Hey @kimrtaylor thanks for using the Braintree SDK for Android. I'd like to help pinpoint the issue and hopefully find a fix.

One thing that seems odd to me is the stack trace mentions the exception originating form TLSCertificatePinning.java in our SDK. TLSCetificatePinning in our project is written in Kotlin.

Can you help me to answer a few questions:

• Have you been able to reproduce the issue?
• Is your app native Android or React Native?
• Is there any additional information you can provide about the devices that experience this issue (e.g. Android version, Device Manufacturer / Model)?

Hey @kimrtaylor @nick-titov-sw checking in. Is there any additional information available for this crash?

Hey @sshropshire, thanks for such a quick response! We are not able to reproduce the issue ourselves, most of the crashes happened on Samsung devicese and the rest on Oppo and Google Pixel, Android versions 13 and 14. Its a native Android application. Thanks a lot for checking!

Thanks @nick-titov-sw. It's interesting the portion of the code that throws the NPE is virtually the same for TLSCertificatePinning.kt in v4.44.0. We did update the SDK's pinned certificates, but we only changed the string contents of the CERTIFICATES property. Does your app have any similar crashes with the 4.44.0 version?

[nick-titov-sw]

@sshropshire seems like we never had it before, it's a new one for 4.45.0.

@nick-titov-sw going to try this to see if it helps resolve: https://github.com/braintree/braintree_android/pull/1036.
