Here's a formatted version for your GitHub README:

store-unity-sdk

The repository contains two projects: a Unity project and an Android project.

Android Project

A native Java library is developed that integrates seamlessly with Unity. The main features include:

1. WebView Support: Incorporates WebView for in-app browsing.
2. JavaScript Interface: Allows interaction between JavaScript and WebView.
3. Google Play Support: Compatible with Google Play services.
4. Payment Provider Integration: Enables integration with various payment providers.
5. Mock Data: Provides mock data if Google Pay isn't configured.

The primary library class can be found here: PaymentActivity.java

Unity Project

The Unity project folder structure:

1. Editor: Contains post-processors that import dependencies necessary for the library.
2. Example: Demonstrates how to use the SDK.
3. Plugins: Houses the native Java library.
4. Prefabs: Contains product prefabs shown before purchase.
5. Resources: Holds a crucial prefab that initializes and activates the SDK automatically.
6. Source: Contains the SDK source code.

Key Features of the Source Folder:

• Initialization: The Command pattern enables asynchronous initialization for simplicity. One line is sufficient:

  await Initialization.PaymentSDKInitializationController.InitializeAsync();

  The SDK will then be ready for use.

• PaymentEvents: An Observer class that allows subscription and callback registration from any part of the code for smooth SDK integration.

• PaymentPopupController: Manages informational popups for products being purchased.

• BaseProduct: Developers can extend BaseProduct while keeping the base API closed, following SOLID principles.

• PaymentSDK: The main SDK class, providing the following:

  1. ShowProductBundle - Displays the product.
  2. StartPurchase - Invokes native library purchase methods.
  3. Flask processing from the native library.

Dependencies

To use the SDK, you must install the Google Play Games Plugin for Unity, as it supports Google Pay.
