Collect card data from your UI to construct a CardBuilder. You can then call tokenize to get a nonce that can be sent to your server:

CardBuilder cardBuilder = new CardBuilder()
  .cardNumber("4111111111111111")
  .expirationDate("09/2018");

Card.tokenize(mBraintreeFragment, cardBuilder);

You'll need to register a listener to receive a payment method nonce once the card tokenization finishes.
