Hi @Jake-Jiangת Thank you for reaching out to us.

Please make sure that you added the following keep rule:

-keep class com.appsflyer.** { *; }

Also, make sure that your generated SDK is not missing our resources files. If the issue persists, we would kindly ask you to submit a support ticket to support@appsflyer.com to provide optimal support.

When submitting the ticket, please specify your AppsFlyer sign-up (account) email, app ID, reproduction steps, code snippets, logs, the links you used, and any additional relevant information.

Hi @pazlavi ，Thanks for the quick reply, I confirm it has been added the following keep rule:

-keep class com.appsflyer.* { ; }

Also, I make sure that the generated SDK is not missing our resources files.

I found the reason may be upgrade the Braintree SDK, if I don't upgrade Braintree SDK, AppsFlyer works normally, I am more puzzled why upgrading the Braintree SDK will affect AppsFlyer

I also have the following line in the rules: -keep class com.appsflyer.** { *; }

And I do not have the Braintree SDK. The AppsFlyer SDK version I'm using is 6.3.2

[pazlavi]

@rodrigoarias , Please update to the latest SDK version

[rodrigoarias]

Thanks @pazlavi, version 6.9.2 seems to fix the problem.
