Android Crash - PayPal RuntimeException: Failure delivering result ResultInfo

[alefl10]

Attempting to use PayPal on Android crashes my Flutter App, and outputs the following console error

As far as I know, this problem usually arises in a plugin when the result of an onActivityResult call is propagated more than once or if the plugin's result handling code is triggered multiple times.

This is NOT affecting iOS.

Hi @alefl10 Have you fixed this problem yet?

[alefl10]

@TuanMai777 no, the error still persists.

@pikaju are there any updates on it?

Try to see if this solve your issue https://github.com/pikaju/flutter-braintree/issues/166

Hey @nicolobozzato! Nope.. that didn't help. I still got the same issue which logged the same error details as included in the description and then crashed the app.

@nicolobozzato @pikaju @claudius-kienle @TuanMai777

The issue must be coming from the methodChannel requestPaypalNonce, as that's what's been executed after calling Braintree.requestPaypalNonce.

/// Requests a PayPal payment method nonce.
///
/// [authorization] must be either a valid client token or a valid tokenization key.
/// [request] should contain all the information necessary for the PayPal request.
///
/// Returns a [Future] that resolves to a [BraintreePaymentMethodNonce] if the user confirmed the request,
/// or `null` if the user canceled the Vault or Checkout flow.
static Future<BraintreePaymentMethodNonce?> requestPaypalNonce(
  String authorization,
  BraintreePayPalRequest request,
) async {
  final result = await _kChannel.invokeMethod('requestPaypalNonce', {
    'authorization': authorization,
    'request': request.toJson(),
  });
  if (result == null) return null;
  return BraintreePaymentMethodNonce.fromJson(result);
}
