Step 4: Customize the Checkout Amount
Before trying a credit card transaction, try updating the sample code to change the checkout amount.
./app/src/main/java/com/example/readersdk/CheckoutActivity.javain the sample app.
onCreate()method, change the value of
checkoutAmountfrom 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());
Rebuild the sample app.
Tap the "Charge $2.00" button to complete a new cash transaction.
