Google Pay Support in Android WebView

The video announces the support of Google Pay within Android WebView, enabling seamless purchases for users through an Android-native experience. Users can leverage device tokens from their Google Wallet, providing high-quality tokens for transactions.

Benefits of Using Google Pay in WebView:

• Seamless purchase experience for users.
• Android-native experience.
• Utilization of device tokens from Google Wallet.
• High-quality tokens for transactions.
• Increased checkout speed.
• Improved user experience.

Steps to Enable Google Pay in Android WebView:

1. Add or Update androidx.webkit Dependency:

   • Add the androidx.webkit dependency to your Android project using your build system (e.g., Gradle).
   • If already using androidx.webkit, ensure the version is 1.14.0 or higher.
   • Example: implementation "androidx.webkit:webkit:1.14.0" (or higher).

2. Testing Environment:

   • Test on a device with Chrome version 137 or higher.
   • Ensure Google Play services version is 25.18.30 or higher.

3. AndroidManifest Configuration:

   • Adjust the AndroidManifest.xml file to allow Chromium-defined actions: PAY, IS_READY_TO_PAY, and UPDATE_PAYMENT_DETAILS.
   • This involves adding intent filters to the relevant activity or service declarations.

4. Enable Payment Request API:

   • Enable the Payment Request API for the WebView using the WebSettingsCompat directive from the androidx.webkit dependency.
   • Use the correct import statement for WebSettingsCompat.
   • Example:

     import androidx.webkit.WebSettingsCompat;
     import androidx.webkit.WebViewFeature;
     
     if (WebViewFeature.isFeatureSupported(WebViewFeature.PAYMENT_REQUEST_API)) {
         WebSettingsCompat.setPaymentRequestEnabled(webView.getSettings(), true);
     }
     

Important Considerations:

• Pay and Wallet Console Approval: Your application needs to be approved in the Pay and Wallet Console before using Google Pay in production.
• Support Team Approval: Await approval from the Google Pay support team.

Technical Terms and Concepts:

• Android WebView: A system component that allows Android apps to display web pages.
• androidx.webkit: A support library providing backward-compatible features for WebView.
• Payment Request API: A web standard that simplifies the checkout process by providing a consistent interface for payment methods.
• AndroidManifest.xml: The configuration file for Android apps, specifying permissions, components, and other metadata.
• WebSettingsCompat: A class in the androidx.webkit library that provides compatibility methods for WebView settings.
• Device Tokens: Cryptographic tokens representing a user's payment credentials stored in Google Wallet.
