title: How to preserve Appium session between multiple testng class
body: <p>I am automating Android application using Appium, I have One Base Class with Setup and Tear down (In setup initialization appium session and in teardown destroying session ). </p>
  
  <p>This Base Class I inherited in all testng classes, now for each test class Appium new session generated. </p>
  
  <p>So My question is that How we maintain appium session through out the all class once it generate for any class. </p>
  
  <p>Thanks
