Making Links Clickable in a TextView: A Comprehensive Guide

This tutorial will delve into how to make links in a `TextView` clickable in Android, covering various approaches, best practices, and considerations for creating a user-friendly and accessible experience.

*Why Make Links Clickable?*

Displaying URLs or other text-based links within a `TextView` is a common requirement in many Android apps. However, simply displaying the text isn't enough; users need to be able to interact with these links, such as:
