How to get Latitude and longitude coordinates from the text address in your Android App without maps layout using Geocoder API?

This video shows the steps to get latitude and longitude coordinates from the text address. It uses Geocoder APIs to get the address list. In this video it just fetches the 1st most probable address matching the text string. However, for more advanced location search one can filter the addresses from the list based on various parameters.

I hope you like this video. For any questions, suggestions or appreciation please contact us at: https://programmerworld.co/contact/ or email at: programmerworld1990@gmail.com
