How Server module works

• When client(test script) requests to create a new AndroidDriver instance with automationName as UIAutomator2, server modules apks will be installed in the corresponding Device/Emulator by appium-uiautomator2-driver.
  1. appium-uiautomator2-server-vx.x.x.APK responsible for executing handlers.
  2. appium-uiautomator2-server-debug-androidTest.apk contains a single test to start the server.

• AppiumServlet is responsible for handling and responding to requests by redirecting request to corresponding handler.
• Handlers will request UIAutomator v2 to perform corresponding action and status of handler will be captured in AppiumResponse.
• Captured AppiumResponse will be returned to appium.
