Google Pay APIで取得したPayment tokenの指定方法(Android版)
1.Payment tokenを取得する
PaymentToken取得プログラム (Google Pay developersサイトより抜粋)
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (requestCode) {
case LOAD_PAYMENT_DATA_REQUEST_CODE:
switch (resultCode) {
case Activity.RESULT_OK:
PaymentData paymentData = PaymentData.getFromIntent(data);
String token = paymentData.getPaymentMethodToken().getToken();
break;
case Activity.RESULT_CANCELED:
break;
case AutoResolveHelper.RESULT_ERROR:
Status status = AutoResolveHelper.getStatusFromIntent(data);
// Log the status for debugging.
// Generally, there is no need to show an error to
// the user as the Google Pay API will do that.
break;
default:
// Do nothing.
}
break;
default:
// Do nothing.
}
