     * String.split() returns [''] when the string to be split is empty. This returns []. This does

     * not remove any empty strings from the result. For example split("a,", ","  ) returns {"a", ""}.

     * This method yields the same result as {@code text.split(expression, -1)} except that if

     * {@code text.isEmpty()} then this method returns an empty array whereas

     * {@code "".split(expression, -1)} would have returned an array with a single {@code ""}.

     * The {@code -1} means that trailing empty Strings are not removed from the result; for

     * example split("a,", ","  ) returns {"a", ""}. Note that whether a leading zero-width match

     * can result in a leading {@code ""} depends on whether your app

     * {@link android.content.pm.ApplicationInfo#targetSdkVersion targets an SDK version}
