Custom Chromium-Based Web Browser for Android App

I need a custom web browser integrated into my existing Android app. The browser should be Chromium-based (or any alternative that’s easy to maintain, but not a WebView).

Requirements:
- Must include navigation buttons (back, forward, refresh)
- Complete project source code is required for integration

Ideal Skills and Experience:
- Proficiency in Android development
- Experience with Chromium and custom browser implementations
- Strong understanding of Android app integration and maintenance
