Safe Java Js Webview Bridge
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.
Features
- WebView Bi-Directional Interfaces - Provides a secure communication bridge for Android WebView integration in hybrid mobile applications.
- Asynchronous Message-Passing Bridges - Implements a secure message-passing bridge for structured communication between native and web environments.
- Cross-Language Data Exchange - Ensures secure cross-language communication by validating requests and managing data exchange between environments.
- Prompt Interception & Modification - Intercepts communication requests via a prompt mechanism to enforce security and validate method signatures.
- Prompt-Based Interceptors - Validates method signatures through a secure prompt mechanism to prevent unauthorized native code execution.
- Complex Data Serialization - Serializes complex native objects and primitive types for exchange with web-based scripts.
