In a very surprising move, Google has started pushing the source code of the recently released Developer Preview build of Android L to AOSP. This is the first time that the company has pushed the sources of a yet to be released Android version to AOSP.

The source code is mainly meant for developers who can now tinker around with the OS to their liking and create ROMs and rich apps that might require root access to work properly.

The source code also confirms one major mystery revolving around Android L and its compatibility with existing Nexus devices. Since Google only released the Android L Developer Preview builds for the Nexus 5 and Nexus 7 (2013), many people assumed that the Nexus 4, 7 (2012) and Nexus 10 will not be getting the update since it falls outside of the 18 months update cycle for Nexus devices.

However, with Google pushing L’s platform dependent source code to AOSP for these devices, it is all but confirmed that they will be getting the final update to Android L as well later this year.

At the moment, Google has not yet released the binaries for these devices yet, so users will have to wait a bit longer for AOSP compiled ROMs for these devices to show up. But once they are released, expect plethora of Android L based custom ROMs to show up for the Nexus 4, 7 and 10.
