i want to send file from our app to sever through http post method.
My code is looking like as fallows
HttpURLConnection conn = null;
DataOutputStream dos = null;
DataInputStream inStream = null;
String existingFileName = Environment.getExternalStorageDirectory().getAbsolutePath()
+ "/TamTrack/TamTrackDetails.xml";
String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary = "*****";
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1*1024*1024;
String responseFromServer = "";
String urlString = "http://192.158.1.7/Geo/myfilename";
try
{
//------------------ CLIENT REQUEST
FileInputStream fileInputStream = new FileInputStream(new File(existingFileName) );
// 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=\"uploadedfile\";filename=\"" + existingFileName + "\"" + 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)
Log.v("info",".size."+bytesRead);
for(int n1=0;n1<bytesRead;n1++)
{
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);
// close streams
Log.v("info","File is written");
fileInputStream.close();
dos.flush();
dos.close();
}
catch (MalformedURLException ex)
{
Log.v("info", "error: " + ex.getMessage(), ex);
}
catch (IOException ioe)
{
Log.v("info", "error: " + ioe.getMessage(), ioe);
}
//------------------ read the SERVER RESPONSE
try {

}
inStream.close();
}
catch (IOException ioex)
{
Log.v("info", "error: " + ioex.getMessage(), ioex);
}
return null;
It is working fine.but empty file is created in server.
If any one know the solution ,please help me .
Thanks in advance.
Try this code. It is using a class "SimpleMultipartEntity" using which you can easily send the file.
I'd prefer using Apache Http commons, it is part of android. I think this is a much simpler and cleaner approach. You need to do something like this:
AndroidHttpClient client = AndroidHttpClient.newInstance("useragent string");
URI uri = "something";
File file = new File("/tmp/data");
HttpPost post = new HttpPost(uri);
post.setEntity(new FileEntity(file, "text/html"));
HttpResponse httpResponse = client.execute(post);
int statusCode = httpResponse.getStatusLine().getStatusCode();

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:
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));

bufferSize = Math.min(bytesAvailable, maxBufferSize);
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
}
//publishProgress(100);

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 am trying to make an app that can connect android app to the server, and I need to upload and download 2 or more files
I found this code
private void doFileUpload() {
HttpURLConnection conn = null;
DataOutputStream dos = null;
DataInputStream inStream = null;
String existingFileName = Environment.getExternalStorageDirectory()
.getAbsolutePath() + "/android/data/[package]/files/productHistory";
**String existingFileName2 = Environment.getExternalStorageDirectory()
.getAbsolutePath() + "/android/data/[package]/files/productStock";**
String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary = "*****";
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1 * 1024 * 1024;
String responseFromServer = "";
String urlString = "http://192.168.1.112/johnson/learn/android/";
try {
// ------------------ CLIENT REQUEST
FileInputStream fileInputStream = new FileInputStream(new File(
existingFileName));
// 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);

// 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",

dos = new DataOutputStream(conn.getOutputStream());
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=\""
+ existingFileName2 + "\"" + 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);

Log.e("Debug", "error: " + ioex.getMessage(), ioex);
}
}
The bold text is edited by me,
but it is fail, it only upload the first one
my question is 1. how to upload 2/more files with the code?
2. and how to download them?
thanks in advance
Not sure if you have to use a specific server, yet Parse offers a sweet SDK with intuitive API to send/receive data (images in you case) to and from the server. I'd suggest you try that out if you don't want to spend to much time writing code that sends and receives data to and from a server. (and no, I don't work at Parse, just a big fan of their tools :P).
I need to upload a file from my android emulator directory ('data\data\org.mypackage\file.dat') to a remote server, but when I try to access the file it gives an error like 'error: Permission denied', I store my sqlite database in 'data\data\org.mypackage\databases\' folder , during the application startup if there is no sqlite db in that folder I copied it from my asset folder to that directory and access it from there it works perfect but in the case upload task it ask for permission why this occur? following is my uploadFile method

Add INTERNET permission to your manifest.
If you can provide logcat then it will help more.

can anyone suggest some idea to solve this.
I think error happened in follow line because DataOutputStream size is exceeds VM budget when you write
dos.write(buffer, 0, bufferSize);
