Sending a xml file to a web service in android

Question

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.

Post the code on the server side to receive the file. – vzamanillo Feb 06 '14 at 11:25 — vzamanillo, Feb 06 '14 at 11:25

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:

where to add "List nvps = new ArrayList(); nvps.add(new BasicNameValuePair("xmlData", "xmlCOntent"));" in my particular code? – D'yer Mak'er Jan 31 '14 at 06:22
you can add any where before HttpPost method. – Padma Kumar Jan 31 '14 at 06:30

Try this code:

HttpURLConnection connection = null;
DataOutputStream outputStream = 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.write(buffer, 0, bufferSize);
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
}

outputStream.writeBytes(lineEnd);
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

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 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 ...");
