Application Crash when validating payment

[ThomasLaTournee]

We noticed a (rather) small percentage of application crash on our user base on the payment sheet.
After some digging, we can reduce the problem to the following situation:

Platform

• Web
• iOS
• Android

Describe the bug

When returning to the app after it’s been backgrounded (or killed by the system), the Stripe Capacitor plugin’s PluginCall reference is lost. This causes a NullPointerException in PaymentSheetExecutor.onPaymentSheetResult, because the plugin attempts to call currentCall.resolve(...) on a null reference.

To Reproduce
Steps to reproduce the behavior:

0.	In Android Developer Options, enable “Don’t keep activities”. [This allows us to easily reproduce the problem that can only occurs in some edge case (low memory phones, etc..]
1.	Integrate @capacitor-community/stripe v7.2.0 in a Capacitor 7 app
2.	Launch a PaymentSheet (loadPaymentSheet() + presentPaymentSheet()), typically in the 3Dsecure screen waiting for 3DS input
3.	Press Home (or otherwise background the app) while the sheet is still open, go to another app
4.	Return to the app via the task switcher.
5.	Complete or cancel the PaymentSheet flow.
6.	Observe a crash in Logcat:

Caused by java.lang.NullPointerException: Attempt to invoke virtual method  
'void com.getcapacitor.PluginCall.resolve(...)' on a null object reference  
    at com.getcapacitor.community.stripe.paymentsheet.PaymentSheetExecutor.onPaymentSheetResult(...)

Expected behavior
No crash : a way to recover / recreate the activity

Additional context

• tested and reproduced on several android releases (12, 13, 14, 15) and multiple phones.

@ThomasLaTournee anyone responding to these issues?

[ThomasLaTournee]

@snolan-ethika nope, not yet. Do you observe the same behaviour on your application ? It may be useful to complete with other analysis, perhaps in some different context.

@ThomasLaTournee I was asking because I had an issue as well, but finally figured it out. I was curious about the response time since you asked this in July and have heard nothing back. The lack of communication on other issues as well makes me feel like this is almost abandoned?
