Example: Basic Integration

1. Application.kt

class MyApp : Application() {
    override fun onCreate() {
        super.onCreate()
        MetricFingerprint.init(
            context = this,
            theme = FingerprintTheme(
                companyName = "My Company",
                logo = Logo.Url("https://example.com/logo.png"),
                color = "#f7cd46"
            ),
            clientKey = "client-key",
            secretKey = "secret-key",
            environment = Environment.PROD
        )
    }
}

2. MainActivity.kt

class MainActivity : ComponentActivity() {
    private val fingerprintLauncher = registerForActivityResult(
        FingerprintAuthContract()
    ) { result ->
        when (result) {
            is FingerprintAuthResult.Success -> {
                Toast.makeText(
                    this,
                    "Verification successful!\nName: ${result.name}\nSUID: ${result.suid}",
                    Toast.LENGTH_LONG
                ).show()
            }
            is FingerprintAuthResult.Error -> {
                Toast.makeText(
                    this,
                    "Verification failed: ${result.message}",
                    Toast.LENGTH_SHORT
                ).show()
            }
            is FingerprintAuthResult.Cancelled -> {
                Toast.makeText(this, "Cancelled", Toast.LENGTH_SHORT).show()
            }
        }
    }
    
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContent {
            MyAppTheme {
                Column {
                    Button(onClick = {
                        // Generate token from your API
                        lifecycleScope.launch {
                            val token = generateToken()
                            launchFingerprintAuth(token)
                        }
                    }) {
                        Text("Start Fingerprint Verification")
                    }
                }
            }
        }
    }
    
    private fun launchFingerprintAuth(token: String) {
        fingerprintLauncher.launch(FingerprintAuthRequest(token = token))
    }
    
    private suspend fun generateToken(): String {
        // Call your API to generate verification token
        return "your-generated-token"
    }
}
