// Allow Inputs
conn.setDoInput(true);
// Allow Outputs
conn.setDoOutput(true);
// Don't use a cached copy.
conn.setUseCaches(false);
// Use a post method.
conn.setRequestMethod("POST");
conn.setRequestProperty("Connection", "Keep-Alive");
conn.setRequestProperty("Content-Type", "multipart/form-data;boundary="+boundary);
dos = new DataOutputStream( conn.getOutputStream() );
dos.writeBytes(twoHyphens + boundary + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name=\"upfile\";filename=\"" + selectedPath + "\"" + lineEnd);
dos.writeBytes(lineEnd);
// create a buffer of maximum size
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
buffer = new byte[bufferSize];
// read file and write it into form...
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
while (bytesRead > 0)
{
totalReadFilesize+=bytesRead;
dos.write(buffer, 0, bufferSize);
bytesAvailable = fileInputStream.available();
int progress = (int)((totalReadFilesize*100)/(wholeFilesize));
//Log.i("Progress: ", (int)((totalReadFilesize*100)/(wholeFilesize))+"");
dialog.setProgress(progress);
bufferSize = Math.min(bytesAvailable, maxBufferSize);
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
}
//publishProgress(100);
Log.i("Size: ", wholeFilesize+"");
Log.i("Bytes read: ", totalReadFilesize+"");
// send multipart form data necesssary after file data...
dos.writeBytes(lineEnd);
dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);
// close streams

fileInputStream.close();
dos.flush();
dos.close();

{

}
//------------------ read the SERVER RESPONSE
try {
inStream = new DataInputStream ( conn.getInputStream() );
String str;
while (( str = inStream.readLine()) != null)

Log.e("Debug","Server Response "+str);
JSONObject jsonObj = new JSONObject(str);
//String status=(String) jsonObj.get("status");

Does someone know, how should I modify the code to see the real progress of the file, which is being uploaded? I find it strange, because I'm doing the same as the user in his doInBackground() in this thread.
I have got an app that can take a picture and deliver me an uri of the given picture.
Next thing, I want to do is send this picture to my webservices.
But, Once i tried that, i got an error that i have had before, which relates to asynctask. So tried to work around it, i have got a HttpManager class which holds the information on how to connect to the webservice, the url itself and where it handles the image uri.
public static String uploadImageToWebservice(String uri, String imageUri) {
HttpURLConnection connection = null;
int responseCode = 0;
String image = "";
try {
URL url = new URL(uri + imageUri);
connection = (HttpURLConnection) url.openConnection();
connection.setDoOutput(true);
connection.setInstanceFollowRedirects(false);
connection.setRequestMethod("GET");
connection.setRequestProperty("Content-Type", "text/plain");
/*
* String userpassword = adminUser + ":" + adminPassword; String
* encodedAuthorization = DatatypeConverter
* .printBase64Binary(userpassword.getBytes("UTF-8"));
* connection.setRequestProperty("Authorization", "Basic " +
* encodedAuthorization);
*/
InputStream is = connection.getInputStream();
image = is.toString();
responseCode = connection.getResponseCode();
connection.disconnect();
} catch (IOException e) {
Log.e("URL", "failure response from server >" + e.getMessage()
+ "<");
} finally {
if (connection != null) {
connection.disconnect();
}
}
return image;
}
And this is how i handle this method in my activity.
private void submitImage(String uri) {
HttpAsyncTask at = new HttpAsyncTask();
at.execute(uri);
}
private class HttpAsyncTask extends AsyncTask<String, String, String> {
#Override
protected String doInBackground(String... params) {
String image = HttpManager.uploadImageToWebservice(params[0],
params[1]);
return image;
}
}
And then i call the submitImage method in the oncreate with the Uri of the webservice.
But I'm kind of stuck on where to put in the uri of the image itself for it to be sent as well. I just feel like I'm missing something and i can't figure out where it is. Hopefully its to understand all of this.
Thanks in advance!

It works fine but,the file contains 20 lines it saved in the sever with 22 lines.
My actual file looks like as follows.
android app info
app name
app time
when i will send the flle to server from sd card the file look like as follows
1)**mnt/sdcard/111**
android app info
app name
app time
2)**
1 and 2 lines are added.
How i can send a file without those two lines .
If any one know the solution please help me .

Call new loadVideo().execute(); where ever you needed.
And add the following class to do the video loading.
public class loadVideo extends AsyncTask<Void, Void, Void>
{
private final ProgressDialog dialog = new ProgressDialog(

protected void onPreExecute() {
this.dialog.setMessage("Loading...");
this.dialog.setCancelable(false);
this.dialog.show();
}
protected void onPostExecute(Void result) {
if (this.dialog.isShowing()) {
this.dialog.dismiss();
}
}
});
}
#Override
protected Void doInBackground(Void... params) {
HttpURLConnection conn = null;
DataOutputStream dos = null;
DataInputStream inStream = null;
String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary = "*****";
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 8*1024*1024;

make this call before starting network comm...
ProgressDialog dialog = ProgressDialog.show(this, "", "Loading");
call the below after completion..
dialog.dismiss();
...
Its better to use AsyncTask for network communications
This question might help you. Basically you need to make a ProgressDialog in onPreExecute() method of AsyncTask and dismiss it in onPostExecute().
Upload code will go in the doInBackGround() method of AsyncTask.
