Ask HN: Significant commit rate decline of Android's base repository?

Most of the development happens behind closed doors. The AOSP repositories/public branches are updated after the release comes out.

Not sure. Several of high change frequency components from telephony were moved to platform/packages. Also Google has probably not dumped the latest changes yet.

What does this mean? The phone manufacturers handle it now? Is platform/packages not open source?

platform/packages is open source, but I guess the split is done so that the manufacturers can ship their own versions of these components. Also I guess manufacturers are more responsible for these components now.

Google Play Services (a closed source, Google-copyrighted component) has been slowly eating more and more of the stuff that was previously handled by AOSP.
