What's the best way to check if a String contains a URL in Java/Android?

Question

What\'s the best way to check if a String contains a URL in Java/Android? Would the best way be to check if the string contains |.com | .net | .org | .info | .everythingelse

Answer 1

Best way would be to use regular expression, something like below:

public static final String URL_REGEX = "^((https?|ftp)://|(www|ftp)\\.)?[a-z0-9-]+(\\.[a-z0-9-]+)+([/?].*)?$";

Pattern p = Pattern.compile(URL_REGEX);
Matcher m = p.matcher("example.com");//replace with string to compare
if(m.find()) {
    System.out.println("String contains URL");
}
