how to validate a URL / website name in EditText in Android?

Question

I want to take input, a URL or just a website name like, www.google.com from EditText in Android and on user click on the Button to submit

In case, in your UnitTest, you got NullPointerException then use PatternsCompat instead of Patterns.

fun isFullPath(potentialUrl: String): Boolean {
    return PatternsCompat.WEB_URL.matcher(potentialUrl.toLowerCase(Locale.CANADA)).matches()
}

Also, I realized that this method returns true when I pass it Photo.jpg. My expectation is false. Therefore, I propose following method instead of the above.

fun isFullPath(potentialUrl: String): Boolean {
    try {
        URL(potentialUrl).toURI()
        return true
    } catch (e: Exception) {
        e.printStackTrace()
    }
    return false
}
