Amazon Kindle Fire cheat sheet for Android developers

My company recently published our Android app on the Amazon app store for Kindle Fire tablets. While getting ready to publish the app on the store, I realized that the list of Kindle Fire specifications that Amazon has here is neither developer nor customer support friendly.

Kindle Fire devices show system version in this format: 7.5.1_user_5170020. 




This does not convey the Android OS version at first glance. So, if a user or a customer support representative says that your app is not working on a Kindle and they only give you the system version, you as a developer are not sure which version of Kindle it's failing on.

If you are also debugging via USB on a Kindle device, Android Studio only shows you the Build Model and not the OS version.

To solve these issues, I made the cheat sheet below to help Android developers quickly determine which Android OS version a Kindle is on. Hope this helps!

Note: This table is as of March 28 2015.

Running our first GDG Philly Android Study Jam

Recently I joined the fantastic team of developers who run Google Developers Group Philly (GDG Philly), an umbrella organization that includes Android Alliance Philly and GoLang Philly meetup groups. Google Developer Groups or GDGs are community-run groups that are for developers who are interested in learning Google technologies.   The first thing we organized in 2016 was  Google Developers Groups Study Jams , a free series of global, community-run, in-person study groups. We ran an Android Study Jam for 5 weeks which used Udacity's  Android Beginners curriculum  for newbies as well as experienced developers. Image Credit: http://developerstudyjams.com/ Since GDG Philly focuses mostly on Android & GoLang topics, we didn't have to go too far to find facilitators. Three of us organizers - Arpit, Corey & I are Android developers so we split the teaching part into 3 sessions that each of us would lead. The Study Jam ran for

Recap of Android Summit 2017

I recently attended and spoke at Android Summit , an Android conference organized by the folks at Capital One. Special shoutout to Jared A Sheehan, Michael Jones and the entire organizing committee for running a fabulous event which raised $6000 for Women who Code. All speakers received a Phillips Hue Starter Kit as a speaker gift which I've used to toggle and dim my living room lights via Amazon Echo. So much fun! I had a prior commitment and could only attend Day 1 but here are my highlights. Process & Workflow A common theme on Day 1 was process and workflow talks which tied in beautifully with Kelly Shuster 's keynote. Kelly is an excellent story teller. In her keynote, she connected a story of communication from her theatre background to how developers, designers and testers need to work together to reduce boiler plate conversations when designing and developing apps. I gave a similar talk earlier this year at  Chicago Roboto  with my co-worker and designer  J
