I want a chrome browser like behavior where when a user enters a string, the browser decides whether to treat the string as a web address or Google query string.
How can I achieve this ?
I am trying,
boolean modifiedUrlValid = Patterns.WEB_URL.matcher(modifiedUrl).matches();
But this is not working on Android 5.0 and above. Please help.
Regards,
This is a modified version from the original sources for Patterns, does this work? Use it the same way you used the original one.

It was last updated by Google in 2011 meaning that it doesn't match a lot of domains that were recently added. See here for the current list of TLDs. You can keep adding the domains to the source above and it will ultimately have a negative effect on the performance of matching
EDIT: Don't use URLUtils, as it only validates if String starts with http:// or https://
boolean isValid = URLUtils.isValidUrl(urlString);
