[FREE] AddressInfo - Some calculations about address

Description Hello every one..Today I introduce my first extension..It’s an extension that makes some calculation about addresses.. Currently it only supports getting distance between two coordinates..And also indicates if a coordinate is in a radius around a location.. Note: This extension doesn’t use any formula in calculation..It uses a class for calculation provided by android..So calculating is more accurate.. release time : 2020-08-06T23:00:00Z (UTC) current version: 1.2 last update:…
