I am using braintree api to get add card in app for payments. It works fines and sometimes crashes randomly,
This is my stacktrace,

This is my gradle version, compile 'com.braintreepayments.api:braintree:2.+'
Full disclosure: I work for Braintree.
Are you refreshing the client token every time you go through the checkout process as required? I see that you are only downloading the Braintree token from the server if it is null.
Without having any insight into your CreditCard class or its validateCard method, another possibility may be that the CardBuilder object you are passing into Card.tokenize may not be well-formed.
If you are still having trouble, please reach out to Braintree support for help debugging your integration.
