Design, Develop and Distribute: Player FM at Google IO Developer Sandbox

It’s official: Player FM will be participating in the Developer Sandbox at Google IO 2014.

The IO Developer Sandbox showcases demos from a wide range of developers who have built applications based on technologies and products that are featured at I/O. We have been invited to demo our application and connect with I/O attendees developer-to-developer to answer questions and exchange ideas.

The conference theme is Design, Develop and Distribute, and we’re looking forward to sharing lessons and swapping war stories with developers about all of these activities. Here’s a quick overview on how we approach each of them — find us at IO or drop me a line to dive deeper on these.


The most enlightening thing about IT in the past 10 years has been design getting the recognition it deserves. Certainly, it’s about visual design that delights users, but much more than that, it’s about interactions, features, and concepts that make apps “just work”.

Player FM plays podcasts. That’s hardly a new concept, so why make a YAAP (yet another podcast player). Yes, design! The fundamental problem a podcast app must solve is “How do I listen to topics I care about?”. New Player FM users immediately choose favourite topics, even if they don’t know any individual shows, and they’re immediately listening to them. Meanwhile, the app syncs recent episodes for offline use, saving them the hassle of download management.

Notice I didn’t mention anything about colors, gradients, or round corners above. Visual design matters more than ever, but it’s the price of entry for a consumer-facing app. On Player FM’s Android app, we do spend a lot of time iterating on visual designs and sweating each pixel, but ultimately the big challenge is moving forward while balancing simplicity and control.


As a small operation, developer productivity and server efficiency matter a lot. Not only does it keep costs low, but it lets us learn from feedback and iterate quickly.

Continuous integration is one of the ways we achieve this on the server. Automated testing gives enough confidence to release several times a day. Server configuration management via Ansible (similar to Chef and Puppet) lets us scale and load-balance for better uptime. Leveraging open source and contributing back helps us add new features quickly. As for the API consumed by the mobile app, we take advantage of REST and HTTP to keep bandwidth and battery usage as low as possible.

Developing’s all about the detail, so there’s not much more to say in this short summary, but I’ll be happy to talk code at IO and might even open up a Vim session or two :).


Users experience Player FM on both Android and the web, and each has their own distribution strategy.

On Android, we make use of Play, receive valuable feedback, and are pleased to be able to comment and follow up on reviews. We also benefit from the private and staged rollouts which were announced at none other than Google IO last year. Oh and you should totally join our pioneers community for early access to features! Including the speed control that will be part of the imminent Player FM 2.0 release.

As for the web, that’s where Player FM initially launched. One of the goals was to make podcasting more accessible to a broader audience, people who have never considered installing a podcast app. Maybe people who’ve never installed any app at all. HTML5 provides a powerful platform for delivering an app-like experience without any installation process. And Chrome’s developer tools help to debug and improve the website. I’m currently working to improve the mobile web experience, and it’s amazing how much easier it is to do this now, compared to just a couple of years ago.

See you at IO

Google IO attendees work on many and varied applications, yet many face similar challenges and stand to benefit from similar solutions. Hopefully the above points give you a sense of how Player FM approaches design, development, and distribution, and we’re looking forward to sharing more about them at next month at IO.
