Simple links in android
There are few things that give a developer more pleasure than finding those small functions and helpful methods that can save huge amounts of work in development. When developing Android apps, one of my very favourite is the Linkify, a small, powerful and configurable utility that automatically adds links to any block of text that you're displaying in your Activity's views.
