how do we get to know Users Android device MTU size ?

[preethiEshwar]

We have our application in Xamarin forms for android devices how do we get to know the MTU size of the android device which user is using ?

I should be notify user if users device MTU size is not supported to use our application must check the MTU size of user device first.
Also is there a way to notify user before installing application from playstore? or before showing launch screen in the application.
