How can I validate a URL in android

Question

How can I validate URL in android... I am trying to use regex but it is always returning false even if the url is correct

Code used:

private boolean checkEmail(String email) {
        return URL.matcher(email).matches();
}
    public final Pattern URL = Pattern.compile(
              "/((([A-Za-z]{3,9}:(?:\\/\\/)?)(?:[-;:&=\\+\\$,\\w]+@)?[A-Za-z0-9.-]+(:[0-9]+)?|(?:ww‌w.|[-;:&=\\+\\$,\\w]+@)[A-Za-z0-9.-]+)((?:\\/[\\+~%\\/.\\w-_]*)?\\??(?:[-\\+=&;%@.\\w_]*)#?‌(?:[\\w]*))?)/"
      );

I have got very basic knowledge in regex, so I don't know whether the above used string is correct. Please help...

Thanks for your answers :) One more thing how can I validate without `http://` or `https://` ie the websites starting with `www` should be considered valid — ganapathy, Mar 31 '14 at 19:32

As your question is more specific to android. You can use this

android.util.Patterns.WEB_URL.matcher(url).matches();

In case you want to find a URL inside a text comprised of string other than just the URL, use this

Patterns.WEB_URL.matcher(bodyText).find()

matches() tries to match the string length to exactly that of the URl, while find() will look for the string in the entire text
