Not able to use UIAutomator 2

I am not able to use UIAutomator2

when I set automationName as UiAutomator1 in DesiredCapabilities it works, But when I mention  UiAutomator2 it throws an error:

{
  "udid": "c8bc7843",
  "deviceName": "c8bc7843",
  "platformName": "Android",
  "platformVersion": "7",
  "noReset": true,
  "fullReset": false,
  "automationName": "UiAutomator2",
  "appPackage": "com.makemytrip",
  "appActivity": "com.mmt.travel.app.home.ui.SplashActivity"
}
