Showing Alert Dialog With Yes/No Action Button:  

While asking for for permission at run time , user have option to either accept or deny it, so we need to handle both condition in our application. 
It is straight forward when user give the permission but if user deny it we will show some extra info to user because if our app don’t get the permission it required , it may crash or behave differently , that we need to inform to user. so its important to track the interaction of user. 

If user Deny the Permission we will create a new AlertDialog and Display that to the user with some extra information. Our Alert Dialog will have title , message and Two button with Yes and No Options. 

if  user select Yes we will recall the requestPermission() method. The Following Code create the AlertDialog.
