## Description

This library provides a secure communication bridge for Android applications, enabling interaction between native Java code and web-based JavaScript interfaces within a WebView. It facilitates the invocation of native system methods from web scripts and manages the exchange of data across the language boundary.

The framework utilizes a prompt-based interception layer to validate method signatures before execution, ensuring that only authorized native code is triggered. It supports complex data exchange through structured serialization and provides a mechanism for mapping native methods to web interfaces, allowing for dynamic execution via runtime inspection.

The system handles asynchronous operations by maintaining a registry of web-side function references. This allows native background tasks to trigger specific JavaScript callbacks upon completion, supporting integrated workflows in hybrid mobile applications.
