How to check if URL is valid in Android

Question

Is there a good way to avoid the \"host is not resolved\" error that crashes an app? Some sort of a way to try connecting to a host ( like a URL ) and see if it\'s even vali

Answer 1

I would use a combination of methods mentioned here and in other Stackoverflow threads:

public static boolean IsValidUrl(String urlString) {
    try {
        URL url = new URL(urlString);
        return URLUtil.isValidUrl(urlString) && Patterns.WEB_URL.matcher(urlString).matches();
    } catch (MalformedURLException ignored) {
    }
    return false;
}
