We all know that getting OS updates on Android devices is a bit of a pain. With Project Treble, unveiled today on the Google Developer Blog, Google’s finally looking to change that with a rework of some of the underlying architecture to make updates easier.
It’s not the first time Google’s tried to address complaints about Android’s fragmented nature. We’ve seen a few efforts the Update Alliance, we’ve seen vendors pledge to keep up with updates (and fail), and most recently we’ve seen Google start to enforce adherence to Android’s regular security patches. The result is still the same – unless you’re on Google’s own Nexus or Pixel devices, getting an OS update is a case of playing the waiting game.
There’s a number of reasons for the delays, and they’re surprisingly not just vendors being lazy. Android’s underlying architecture requires updated drivers for device components as new versions of the operating system are released, and some vendors don’t like to update drivers for old components, and not necessarily in a timely fashion.
It’s a dirty little secret of Android updates, and it’s a finger we’ve seen pointed in recent years — as old devices fall out of favour, the drivers for their components fall behind and don’t get updated. If device manufacturers can’t get new drivers for all their components, their phone or tablet is essentially dead in the water when it comes to updates.
Google’s seeking to change this by taking the a similar approach to drivers and vendor customisations that they’ve taken to Android apps – building a stable and reliable compatibility layer.
Project Treble brings this in the form of a software Vendor Interface that’s designed to be forwards-compatible.
With a stable vendor interface providing access to the hardware-specific parts of Android, device makers can choose to deliver a new Android release to consumers by just updating the Android OS framework without any additional work required from the silicon manufacturers
Trebles are threes, and the project’s name brings about a three-tier architecture for Android that’s all about ensuring compatibility between versions now and into the future.
The best news is that this isn’t a theoretical change or a proposal – it’s up and running already in the bleeding-edge Android O preview that’s running on a number of Pixel phones, and it’ll be there in all O-powered devices. You just need to get your device onto Android O, first…
All of this is geared towards making it faster and easier for device manufacturers to update the Android OS to get the latest and greatest software, faster. While Google’s also talking about device manufacturers using the Vendor Interface to handle their customisations, they haven’t gone into much detail in today’s post about it. We’ll have to wait and see what our OEMs have to say about it.
