Why shouldn't exceptions be ignored in Java development?

Don't ignore exceptions

public static Bundle decodeUrl(String s) {
    Bundle params = new Bundle();
    if (s != null) {
        String array[] = s.split("&");
        for (String parameter : array) {
            String v[] = parameter.split("=");
            try {
                params.putString(URLDecoder.decode(v[0], "UTF-8"), URLDecoder.decode(v[1], "UTF-8"));
            } catch (UnsupportedEncodingException e) {
                e.printStackTrace();
            }
        }
    }
    return params;
}
