Initialization

Initialize the SDK in your Application class:

import com.metric.fingerprint.ui.*
import com.metric.fingerprint.core.*

class MyApplication : Application() {
    override fun onCreate() {
        super.onCreate()
        
        // Initialize UI SDK (also initializes core SDK)
        MetricFingerprint.init(
            context = this,
            theme = FingerprintTheme(
                companyName = "Your Company Name",
                logo = Logo.Url("https://example.com/logo.png"),
                color = "#f7cd46"
            ),
            clientKey = "your-client-key",
            secretKey = "your-secret-key",
            environment = Environment.PROD
        )
    }
}

Alternative Authentication Methods

1. Access Authenticator

MetricFingerprint.init(
    context = this,
    theme = FingerprintTheme(...),
    authenticator = { AccessAuthenticator(
        accessToken = "your-access-token",
        accessSignature = "your-signature"
    ) },
    environment = Environment.PROD
)

2. Lazy Authenticator (for dynamic credentials):

MetricFingerprint.init(
    context = this,
    theme = FingerprintTheme(...),
    authenticator = { 
        // Fetch credentials dynamically
        val credentials = fetchCredentials()
        ClientAuthenticator(credentials.clientKey, credentials.secretKey)
    },
    environment = Environment.PROD
)
