App Onboarding — Android

One-time device registration required before the first transaction:

sdk.onboardDevice(
    merchantID = "YOUR_MERCHANT_ID",
    onSuccess = { enablePaymentUI() },
    onError = { error -> Log.e("CyoGate", error.message ?: "Failed") }
)

Onboarding is cached — only required once per device installation. Re-onboarding needed if app data is cleared.
