I have done Perfectly :) :) You have to edit SuccessURL and FailureURL:

Its Working for Me Perfectly.

public class PayUMoneyActivity extends AppCompatActivity {

    /**

    WebView webView;

What is SuccessURL and failureURL. Could you please help me ? — Manu, Mar 13 '16 at 05:17
You just have to put some web url which will use in `onPageFinished` — Pratik Butani, Jul 08 '16 at 02:48

Hi,I am use some www.success..php and same as failur thay both work on test mode,and also have entry my PayUMoeny Account.but same code in live mode not working.have any change in test mode and live mode?? — Bhoomika Prajapati, Apr 16 '18 at 05:48
@bhoomika what you are getting as error in live mode? Any error? — Pratik Butani, Apr 16 '18 at 05:52
@PratikButani Everything is working fine but how i do I get another full response , and what is the use of PayUJavaScriptInterface , its never triggered — Nirav Joshi, May 25 '18 at 13:56
Is that secure hard coding merchant key ,salt etc in android ?. — sreekanth balu, Dec 20 '19 at 06:49
@PratikButani for testing its okay . But for production I think its recommended to keep salt , key on remote web server and generate hash to use it to post to payumoney . — sreekanth balu, Dec 20 '19 at 07:29

Build Custom Integration

As per payumoney: If you are building your website from scratch you need to make a post request to our API. Pass your key and other mandatory variable. This also include the Success and Failure page URL, where you wish to take your user on success and failure cases.

Step 1: Create a store with any of our e-commerce platform partners.

Step 2: Choose PayUMoney as Payment option.

Step 3: Enter PayUMoney credentials and you are ready to go.

Note: You need to develop your own web services which take data from your client application and forward the request to payumoney server then take responses of callback after that your web services will notify you with result.

FlipKart, FreeCharge, Snapdeal etc they have their own url who will take responsibility to initiate the payment gateway,

So conclusion is that you need to support from your server team to initiate the payment and return the result back to your client application.

You can find the more information about payumoney and api payumoney integration,

Simplest way to integrate Payment gateway is to use a webview for your application.

You can see that most of the applications like FlipKart, FreeCharge, Snapdeal etc., use the same

I know that but sorry, but I don't know how to use a webview for application. Can you please provide some link or sample code to do so? – gautamprajapati Apr 29 '15 at 04:42

STEP 1 Complete a successful test transaction using the test credit card on PayU’s test server. Merchant ID: gtKFFx SALT: eCwWELxi PayU Test URL: https://test.payu.in/_payment Below are the test card details for doing a test transaction in the testing mode Card Name – Any name Card Number: 5123456789012346 CVV: 123 Expiry: may 2017 STEP 2 Once you have done the test transaction successfully. Merchant Key: XYZ SALT: go to --> https://www.payu.in/index?returnUrl=salt# The production URL is: https://secure.payu.in/_payment For Integration Kit: https://github.com/payu-india – Jaydeep Goswami Apr 29 '15 at 04:50

@JaydeepGoswami Can you please explain in more detail that how to send data & which data to web view TEST TRANSACTION url? – VVB Jun 25 '15 at 05:06
Sorry for late reply.. – Jaydeep Goswami Jul 10 '15 at 05:58
As i said you.. First of all download the Library Files from http://github.com/payu-india and – Jaydeep Goswami Jul 10 '15 at 05:59
There you'll find one Documentation File in .pdf format and one library file which you need to include in the file from where you are calling your payment gateway. After that simply call the method specified in the documentation along with the necessary parameters to be passed – Jaydeep Goswami Jul 10 '15 at 06:01
in android native you can JSON Encode your data (i.e., Parameters) and send it to the server script ( .php or .asp file) – Jaydeep Goswami Jul 10 '15 at 06:02

        @Override
        public void onPageFinished(WebView view, String url) {

            if (webViewPreviousState == PAGE_STARTED) {
                dialog.dismiss();
                dialog = null;

            }

        }
    }

    /** The btn back. */
    Button btnBack;

    /** The webview. */
    WebView webview;

    /* (non-Javadoc)
     * @see android.support.v4.app.Fragment#onCreateView(android.view.LayoutInflater, android.view.ViewGroup, android.os.Bundle)
     */
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.payumoney_fragment, container,
                false);


        webview = (WebView) rootView.findViewById(R.id.payu_webview);
        webview.setWebViewClient(new MyWebViewClient());
        webview.getSettings().setDomStorageEnabled(true);
        webview.getSettings().setJavaScriptEnabled(true);
        openURL();

        return rootView;
    }

    /**
     *  Opens the URL in a browser.
     */
    private void openURL() {
        webview.loadUrl(PAYU_MONEY_URL);
        webview.requestFocus();
    }

    public static Fragment newInstance() {
        return new PayYouMoneyFragment();
    }
}

and here is payumoney layout

<?xml version="1.0" encoding="utf-8"?>
<WebView xmlns:android="http://schemas.android.com/apk/res/android"
         android:id="@+id/help_webview"
         android:layout_width="fill_parent"
         android:layout_height="fill_parent"
         android:scrollbars="none"
/>
