How to extract all the URLs from the text in android

I want to get all the URLs from the given text using Patterns.WEB_URL.matcher(qrText);

What I want to do:

I am scanning a QR code,

What I have tried:

private void initialize() {
    if (getIntent().getStringExtra(Constants.KEY_LINK) != null) {
        qrText = getIntent().getStringExtra(Constants.KEY_LINK);
        webMatcher = Patterns.WEB_URL.matcher(qrText);
    }

    if (qrText.contains("veridoc") && webMatcher.matches()) {
            //if qr text is veridoc link
            Log.e("veridoc link", qrText);
            setupWebView(qrText, false);
        } else if (webMatcher.matches()) {
            //if qr text is link other than veridoc
            Log.e("link", qrText);
            openInBrowser(qrText);
            finish();
        } else if  (qrText.contains("veridoc") && webMatcher.find()) {
            //if qrText contains veridoc link + other text.
            String url = webMatcher.group();

            if (url.contains("veridoc")) {
                Log.e("veridoc link found", url);
                setupWebView(url, true);
            } else
                showQRText(qrText);
        } else {
            //the qrText neither is a link nor contains any link that contains word veridoc
            showQRText(qrText);
        }
    } 
}

In the above code,

The Issue

When the text contains some text and more than 1 link, String url = webMatcher.group(); always fetches the first link in the text.

What I want

I want all the links from the text, and find out that which links contain the word "veridoc". After that I would like to call the method setupWebView(url, true); .

I am using following link and text for Example

name: Something Profession: Something link1: https://medium.com/@rkdaftary/understanding-git-for-beginners-20d4b55cc72c link 2: https://my.veridocglobal.com/login Can anyone help me to find all the links present in the text?

You can loop on find to find the different websites and setup arraylists with that

Matcher webMatcher = Patterns.WEB_URL.matcher(input);
ArrayList<String> veridocLinks = new ArrayList<>();
ArrayList<String> otherLinks = new ArrayList<>();

while (webMatcher.find()){
    String res = webMatcher.group();
    if(res!= null) {
        if(res.contains("veridoc")) veridocLinks.add(res);
        else otherLinks.add(res);
    }
}

Given a sample input like :

String input = "http://www.veridoc.com/1 some text http://www.veridoc.com/2 some other text http://www.othersite.com/3";

Your ArrayLists will contains :

veridocLinks : "http://www.veridoc.com/1", "http://www.veridoc.com/2"
otherLinks : "http://www.othersite.com/3"
