Posted November 27, 2019 in Mobile DevelopmentI was watching the evening news one day and started thinking about how much of the show was allocated to different topic categories (local news, national news, sports, etc.); I was especially curious about what the ratio was of news vs. commercials (there seemed to be a lot of car commercials). I decided to build an app that enabled me to capture (measure) the amount of time allocated across multiple categories. I thought perhaps that others would like a similar app, so I decided to publish it as my first app store app.

Posted July 27, 2016 in Mobile DevelopmentI posted a little while ago about how marketing organizations were ignoring mobile clients when crafting email blasts and provided some examples (which I continue to update as I find more). My analysis of these emails focused mainly on how the email messages are not formatted correctly for smaller devices, but as I looked into this more, I realized that many of these email messages, not marketing blasts, but specific notification emails sent directly to me, weren't structured in a way that made them immediately useful to me as the consumer. Take the following email notification from American Airlines for example:
Android HTTP POST Request Using OKHTTP
Posted April 17, 2016 in Mobile DevelopmentI'm not much of a Java developer. I've poked and prodded at it when I worked for BlackBerry and wrote my BlackBerry development book, but I've not done much serious Java development in my career. I've been working on a Particle Photon-based garage door controller and I built a web app and an Apache Cordova version of the app to interact with the controller. I also wanted a native Android app for this, so I got to work learning Android development. I picked up a copy of the Big Nerd Ranch guide to Android Development (https://amzn.to/22D68vF) and got to work.
