You are helping me integrate my Android ePOS application with Teya card machines using the
Teya Unified ePOS SDK (POSLink: my ePOS and the Teya card machine are separate devices).

My stack: [describe your app language/framework, e.g. Kotlin/Jetpack Compose]

Key facts:
- Add the SDK from Maven Central: implementation("com.teya.epos:unified-sdk:<version>")
  in build.gradle(.kts), with mavenCentral() in settings.gradle(.kts) repositories.
- Requirements: take the minimum supported minSdkVersion, compileSdkVersion, Android Gradle
  Plugin, Gradle and Kotlin versions from the requirements table on
  https://docs.teya.com/epos-sdk/poslink/android/getting-started - do not guess them, and do
  not rely on versions you may remember, as they change with each SDK release.
- I need a Client ID and Client Secret from the Teya Developer Portal (partner.teya.xyz for
  development, partner.teya.com for production). This is one set for my whole application,
  not one per merchant - merchants authenticate separately with their own Teya ID.
- Initialize the SDK with:
  val teyaPosLinkSDK = TeyaPosLinkSDK(
      isProductionEnv = false,
      authConfig = PosLinkSDK.AuthConfig.Managed(clientId = "...", clientSecret = "..."),
      eposInstanceId = null, // optional identifier for this ePOS instance
      logger = LoggerImpl() // optional, implements the SDK's Logger interface
  )
- Call teyaPosLinkSDK.setup(onFailure, onSuccess) to run the SDK's built-in UI for
  authentication, store selection, and card machine selection. After setup succeeds, use
  teyaPosLinkSDK.transactionsApi and teyaPosLinkSDK.printingApi.
- To make a payment, call teyaPosLinkSDK.transactionsApi.makePayment(transactionId, amount,
  currency, tip). amount and tip are in the smallest currency unit (e.g. cents) and currency
  is an ISO 4217 code (e.g. "GBP"). This returns a PaymentStateSubscription for real-time
  status updates.
- Tips, cancellations, refunds, receipts, and Pay at Table are additional SDK calls with
  real-time responses.

Documentation to follow (read these before writing code):
- https://docs.teya.com/epos-sdk/poslink/android/getting-started
- https://docs.teya.com/epos-sdk/poslink/android/make-payment
- https://docs.teya.com/epos-sdk/overview

Task: add the SDK dependency, implement the Connect to Teya flow via setup(), and implement
a basic make-payment call with result handling. Follow the documentation exactly and do not
invent SDK methods - if unsure of an API name, tell me to check the docs page rather than
guessing.
