I want to show progress bar while uploading a video from my app to php server.The below will upload the file to the server correctly.But i dont know how to show the progress bar.If anybody knows pls help me.
Here is my code:
private void doFileUpload(){
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;
Cursor c = (MainscreenActivity.JEEMAHWDroidDB).query((MainscreenActivity.TABLE_Name), new String[] {
(MainscreenActivity.COL_HwdXml)}, null, null, null, null,
null);
if(c.getCount()!=0){
c.moveToLast();
for(int i=c.getCount()-1; i>=0; i--) {
value=c.getString(0);
}
}
String urlString = value+"/upload_file.php";
try
{
//------------------ CLIENT REQUEST
UUID uniqueKey = UUID.randomUUID();
fname = uniqueKey.toString();
Log.e("UNIQUE NAME",fname);
FileInputStream fileInputStream = new FileInputStream(new File(selectedPath) );
URL url = new URL(urlString);
conn = (HttpURLConnection) url.openConnection();
conn.setDoInput(true);

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.

Why don't you try like this,
try {
HttpClient httpClient = new DefaultHttpClient();
String url = "http://thinksl.com/taughtable/audiopost.php";
HttpPost httppost = new HttpPost(url);
MultipartEntity reqEntity = new MultipartEntity();
reqEntity.addPart("file", new FileBody(new File(path)));
reqEntity.addPart("filename", final_upload_filename);
httppost.setEntity(reqEntity);
HttpResponse response = httpClient.execute(httppost);
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);
}
System.out.println("Response: " + s);
Log.e(TAG, "Response: " + s);
status = "" + s;
} catch (Exception e) {
e.printStackTrace();
}
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:

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

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...

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'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

dialog.setOnDismissListener(mOnDismissListener);
}
#Override

Reference : http://delimitry.blogspot.in/2011/08/android-upload-progress.html
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.
I'm trying to upload more than one image taken from the camera. I call the camera via Intent:
public void TakePicture(int actionCode)
{
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
try
{
photo[0] = createTemporaryFile("spot", ".jpg");
}
catch(Exception e)
{
Log.v("ERROR SD!!", "Can't create file to take picture!");
Toast.makeText(this, "Please check SD card! Image shot is impossible!", 10000);
}
fileUri = Uri.fromFile(photo[0]);
intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
}
And then I upload it to a PHP server:
public void UploadImg()
{
HttpURLConnection conn = null;
DataOutputStream dos = null;
DataInputStream inStream = null;
// String exsistingFileName = "/sdcard/prueba.png"; --> Used for local files!!
String lineEnd = "\r\n";

I save 3 different images: photo[0], photo[1] and photo[2]. The problem is that when I take, for example, two pictures, it only uploads one of them and with size = 0.
In the code of the UploadImg() I show only the photo[0], but in the 'real' code I use a for loop after the first try so that it upload all of the images taken.
Any idea of what am I doing wrong?
Thank you very much in advance!
I've already solved my problem! I did the following: Instead of saving the photo File, I save the it in a String with the location of the image.
if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) {
if (resultCode == RESULT_OK) {
for (int u = 0; u <= 2; u++)
{
if (savedImgs[u].equals(""))
{
// Saving important info to be used later
imgs = u + 1;
savedImgs[u] = photo.toString();
break;
}
} ...
And then, when uploading the images to the server, I make a for loop like this:
public void UploadImg()
{
HttpURLConnection conn = null;
DataOutputStream dos = null;
DataInputStream inStream = null;
// String exsistingFileName = "/sdcard/prueba.png"; --> Used for local files!!
String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary = "*****";
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1*1024*1024;
String urlString = "http://myUrl.com/uploadimg.php";
for (int n = 0; n < imgs; n++)
{
try
{
FileInputStream fileInputStream = new FileInputStream(savedImgs[n]);
// Open a URL connection to the Servlet
URL url = new URL(urlString);
// Open a HTTP connection to the URL
conn = (HttpURLConnection) url.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);
dos = new DataOutputStream(conn.getOutputStream());
dos.writeBytes(twoHyphens + boundary + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name=\"uploadedfile\";filename=\"" + savedImgs[n] +"\"" + 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)
{
dos.write(buffer, 0, bufferSize);
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
}
// 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();
}
catch (MalformedURLException ex) { Log.e("MediaPlayer", "error: " + ex.getMessage(), ex); }
catch (IOException ioe) { Log.e("MediaPlayer", "error: " + ioe.getMessage(), ioe); }
try {
inStream = new DataInputStream (conn.getInputStream());
String str;
while ((str = inStream.readLine()) != null)
{
System.out.println("Server Response" + str);
}
inStream.close();
}
catch (IOException ioex) { Log.e("MediaPlayer", "error: " + ioex.getMessage(), ioex); }

