you cannot fetch phone number of user.

to fetch location, need the:

  • api call: /me?fields=location - demo

  • permission: user_location check here how ask additional permissions using android sdk.

code location:

new request(    session,    "/me?fields=location",    null,    httpmethod.get,    new request.callback() {      public void oncompleted(response response) {          /* handle result */      }    } ).executeasync();

see fields available user: /{user-id}
