🚀 Selendroid Architecture Overview

Selendroid Tutorial for Beginners: Selendroid consists of four main components:

1. WebDriver Client – Based on Selenium Java Client API.
   
2. Selendroid-Server – Embedded in the app under test.
   
3. Android Driver App – Tests web view content in mobile browsers.
   
4. Selendroid-Standalone – Handles server setup and app installation.
   

Selendroid relies on Android’s Instrumentation framework and Selenium’s WebDriver API for seamless integration.
