Kotlin Android Google Map Search Location

In the previous tutorial, we build the application that locate the Map Fixed Location and Map Current Location.

In this tutorial, we will implement search location functionality in Google Map. The searching of Google location is done through Geocoder class. Geocoder class facilitates the geocoding and reverse geocoding.

Geocoding is a process in which street address is converted into a coordinate (latitude, longitude). Reverse geocoding is a process in which a coordinate (latitude, longitude) is converted into the street address.

Methods of Geocoder class

  1. List
    getFromLocation(double latitude, double longitude, int maxResults): This method returns an array of Address which specifies the surrounding latitude and longitude.
  2. List
    getFromLocationName(String location, int results, double leftLatitude, double leftLongitude, double rightLatitude, double rightLongitude): This method returns an array of Address which describes the given location such as place, an address, etc.
  3. List
    getFromLocationName(String location, int results): This method returns an array of Address which describes the given location such as place, an address, etc.
  4. static boolean isPresent(): This method returns true if the methods getFromLocation() and getFromLocationName() are implemented.
