Hey @hankyjcheng thanks for using the Braintree SDK for Android and for filing this. Do you have any additional information about the environment in which the crash occurred e.g. Device Name, Device Manufacturer etc.?

[hankyjcheng]

@sshropshire yeah it's happening on different major manufacturers like Samsung and Google. Here is a screen shot we have on Firebase Crashlytics. As you can see 96% occurred on Android 14.

Hello,

I got a crash report with the same issue a few days ago.

Using com.braintreepayments.api:drop-in:6.16.0

The crash also occurred on Android 14.

Even in other issues I see java.lang.NullPointerException mostly in Android 14 and it seems some package or plugin being used by Braintree has some issues with Android 14. Because the same things are working fine on Android 13 and Android 15.
