• A Google developer has hinted that early Android Q builds may reach more users next year thanks to prospective Generic System Image (GSI) developments.
  • The moves could allow any Project Treble-supported device, not just select handsets, to run previews ahead of the software’s full launch.
  • The developer said there may be a way to test Android Q without physically flashing the GSI in future, too.


A Google engineer has hinted that Android Q previews may be available on more devices than ever before ahead of its full-scale release in 2019. The engineer, Hung-ying Tyan of Google’s Project Treble team, made the comments during Android developer summit last week (via XDA Developers).

Hung-ying was holding a talk on Generic System Images (GSIs). A GSI is a pure version of Android based on the Android Open Source Project (AOSP) code used to test compatibility on Android smartphones. In order to benefit from quick updates via Project Treble, for example, a hardware manufacturer must be able to boot a GSI and ensure it works correctly on their device.

This is a key part of Project Treble, but it seems Google wants to diversify GSI use cases. Hung-ying said the team is “exploring ways to make future GSI available earlier than the release of next Android version. So you will be able to try out next Android version earlier over GSI.” This, according to Hung-ying, would be mutually beneficial, seeing as more users would get access to the software the team could receive earlier feedback.

What’s more, Hung-ying said that there might be a way to test out GSI, without flashing it, in the future — something which can be a tricky process.

What this would mean for Android fans is that more people could gain access to the early version of Android Q (the upcoming version of Android), sooner. With the Android P Developer Preview, Google allowed Pixel users (and later some other Android device owners) to test the software from March last year ahead of its full release in August. The implication of GSI becoming available earlier is that any Project Treble-equipped phone would be able to install the next Developer Previews — opening them up to many more users.

This is just a possibility for now, but Hung-ying said we should stay tuned for more information in the future. It seems like it could happen.
