Sony Xperia S has been removed from the Android Open Source Project (AOSP) and is now available from the company’s own GitHub. At its developer blog, Sony said that Google’s can’t maintain non-Nexus devices on the AOSP main branch in the long run, hence the project is now residing on other (Sony) servers.
Google’s “Android Open Source Tech Dude” Jean-Baptiste Quéru on its end said that Sony is now the company with the expertise needed to carry on the project. In addition, Sony never released all the binary files needed to boot the Xperia S into a usable state.
As for the current status and progress of the AOSP on Xperia S project, the software now boots up, and the SD-card, Wi-Fi and sensors are working properly, with audio and modem capabilities being tested internally (though they require some proprietary binaries which are still not available). Going forward, the next steps are to replace some of the previously published binaries with source code, and to get Android 4.2 working on Xperia S.
