Fridgimon

Fridgimon started as a joke. Playing with a Zebra MC18 barcode scanner, I said I should write an app that keeps track of the contents of my fridge, reminding me when stuff goes out of date. So I wrote an app that keeps track of the contents of my fridge, reminding me when stuff goes out of date.

Fridgimon is a webapp in React, with a PHP backend that talks to the database. It also contains the configuration to load this webapp in Zebra's Enterprise Browser, a customised browser environment with full access to the device functionality including the barcode scanner.

Installation

Web application

1. Create the database schema from src/fridgimon.sql.
2. Copy src/webapp/db.sample.inc.php to src/webapp/db.inc.php and populate with your MySQL connection details.
3. Setup an Apache vhost with the document root of src/webapp.
4. Allow the PUT and DELETE methods for the src/webapp/api directory, either in the global apache config, or the vhost entry, e.g.

   <Location /api>
       AllowMethods GET POST PUT DELETE
       Require all granted
   </Location>
   

   (Note, you cannot add this to .htaccess)
5. Open the browser and navigate to http://yourhost/eb/, and you should have a page with the Fridgimon title.

Enterprise Browser

(The instructions below assume a device running Android Lollipop that has been reset back to default, but can apply to WinCE with adjustments)

This will require copying files to your MC18 scanner, which can be done via a file manager app on the device itself, or by acquiring or fabricating a USB cable and using ADB and file MTP transfer.

1. Update the StartPage entry in src/EnterpriseBrowser/Config.xml to point to your configured website address.
2. Backup the contents of SD card\Android\data\com.symbol.enterprisebrowser on the device.
3. Copy the contents of src/EnterpriseBrowser to SD card\Android\data\com.symbol.enterprisebrowser on the device.
4. Restart EnterpriseBrowser from the launcher, and it should load up to the Fridgimon app.
