Android and Compose demo

The Android demo implements Kora Market as a native Material 3 product experience. It asks a merchant backend for a finalized order ID, then presents the Inttegro payment sheet without embedding an API key in the app.

About the app

Kora Market gives shoppers a focused way to discover a product, make their selection, and pay without leaving the Android app. The experience keeps the purchase journey continuous instead of sending the customer through a generic mobile web form.

For the merchant, it brings checkout into a polished native storefront while the backend remains in control of the product and amount being charged. That keeps sensitive commerce decisions off the device without sacrificing the feel of an app-native purchase.

Start with MCP

Connect your MCP client and ask MCP to design the server and native boundaries for your Android checkout. Use the resulting plan to decide what the app may send, what the backend owns, and how payment is verified.

What it demonstrates

  • A Jetpack Compose product screen using Material 3
  • A narrow merchant-backend request that returns only a finalized order ID
  • Native payment-sheet presentation and lifecycle-safe telemetry cleanup
  • Safe immediate UX followed by authoritative server-side payment verification

Run the demo

Install Android Studio, set the demo backend URL, open the project, allow Gradle to sync, and run the app configuration on an emulator or device. The released README contains the exact configuration and assembly check.

Follow the integration

  1. DemoBackend.kt implements the mobile-to-merchant-backend trust boundary.
  2. MainActivity.kt presents the payment sheet and handles telemetry and result semantics.

Production boundary

Authenticate the request to your merchant backend and determine the customer, product, price, currency, and allowed payment methods there. The app receives an order ID, not an Inttegro API key, and fulfillment waits for server-side verification.
