I am making a app in which user selects a file and uploads it to the server.If the user selects image from gallery the image is being uploaded properly,but when ever the user selects a file like txt or word file its giving me System out of memory exception.

Use this

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).

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 want to upload an image to web server.For that i have written code,but when ever i upload the file to web server instead of file name i am getting the image path.

When i use
fileName = String.valueOf(f);
dos.writeBytes("Content-Disposition: form-data; name=\"uploaded_file\";filename=\"hello" + fileName + "\"" + lineEnd);
at server side i am getting the file name as the path of image.
And when i don't use
fileName = String.valueOf(f);
i am gettin the proper file name but i am not getting the extension of the image.
Now how can i solve this problem because the peoblem is in this line
dos.writeBytes("Content-Disposition: form-data; name=\"uploaded_file\";filename=\"hello" + fileName + "\"" + lineEnd);
You were using String.valueOf() in a file to get its name, it was returning an empty String, so it was not working.
Instead, you have to get the file name using file.getName().

For uploading video to server see doFileUpload() method from the above url.
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";
String twoHyphens = "--";
String boundary = "*****";
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1*1024*1024;
String urlString = "http://myUrl.com/uploadimg.php";
try
{
FileInputStream fileInputStream = new FileInputStream(photo[0].toString());
// 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=\"" + photo[0] +"\"" + 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 (IOException ioe) { Log.e("MediaPlayer", "error: " + ioe.getMessage(), ioe); }
try {
inStream = new DataInputStream (conn.getInputStream());
String str;
while ((str = inStream.readLine()) != null)
{

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 {
