permission to know phone number : i am an indie app developer,i have an android game in play store and have around 150 active users.
i am adding leadersboard in the upcoming update
so that people can compete with each other.
my app does not require access to any specific permission.
however i want to know if there we can know the contact number of a user who downloads our app so that we can
send a congratulation message when someone reach at the
top of the leadersboard.
Can anyone please tell me how it can be done in android studio and if yes,where can we view the number.
