[Bug] [Android] CardField onCardChange not triggering in React Native Stripe

[RohanRajGautam]

Describe the bug
The CardField component's onCardChange callback is not triggering when entering card details. No values are being received in the callback function, making it impossible to capture and validate card information.

To Reproduce
Steps to reproduce the behavior:

1. Initialize Stripe in your React Native app
2. Implement CardField component with onCardChange handler
3. Run the app and navigate to the credit card input screen
4. Try entering card details in the field
5. Check console logs - no output is shown
6. Check card state - remains null

Code example:

<CardField
postalCodeEnabled={false}
placeholders={{
number: '1234 1234 1234 1234',
}}
cardStyle={{
backgroundColor: '#FFFFFF',
textColor: '#000000',
}}
style={{
height: 50,
width: '100%',
}}
onCardChange={(cardDetails) => {
console.log('Card Details:', cardDetails);
setCard(cardDetails.complete ? cardDetails : null);
}}
/>

Screenshot

Expected behavior

• onCardChange callback should fire whenever user enters or modifies card details
• Callback should receive CardFieldInput.Details object containing card information
• Console should show logged card details
• Card state should update when details are complete

Smartphone (please complete the following information):

• Device: Android
• React Native Version: 0.76.1
• @stripe/stripe-react-native Version: [^0.39.0]

Additional context

• Component renders correctly and is visible
• No error messages in console
• Other Stripe components working as expected
• Stripe initialization is successful
• Issue occurs on Android only

Possible Workarounds Needed
Looking for either:

1. Correct implementation of CardField with working onCardChange
2. Alternative method to capture card details
3. Any known workarounds for this issue

Same issue, the new architecture is being a huge problem for this library.

Here is a patch that works with fabric enabled app on Android:
