Sending a xml file to a web service in android

Hello Friends I am trying to send an xml file stored in my sd card through my android app with the piece of code below:

    public class CartDetailsActivity extends Activity {
    File newxmlfile = new File(Environment.getExternalStorageDirectory() + "/"+GlobalVariables.ada_login+".xml");

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.cart_details);

        Button payButton=(Button)findViewById(R.id.pay);
        payButton.setOnClickListener(new OnClickListener() 
        {

            @Override
            public void onClick(View arg0) {
                // TODO Auto-generated method stub
                new PostXmlClass().execute();
            }





    });
}

    public class PostXmlClass extends AsyncTask<Void, Void, Void> {

        private final ProgressDialog dialog = new ProgressDialog(
        CartDetailsActivity.this);

protected void onPreExecute() {
    this.dialog.setMessage("Loading...");
    this.dialog.setCancelable(false);
    this.dialog.show();
}
    @Override
    protected Void doInBackground(Void... params) {

        String url = "http://mywebsite.com/myfolder/mypage.php";

        try {
            HttpClient httpclient = new DefaultHttpClient();

            HttpPost httppost = new HttpPost(url);

            InputStreamEntity reqEntity = new InputStreamEntity(
                    new FileInputStream(newxmlfile), -1);
            reqEntity.setContentType("binary/octet-stream");
            reqEntity.setChunked(true); // Send in multiple parts if needed
            httppost.setEntity(reqEntity);
            HttpResponse response = httpclient.execute(httppost);
            //Do something with response...

        } catch (Exception e) {
            // show error
        } // inside the method paste your file uploading code
        return null;
    }

    protected void onPostExecute(Void result) {

        // Here if you wish to do future process for ex. move to another activity do here

        if (dialog.isShowing()) {
            dialog.dismiss();
        }

    }
}
}

xml file is of the type:

<?xml version='1.0' standalone='yes' ?>
<root>
  <item>
    <code>ACT358</code>
    <price>110.00</price>
    <quantity>3</quantity>
    <totalcost>330.0</totalcost>
  </item>

<item>
  <code>ACT443</code>
  <price>110.00</price>
  <quantity>2</quantity>
  <totalcost>220.0</totalcost>
</item>
</root>

I don't know whats wrong with this code as it is not working and file does not get uploaded. Any help will be appreciated.

I Tweaked your doInBackground to how i do the exact same thing: Give it a try:

     @Override
    protected Void doInBackground(Void... params) {

        String url = "http://mywebsite.com/myfolder/mypage.php";

        try {
            FileReader fr = new FileReader(newxmlfile);
            BufferedReader br = new BufferedReader(fr);
            StringBuffer sb = new StringBuffer();
            String line = "";
            while((line = br.readLine()) != null) {
                sb.append(line);
                sb.append("\n");
            }
            br.close();
            fr.close();
            String xml = sb.toString();


            HttpClient httpclient = new DefaultHttpClient();

            HttpPost httppost = new HttpPost(url);

            StringEntity se = new StringEntity(xml);
            se.setContentType("text/xml");
            httppost.setEntity(se);
            HttpResponse response = httpclient.execute(httppost);
            //Do something with response...

        } catch (Exception e) {
            // show error
        } // inside the method paste your file uploading code
        return null;
    }

I wrote a dictionary tutorial while back where i send xml to web service, Have a look at it here for more info Andorid Dictionary Tutorial

Try below code, hope this gonna help you.