I want to copy all the video files on my server & save it in the web contents folder of a web service , so that it can be visible to all later on !
How should i proceeed ?
Basically you need two sides. The first one is on Android. You have to send (Do it in an ASyncTask e.x.) the data to your webservice. Here I made a little method for you, which sends a file and some additional POST values to an URL:
private boolean handleFile(String filePath, String mimeType) {
HttpURLConnection connection = null;
DataOutputStream outStream = null;
DataInputStream inStream = null;
String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary = "*****";
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1*1024*1024;
String urlString = "http://your.domain.com/webservice.php";
try {
FileInputStream fileInputStream = null;
try {
fileInputStream = new FileInputStream(new File(filePath));
} catch(FileNotFoundException e) { }
URL url = new URL(urlString);
connection = (HttpURLConnection) url.openConnection();
connection.setDoInput(true);
connection.setDoOutput(true);
connection.setUseCaches(false);
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(getBaseContext());
connection.setRequestMethod("POST");
connection.setRequestProperty("Connection", "Keep-Alive");
connection.setRequestProperty("Content-Type", "multipart/form-data;boundary="+boundary);
outStream = new DataOutputStream(connection.getOutputStream());
// Some POST values
outStream.writeBytes(addParam("additional_param", "some value");
outStream.writeBytes(addParam("additional_param 2", "some other value");
// The file with the name "uploadedfile"
outStream.writeBytes(twoHyphens + boundary + lineEnd);
outStream.writeBytes("Content-Disposition: form-data; name=\"uploadedfile\";filename=\"" + filePath +"\"" + lineEnd + "Content-Type: " + mimeType + lineEnd + "Content-Transfer-Encoding: binary" + lineEnd);
outStream.writeBytes(lineEnd);
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
buffer = new byte[bufferSize];
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
while (bytesRead > 0) {
outStream.write(buffer, 0, bufferSize);
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
}
outStream.writeBytes(lineEnd);
outStream.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);
fileInputStream.close();
outStream.flush();
outStream.close();
} catch (MalformedURLException e) {
Log.e("APP", "MalformedURLException while sending\n" + e.getMessage());
} catch (IOException e) {
Log.e("APP", "IOException while sending\n" + e.getMessage());
}
// This part checks the response of the server. If its "UPLOAD OK" the method returns true
try {
inStream = new DataInputStream( connection.getInputStream() );
String str;
while (( str = inStream.readLine()) != null) {
if(str=="UPLOAD OK") {
return true;
} else {
return false;
}
}
inStream.close();
} catch (IOException e){
Log.e("APP", "IOException while sending\n" + e.getMessage());
}
return false;
}
Now, we have got the other side: http://your.domain.com/webservice.php
Your server. It needs some logic, for example in PHP, to handle the sent POST request.
Something like this would work:
<?php
$target_path = "videos/";
$target_path = $target_path.'somename.3gp';
if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
exit("UPLOAD OK");
} else {
exit("UPLOAD NOT OK");
}
?>
