If you have a certificate that is not
trusted by Android, when you add it, it goes in the personal cert store.
When you add a cert in this personal cert store, the system requires a
higher security level to unlock the device. But if you manage to add your
cert to the system store then you don't have this requirement. Obviously,
root is required to add a certificate to the system store, but it is quiet
easy.

SheetAsJSON + Filtering

This is an extension of DJ Adams' excellent SheetAsJSON Google Apps Script, which provides a way to GET a published Google Spreadsheet as a JSON feed. This version allows generic filtering for terms, more specific control over which rows to parse, and correct MIME type for JSONP output.

Minimal Usage

The following parameters are required for the script to work.

https://script.google.com/macros/s/AKfycbzGvKKUIaqsMuCj7-A2YRhR-f7GZjl4kSxSN1YyLkS01_CfiyE/exec?
+ id=<spreadsheet key>
+ sheet=<sheet name on spreadsheet>

<script type="text/javascript">
    (function () {
      "use strict";
      // once cached, the css file is stored on the client forever unless
      // the URL below is changed. Any change will invalidate the cache
      var css_href = './index_files/web-fonts.css';
      // a simple event handler wrapper
      function on(el, ev, callback) {
        if (el.addEventListener) {
          el.addEventListener(ev, callback, false);