PHP web-service

<?php
// Where the file is going to be placed
$target_path = "uploads/";

/* Add the original filename to our target path.
Result is "uploads/filename.extension" */
$target_path = $target_path . basename( $_FILES['uploadedfile']['name']);

if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
    echo "The file ".  basename( $_FILES['uploadedfile']['name']).
    " has been uploaded";
} else{
    echo "There was an error uploading the file, please try again!";
    echo "filename: " .  basename( $_FILES['uploadedfile']['name']);
    echo "target_path: " .$target_path;
}
?>

Java Code

String path = Environment.getExternalStorageDirectory() + "/"+GlobalVariables.ada_login+".xml"";
new uploadFiletoServer().execute(path);

and here is your uploadFile

class uploadFiletoServer extends AsyncTask<String, String, String> {
        @Override
        protected void onPreExecute() {
            super.onPreExecute();
            pDialog = new ProgressDialog(yourActivity.this);
            pDialog.setMessage("Uploading file to server. Please wait ...");
            pDialog.setIndeterminate(false);
            pDialog.setCancelable(false);
            pDialog.show();
        }

        @SuppressWarnings("deprecation")
        @Override

Try this code, it works fine for me:

//Creating xml file

I hope it will work

// the file to be posted
String textFile = Environment.getExternalStorageDirectory() + "/sample.txt";
 Log.v(TAG, "textFile: " + textFile);

 // the URL where the file will be posted
 String postReceiverUrl = "http://yourdomain.com/post_data_receiver.php";
Log.v(TAG, "postURL: " + postReceiverUrl);

 // new HttpClient
 HttpClient httpClient = new DefaultHttpClient();

// post header
HttpPost httpPost = new HttpPost(postReceiverUrl);

File file = new File(textFile);
FileBody fileBody = new FileBody(file);

MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
reqEntity.addPart("file", fileBody);
httpPost.setEntity(reqEntity);

// execute HTTP post request
HttpResponse response = httpClient.execute(httpPost);
HttpEntity resEntity = response.getEntity();

if (resEntity != null) {

String responseStr = EntityUtils.toString(resEntity).trim();
Log.v(TAG, "Response: " +  responseStr);

// you can add an if statement here and do other actions based on the response
}

and php code.
<?php
// if text data was posted
if($_POST){
print_r($_POST);
}

 // if a file was posted
 else if($_FILES){
 $file = $_FILES['file'];
 $fileContents = file_get_contents($file["tmp_name"]);
 print_r($fileContents);
 }
 ?>

Try this code:

HttpURLConnection connection = null;

DataInputStream inputStream = null;

String pathToOurFile = "/data/file_to_send.mp3";
String urlServer = "http://192.168.1.1/handle_upload.php";
String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary =  "*****";

int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1*1024*1024;

try
{
FileInputStream fileInputStream = new FileInputStream(new File(pathToOurFile) );

URL url = new URL(urlServer);
connection = (HttpURLConnection) url.openConnection();

// Allow Inputs & Outputs
connection.setDoInput(true);
connection.setDoOutput(true);
connection.setUseCaches(false);

// Enable POST method
connection.setRequestMethod("POST");

connection.setRequestProperty("Connection", "Keep-Alive");
connection.setRequestProperty("Content-Type", "multipart/form-data;boundary="+boundary);

outputStream = new DataOutputStream( connection.getOutputStream() );
outputStream.writeBytes(twoHyphens + boundary + lineEnd);
outputStream.writeBytes("Content-Disposition: form-data; name=\"uploadedfile\";filename=\"" + pathToOurFile +"\"" + lineEnd);
outputStream.writeBytes(lineEnd);

bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
buffer = new byte[bufferSize];

// Read file
bytesRead = fileInputStream.read(buffer, 0, bufferSize);

while (bytesRead > 0)

outputStream.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);

// Responses from the server (code and message)
serverResponseCode = connection.getResponseCode();
serverResponseMessage = connection.getResponseMessage();

fileInputStream.close();
outputStream.flush();
outputStream.close();
}
catch (Exception ex)

//Exception handling
}

you can add this as NameValuePair

String xmlContent=getStringFromFile();//your method here
    List<NameValuePair> nvps = new ArrayList<NameValuePair>();
        nvps.add(new BasicNameValuePair("xmlData",
                        xmlContent));

and send as

HttpPost httppost = new HttpPost(url);

httppost.setEntity(new UrlEncodedFormEntity(nvps, HTTP.ISO_8859_1));

OR If you want to send as a file you need to use the multi-part Ref Here:
