Google launched the new Project Treble along with Android Oreo last year which was made available for OEM to push Android updates faster. Last week Google demonstrated the new GSI engine running on various devices from different brands.
Now Google has made a blog post where it confirms the devices launched with Android 9 Pie will come with Project Treble support. Further Google expects the number of devices to run the new Android 9 Pie update by the end of 2018. With the new GSI which is built on the latest AOSP source code brings lots of bug fixes.
With the latest, GSI Android Developers will have full freedom to test the apps on pure AOSP ROM. GSI could enable early access to future Android platform builds that you can run on a Treble-compliant Android 9 device, so you could start app development and validation before the AOSP release.
