Hello Folks in this post I’m going to provide you the code of the Covid 19 Tracker which I created Last year and demonstrated over my youtube channel.
The problem is on that tutorial I forgot to add one important point which is Remote site Settings. So before you start writing Code make sure you create a remote site setting for the API.
To add a remote site setting:
- From Setup, enter Remote Site Settings in the Quick Find box, then select Remote Site Settings.
- Click New Remote Site.
- Enter a descriptive term for the Remote Site Name.
- Enter the URL (https://api.covid19api.com)for the remote site.
- Optionally, enter a description of the site.
- Click Save.
