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

Question

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

Answer 1

According to this,no java and/or android SDK is provided by them. You can still click the "contact us" button(in the bottom of the webpage) and ask them directly weather they provide any SDK for java/android or not.

Update: Android SDK is now provided by ATOM Payment gateway.Click this to get the same.

Call this asynctask on Payment button click

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

    @Override
    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&[email protected]&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();

                    }
                }
                Log.d("XML URL", xmlURL);

                Log.d("param : txnStage  : ", xmltxnStage);
            }
        }//for

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


        return Atom2Request;
    }

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

    }

    @Override
    protected void onPreExecute() {
        pDialog.setMessage("Processing Request...");
        pDialog.setIndeterminate(false);
        pDialog.setCancelable(false);
        pDialog.show();
        super.onPreExecute();
    }


}

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

WebContent.class

 import android.app.Activity;
 import android.content.Context;
 import android.content.Intent;
 import android.content.SharedPreferences;
 import android.graphics.Bitmap;
 import android.os.Bundle;
 import android.util.Log;
 import android.webkit.JavascriptInterface;
 import android.webkit.WebView;
 import android.webkit.WebViewClient;



 public class WebContent extends Activity {
  private static final String TAG = "WebContent";
  SharedPreferences sp;
  static Context mContext;
  public static final String KEY_ATOM2REQUEST = "Atom2Request";
  String Atom2Request;
Intent intent;
boolean loadingFinished = true;
boolean redirect = false;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.webviewrecharge);
  //  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.getSettings().setJavaScriptEnabled(true);
    webView.getSettings().setDomStorageEnabled(true);
    webView.addJavascriptInterface(new WebAppInterface(this), "Android");

    webView.loadUrl(Atom2Request);
}

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

        loadingFinished = false;
        view.loadUrl(urlNewString);
        return true;
    }

    @Override
    public void onPageStarted(WebView view, String url, Bitmap facIcon) {
        loadingFinished = false;
        //SHOW LOADING IF IT ISNT ALREADY VISIBLE
        Log.w(TAG, "Loading");
    }

    @Override
    public void onPageFinished(WebView view, String url) {
        if (!redirect) {
            loadingFinished = true;
        }

        if (loadingFinished && !redirect) {
            //HIDE LOADING IT HAS FINISHED
            Log.w(TAG, "Finish Loading");
        } else {
            redirect = false;
        }

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

    }
}

}

//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) {
 Android.onResponse(reponseText);
 }
