Reader SDK: Quick Start

Step 4: Customize the Checkout Amount

Before trying a credit card transaction, try updating the sample code to change the checkout amount.

Java (Android)
  1. Open ./app/src/main/java/com/example/readersdk/CheckoutActivity.java in the sample app.

  2. In the onCreate() method, change the value of checkoutAmount from 1 USD to 2 USD. As with other Square solutions, Reader SDK specifies monetary amounts in the smallest currency unit of the associated currency code, so 2 USD is specified as 200 cents:

    Money checkoutAmount = new Money(200, CurrencyCode.current()); 
    
  3. Rebuild the sample app.

  4. Tap the "Charge $2.00" button to complete a new cash transaction.

  5. View the transaction details in Square Dashboard.
