Android Question

How do I integrate the ATOM payment gateway in my app?

I am new to Android.

I want to know how can I integrate the ATOM payment gateway mobile checkout page in my application?

I want it so that the user should fill his credit card details and pay on-line.

If I use other payment gateways, like Paytm or Payu they provide an SDK, but Atom doesn't

Any help would be appreciated

As we know ATOM Dosen't Provide SDK After many resarch i had found solution

Call this asynctask in button click

private class StartPayment extends AsyncTask<String, Void, String> {
    String Atom2Request;

    protected String doInBackground(String... params) {
        SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
        String CurrDateTime = sdf.format(new Date()).toString();
            vVenderURL = "https://paynetzuat.atomtech.in/paynetz/epi/fts?login=160&pass=Test@123&ttype=NBFundTransfer&prodid=NSE&amt=50&txncurr=INR&txnscamt=0&clientcode=TkFWSU4%3d&txnid=123&date=03/07/2015&custacc=1234567890&udf1=Customer&udf2=rajtufan@gmail.com&udf3=8485835654&udf4=pune&ru=http://example.webservice/response.aspx?";

        Log.d("Vvendor URL", vVenderURL);
        XMLParser parser = new XMLParser();
        String xml = parser.getXmlFromUrl(vVenderURL); // getting XML
        Document doc = parser.getXMLElement(xml); // getting DOM element
        Log.d("XML URL", xml);
        NodeList nList = doc.getElementsByTagName(KEY_RESPONSE);

        for (int tempN = 0; tempN < nList.getLength(); tempN++) {
            Node nNode = nList.item(tempN);
            if (nNode.getNodeType() == Node.ELEMENT_NODE) {
                Element eElement = (Element) nNode;
                System.out.println("URL : " + eElement.getElementsByTagName("url").item(0).getChildNodes().item(0).getNodeValue());
                xmlURL = eElement.getElementsByTagName("url").item(0).getChildNodes().item(0).getNodeValue();

                NodeList aList = eElement.getElementsByTagName("param");
                String vParamName;
                for (int atrCnt = 0; atrCnt < aList.getLength(); atrCnt++) {
                    vParamName = aList.item(atrCnt).getAttributes().getNamedItem("name").getNodeValue();
                    System.out.println("<br>paramName : : " + vParamName);

                    if (vParamName.equals("ttype")) {
                        xmlttype = aList.item(atrCnt).getChildNodes().item(0).getNodeValue();
                    } else if (vParamName.equals("tempTxnId")) {
                        xmltempTxnId = aList.item(atrCnt).getChildNodes().item(0).getNodeValue();
                    } else if (vParamName.equals("token")) {
                        xmltoken = aList.item(atrCnt).getChildNodes().item(0).getNodeValue();
                    } else if (vParamName.equals("txnStage")) {
                        xmltxnStage = aList.item(atrCnt).getChildNodes().item(0).getNodeValue();
                Log.d("XML URL", xmlURL);
                Log.d("XML TRANS TYPE", xmlttype);
                Log.d("tempTxnId : ", xmltempTxnId);
                Log.d("param : token     :", xmltoken);
                Log.d("param : txnStage  : ", xmltxnStage);

        Atom2Request = xmlURL + "?ttype=" + xmlttype + "&tempTxnId=" + xmltempTxnId + "&token=" + xmltoken + "&txnStage=" + xmltxnStage;
        Atom2Request = Atom2Request.replace(" ", "%20");
        Log.d("ATOM 2nd Request URl", Atom2Request);

        return Atom2Request;

    protected void onPostExecute(String result) {
        if (pDialog != null) {
            Intent intent = new Intent(Recharge_Activity.this, WebContent.class);
            intent.putExtra(KEY_ATOM2REQUEST, result);
            startActivityForResult(intent, 3);


    protected void onPreExecute() {
        pDialog.setMessage("Processing Request...");


when we got response from web page we have form a url and transfer to


 import android.app.Activity;

  static Context mContext;
  public static final String KEY_ATOM2REQUEST = "Atom2Request";
  String Atom2Request;

boolean loadingFinished = true;
boolean redirect = false;

protected void onCreate(Bundle savedInstanceState) {
  //  Thread.setDefaultUncaughtExceptionHandler(new ExceptionHandler(this));
    mContext = this;
    Bundle extras = getIntent().getExtras();
    if (extras != null)
        Atom2Request = extras.getString(KEY_ATOM2REQUEST);
    Log.d("ATOM2Request webview", Atom2Request);
    WebView webView = (WebView) findViewById(R.id.webView);
    webView.setWebViewClient(new MyWebViewClient());
    webView.addJavascriptInterface(new WebAppInterface(this), "Android");


private class MyWebViewClient extends WebViewClient {
    public boolean shouldOverrideUrlLoading(WebView view, String urlNewString) {
        if (!loadingFinished) {
            redirect = true;

        loadingFinished = false;
        return true;

    public void onPageStarted(WebView view, String url, Bitmap facIcon) {

        Log.w(TAG, "Loading");

        if (loadingFinished && !redirect) {
            Log.w(TAG, "Finish Loading");
        } else {
            redirect = false;

public class WebAppInterface {
    Context mContext;
    WebAppInterface(Context c) {
        mContext = c;
    public void onResponse(String reponseText) {
        Intent returnIntent = new Intent();
        returnIntent.putExtra("Result", reponseText);
        setResult(RESULT_OK, returnIntent);



//in vVendorURl you need a redirect url to fetch request from ATOM and send response to android Mobile

Just put this code inside redirect url

//reponseText is text recevied frm ATOM that is Okay or No

in vVendorUrl you have to pass a return url..make a page in server ..and put this java script code inside url.

<script type="text/javascript">
 function showAndroidToast(reponseText) {
