Fingerprint

[Maksym]

Hi. I'm trying to integrate VisaCheckout SDK to my app. Payment on test environment works well, but if I check `fingerprint` checkbox while signing in, I've got this internal crash.

VisaCheckoutAndroidSdk-5.5.2

Android 8.1.0

Android gradle plugin 3.1.2

Android buildtools 27.0.3

 PS. The manifest contains FINGERPRINT permissons. Also, there is a code which checks figerprint auth is set up and it seems fingerprint is available to use:

private fun initFingerPrint() {
        if (Build.VERSION.SDK_INT < Build.VERSION_CODES.M) {
            Log.d("###", "This Android version does not support fingerprint authentication.")
        }

        val keyguardManager: KeyguardManager = getSystemService(KEYGUARD_SERVICE) as KeyguardManager
        val fingerprintManager: FingerprintManager = getSystemService(FINGERPRINT_SERVICE) as FingerprintManager

        if (!keyguardManager.isKeyguardSecure) {
            Log.d("###", "User hasn't enabled Lock Screen")
        }

        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.USE_FINGERPRINT) != PackageManager.PERMISSION_GRANTED) {
            Log.d("###", "User hasn't granted permission to use Fingerprint")
            return
        }

        if (!fingerprintManager.hasEnrolledFingerprints()) {
            Log.d("###", "User hasn't registered any fingerprints")
            return
        }
        Log.d("###", "Fingerprint authentication is set.\n")
    }

PPS. SDK initialization and usage code:

package dv.pay.app.ui.visa

import com.visa.checkout.Environment
import com.visa.checkout.Profile
import com.visa.checkout.PurchaseInfo
import java.math.BigDecimal

const val API_KEY = "BI0Z97V54UI244BTEICX21RzaaHSlS4VYjaaGqlwBPMivrDFU"
const val PROFILE = "SYSTEMDEFAULT"

fun createPurchase(): PurchaseInfo = PurchaseInfo
    .PurchaseInfoBuilder(
        BigDecimal("10.23"),
        PurchaseInfo.Currency.USD
    )
//    .setShippingHandling(BigDecimal("0"))
//    .setTax(BigDecimal("0"))
//    .setDiscount(BigDecimal("0"))
//    .setMisc(BigDecimal("0"))
//    .setGiftWrap(BigDecimal("0"))
//    .setDescription("Gift Card Order")
//    .setOrderId("234-SD355-343432")
//    .setReviewMessage("Gift Card Order")
//    .setMerchantRequestId("345345345dsfs434343423234234")
//    .setSourceId("test-source-id")
//    .setPromoCode("test-promo-code")
//    .setShippingAddressRequired(true)
//    .setUserReviewAction(PurchaseInfo.UserReviewAction.PAY)
//    .setThreeDSSetup(true, false)
//    .setCustomData(hashMapOf("key" to "value"))
    .build()

fun createPaymentProfile(): Profile = Profile
    .ProfileBuilder(API_KEY, Environment.SANDBOX)
    .setProfileName(PROFILE)
//    .setDisplayName("DV pay demo")
//    .setMerchantId("123")
//    .setDataLevel(Profile.DataLevel.FULL)
//    .setAcceptCanadianVisaDebit(true)
//    .setEnableTokenization(true)
//    .setCardBrands(cards)
//    .setShippingCountries(shippingCountries)
//    .setBillingCountries(billingCountries)
    .build()

private val cards = arrayOf(
    Profile.CardBrand.VISA,
    Profile.CardBrand.MASTERCARD
)

private val shippingCountries = arrayOf(
    Profile.Country.UA
)

private val billingCountries = arrayOf(
    Profile.Country.UA
)
