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);
}
}
}
Localization
Drop-In is currently localized for 23 languages. To view localized text for a specific locale, open its corresponding values-<LOCALE_NAME>/strings.xml resource file.
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
}
}
});
