For posterity, the exact API to enable PaymentRequest in WebView is
slightly different from the first email:
WebView myWebView = findViewById(R.id.webview);
WebSettings webSettings = myWebView.getSettings();
if (WebViewFeature.isFeatureSupported(WebViewFeature.PAYMENT_REQUEST)) {
WebSettingsCompat.setPaymentRequestEnabled(webSettings, true);
}
WebSettingsCompat is the forward compatibility API for WebSettings in AndroidX
WebKit <https://developer.android.com/jetpack/androidx/releases/webkit>. It
enables new features in WebView that are not yet available in the Android
OS.
