# WebURLFinder

`class WebURLFinder` [(source)](https://github.com/mozilla-mobile/android-components/blob/master/components/support/utils/src/main/java/mozilla/components/support/utils/WebURLFinder.kt#L22)

Regular expressions used in this class are taken from Android's Patterns.java.
We brought them in to standardize URL matching across Android versions, instead of relying
on Android version-dependent built-ins that can vary across Android versions.
