Custom Checkout Integration - Android

Learn in detail about our custom checkout integration for android.

The android integration can be completed in three steps and should not take you more than 30 minutes.

Integration Flow

  • Create Order - Create an order in Cashfree Payments system from your backend.
  • Submit the form from your application's web-view as mentioned in this document.
  • Detect the URL redirection and close the web view.


This integration requires your application's package name to be whitelisted by Cashfree Payments. Please check Whitelisting Process

Step 1: Create Order

Please follow the steps mentioned in this link to create an order. This will return a "payment_session_id" value which will be used later.


Don't forget to provide the return URL while creating the order as this will be used to detect payment completion.

Step 2: Pay Order

String platform = "chxx-c-x-x-x-w-x-a-" + android.os.Build.VERSION.SDK_INT;
String paymentSessionID = "PAYMENT_SESSION_ID";
String env = "SANDBOX"; // or "PROD"
String formURL = env.equals("SANBOX")? "" : ""

String htmlForm = "<html>\n" +
                "\n" +
                "<body>\n" +
                "    <form id=\"redirectForm\" method=\"post\" action=\""+formURL+"\"> \n" +
                "        <input\n" +
                "            type=\"hidden\" name=\"payment_session_id\"\n" +
                "            value=\""+paymentSessionID+"\" />\n" +
                "        <input type=\"hidden\" name=\"platform\"\n" +
                "            value=\""+platform+"\" /></form>\n" +
                "    <script\n" +
                "        type=\"text/javascript\">\twindow.onload = function () { const form = document.getElementById(\"redirectForm\"); const meta = { userAgent: window.navigator.userAgent, }; const sortedMeta = Object.entries(meta).sort().reduce((o, [k, v]) => { o[k] = v; return o; }, {}); const base64Meta = btoa(JSON.stringify(sortedMeta)); FN = document.createElement('input'); FN.setAttribute('type', 'hidden'); FN.setAttribute('name', 'browser_meta'); FN.setAttribute('value', base64Meta); form.appendChild(FN); form.submit(); }  </script>\n" +
                "</body>\n" +
                "\n" +

loadDataWithBaseURL("", htmlForm, "text/html",, "");

Step 3: Handle Redirection

Once the payment flow has ended, Cashfree Payments will redirect you to the URL specified while creating the order. Detect the URL redirection and close the web view appropriately.

yourWebView.setWebViewClient(new WebViewClient(){
            public boolean shouldOverrideUrlLoading(WebView view, String url) {
                //Find if the url is the return URL you gave while creating the order 
                // and close the webview
                return super.shouldOverrideUrlLoading(view, url);

UPI Intent from Checkout

If you are doing a custom integration of Cashfree Payments Web Checkout in Android and want to add UPI intent functionality, follow the steps below. Read more about UPI Intent functionality here.

  1. Add the queries element in AndroidManifest file.
  2. Add the JSBridge functions for the checkout page to get the list of UPI apps installed and for opening the UPI app selected by the user.
  3. Once the user comes back from the UPI app, the onActivityResult function notifies the checkout page by calling a javascript function inside the checkout page.

You need to add the following to your AndroidManifest.xml

<manifest package="">
        <action android:name="android.intent.action.VIEW" />
        <data android:scheme="upi" android:host="pay"/>
    <package android:name="" />
