SDK Internationalization

Set up the locale in the CheckoutSettings and start the CheckoutActivity. For example:

CheckoutSettings checkoutSettings = new CheckoutSettings(checkoutId, paymentBrands);
checkoutSettings.setLocale("de_DE");

Intent intent = new Intent(YOURACTIVITY.this, CheckoutActivity.class);
intent.putExtra(CheckoutActivity.CHECKOUT_SETTINGS, checkoutSettings);

startActivityForResult(intent, CheckoutActivity.CHECKOUT_ACTIVITY);

You can simply override string resources by adding the string with the same key to your app res/values/strings.xml file.
You will find full list of localizable strings at the end of this guide.

<string name="checkout_transaction_run">Please wait</string>
<string name="checkout_payment_details">Payment Details</string>
<string name="checkout_processing">Processing</string>
....

Add a new language for checkout by creating a new folder for translation values with appropriate locale in /res/ folder. For example see the French language folder: /res/values-fr/.

Add default strings.xml there. It can be found in the default folder: /res/values/

You can localize label for any payment method you need. Just add a translation with an appropriate key which is brand constant in lowercase, e.g. master.

<string name="master">MasterCard</string>
<string name="amex">American Express</string>
