Braintree Android Drop-In

Braintree Android Drop-In is a readymade UI that allows you to accept card and alternative payments in your Android app.

Adding it to your project

Add the dependency in your build.gradle:

dependencies {
  implementation 'com.braintreepayments.api:drop-in:5.2.1'
}

To use the latest build from the master branch use:

dependencies {
  implementation 'com.braintreepayments.api:drop-in:5.2.2-SNAPSHOT'
}

Usage

Create a DropInRequest and use the Intent to start Drop-In:

DropInRequest dropInRequest = new DropInRequest()
    .clientToken(mClientToken);
startActivityForResult(dropInRequest.getIntent(context), DROP_IN_REQUEST);

Handle the response:

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == DROP_IN_REQUEST) {
        if (resultCode == RESULT_OK) {
            DropInResult result = data.getParcelableExtra(DropInResult.EXTRA_DROP_IN_RESULT);
            String paymentMethodNonce = result.getPaymentMethodNonce().getNonce();
            // send paymentMethodNonce to your server
        } else if (resultCode == RESULT_CANCELED) {
            // canceled
        } else {
            // an error occurred, checked the returned exception
            Exception exception = (Exception) data.getSerializableExtra(DropInActivity.EXTRA_ERROR);
        }
    }
}

3D Secure + Drop-in

The new Drop-In supports 3D-Secure verification. Assuming you have 3D-Secure configured for your account, enable it in your client with DropInRequest.requestThreeDSecureVerification(true) and set an amount. Then, create a ThreeDSecureRequest() object, setting ThreeDSecurePostalAddress and ThreeDSecureAdditionalInformation fields where possible; the more fields that are set, the less likely a user will be presented with a challenge. For more information, check our 3D Secure Migration Guide. Make sure to attach this object to the BTDropInRequest before use.

ThreeDSecurePostalAddress billingAddress = new ThreeDSecurePostalAddress()
    .givenName("Jill")
    .surname("Doe")
    .phoneNumber("5551234567")
    .streetAddress("555 Smith St")
    .extendedAddress("#2")
    .locality("Chicago")
    .region("IL")
    .postalCode("12345")
    .countryCodeAlpha2("US");

ThreeDSecureRequest threeDSecureRequest = new ThreeDSecureRequest()
    .amount("1.00")
    .versionRequested(ThreeDSecureRequest.VERSION_2)
    .email("[email protected]")
    .mobilePhoneNumber("3125551234")
    .billingAddress(billingAddress)
    .additionalInformation(additionalInformation);


// Optional additional information.
// For best results, provide as many of these elements as possible.
ThreeDSecureAdditionalInformation additionalInformation = new ThreeDSecureAdditionalInformation()
    .accountId("account-id");

DropInRequest dropInRequest = new DropInRequest()
    .clientToken(mAuthorization)
    .requestThreeDSecureVerification(true)
    .threeDSecureRequest(threedSecureRequest);

Fetch last used payment method

If your user already has an existing payment method, you may not need to show Drop-In. You can check if they have an existing payment method using DropInResult#fetchDropInResult. Note that a payment method will only be returned when using a client token created with a customer_id.

DropInResult.fetchDropInResult(activity, clientToken, new DropInResult.DropInResultListener() {
    @Override
    public void onError(Exception exception) {
        // an error occurred
    }

    @Override
    public void onResult(DropInResult result) {
        if (result.getPaymentMethodType() != null) {
            // use the icon and name to show in your UI
            int icon = result.getPaymentMethodType().getDrawable();
            int name = result.getPaymentMethodType().getLocalizedName();

            if (result.getPaymentMethodType() == PaymentMethodType.GOOGLE_PAY) {
                // The last payment method the user used was GooglePayment. The GooglePayment
                // flow will need to be performed by the user again at the time of checkout
                // using GooglePayment#requestPayment(...). No PaymentMethodNonce will be
                // present in result.getPaymentMethodNonce(), this is only an indication that
                // the user last used GooglePayment.
            } else {
                // show the payment method in your UI and charge the user at the
                // time of checkout using the nonce: paymentMethod.getNonce()
                PaymentMethodNonce paymentMethod = result.getPaymentMethodNonce();
            }
        } else {
            // there was no existing payment method
        }
    }
});
