As an Android developer, I love that Google is doing this!

Android has come a very long way in the last few years in terms of usability and design. A large part of this has been due to an increasingly uniform design language and feel. That, and the new distribution model for what are basically Android updates (Google Play Services) has made Android feel more polished and actually allowed it to stand on its own against iOS. It also means that developers like me don't have to spend nearly as much time worrying about fragmentation in the traditional sense. Each day the percentage of people using sub-ICS phones falls, and we all get one step closer to the day we can support ICS+ only.

However, companies like Amazon would force me to rewrite the maps integration, the sign-in portion, the wallet, etc... Amazon did a great job of replicating Google Maps API V1 but they have yet to mirror V2 and don't mirror the other components I mentioned.

Aside from fragmentation and developer sanity, the article mentions another key point here:

"[M]any of Google's solutions offer best-in-class usability, functionality, and ease-of-implementation."

Exactly! Google APIs are not perfect, and there's bugs (like when Google Maps broke map markers on high resolution phones like the HTC One). But generally speaking, I'm really happy with the quality of the APIs and services. In an ideal world, Amazon and Google would work together to provide great and uniform single-sign-in APIs, great maps, etc... As it currently stands though, I don't believe either party is interested in doing so. Prisoner's dilemma?
