Use the Razorpay Android Standard SDK to integrate supported payment methods on the Checkout form of your Android app as per your business requirements. Here are some additional methods provided by the SDK for the integration and usage of payment methods:

• Card Utilities
• Validate Data
• Custom WebViewClient and WebChromeClient

Card Utilities

You can use these methods for card payment method integration.

• Fetch card network
• Validate card number
• Fetch card number length of a card network

Fetch Card Network

The SDK provides a method to get the card network name of the provided card number.

• At least 6 digits of the card number are required to identify the network.
  
• Possible values returned by this method are visa, mastercard and unknown.
  
• If it is not able to identify the network it returns unknown.

Fetch Card Network

razorpay.getCardNetwork(cardNumber);

Validate Card Number

You can determine the validity of the card number entered using the isValidCardNumber method. This is a checksum-based method to determine if the entered card number is valid or not.

Card Number Validation

razorpay.isValidCardNumber(cardNumber);

Fetch Card Number Length for Card Network

You can fetch the length of a card number for a specific card network using the getCardNetworkLength method.

Fetch Length for Card Network

razorpay.getCardNetworkLength(cardNetworkName);

Data Validation

The SDK provides basic validation for the payment data JSONObject. In case of a validation error, the SDK returns an error map in the onValidationError callback function.

Sample Code

The sample code shown below describes a validation error on the contact field:

Data Validation

razorpay.validateFields(payload, new Razorpay.ValidationListener() {
	@Override
	public void onValidationSuccess() {
		try {
		  razorpay.submit(payload);
		} catch (Exception exception){}
	}

	@Override
	public void onValidationError(Map<String, String> error) {
		/**
		 * The format for returned map is:
		 *   "field" : "contact"
		 *   "description" : "Descriptive error message"
		 */
		Toast.makeText(activity, "Validation: " + error.get("field") + " " + error.get("description"), Toast.LENGTH_SHORT).show();
	}
});

Custom WebViewClient and WebChromeClient

Our SDK sets an instance of RazorpayWebViewClient and RazorpayWebChromeClient to the Webview passed to facilitate bank page optimizations. If you want to set your own custom WebViewClient you have to extend RazorpayWebViewClient and pass it to our SDK.

Watch Out!

This step is optional and is only required when you want to set a custom WebViewClient/WebChromeClient

Sample Code

The sample code given below shows how to customize the RazorpayWebViewClient:

Customize RazorpayWebViewClient

/**
 * Extend the RazorpayWebViewClient for your custom hooks
 */
razorpay.setWebviewClient(new RazorpayWebViewClient(razorpay){

  @Override
  public void onPageStarted(WebView view, String url, Bitmap favicon) {
      // Make sure you do not forget to call the super method
      super.onPageStarted(view, url, favicon);
      Log.d(TAG, "Custom client onPageStarted");
  }

  @Override
  public void onPageFinished(WebView view, String url) {
      // Make sure you do not forget to call the super method
      super.onPageFinished(view, url);
      Log.d(TAG, "Custom client onPageFinished");
  }
});

Similarly, you can set your own WebChromeClient:

Set WebChromeClient

/**
 * Extend the RazorpayWebChromeClient for your custom hooks
 */
razorpay.setWebChromeClient(new RazorpayWebChromeClient() {
	@Override
	public void onProgressChanged(WebView view, int newProgress) {
		// Make sure you do not forget to call the super method
		super.onProgressChanged(view, newProgress);
		customProgressBar.setProgress(newProgress);
	}
});
