The code i use for uploading files is :

privateboolean uploadFile(File file, String urlString) {

boolean isUploadOk = false;
HttpURLConnection conn = null;
DataOutputStream dos = null;
FileInputStream fileInputStream = null;

int maxBufferSize = 4096;

try {

// Open a HTTP connection to the URL
URL url = new URL(urlString);
conn = (HttpURLConnection) url.openConnection();

// Allow Inputs
conn.setDoInput(true);
// Allow Outputs
conn.setDoOutput(true);
// Don't use a cached copy.
conn.setUseCaches(true);
// Use a post method.
conn.setRequestMethod("PUT");
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=\""
+ file.getAbsolutePath() + "\";filename=\""
+ file.getName() + "\"" + lineEnd);
dos.writeBytes(lineEnd);

Log.e("", "Headers are written");

// create a buffer of maximum size
fileInputStream = new FileInputStream(file);
int bytesAvailable = fileInputStream.available();
int bufferSize = Math.min(bytesAvailable, maxBufferSize);

byte[] buffer = newbyte[bufferSize];

// read file and write it into form...
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.flush();
}

buffer = null;

// send MULTIPART/FORM data necessary after file data.!
dos.writeBytes(lineEnd);
dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);

// close streams
Log.e("fileupload", "File is written");


} catch (MalformedURLException ex) {
Log.e("fileupload", "error: " + ex.getMessage(), ex);
}
catch (IOException ioe) {
Log.e("Exception:: ", "error: " + ioe.getMessage(), ioe);

}finally
{
try
{
if(fileInputStream != null)
fileInputStream.close();

}catch (Exception e) {

}

try
{
if(dos != null)
{
dos.flush();
//dos.close();
}

}catch (Exception e) {

}

try
{
if(dos != null)
{

dos.close();
}

}catch (Exception e) {

}

}



return isUploadOk;
