Google has announced a new security initiative called Project Zero, with the broad mandate of making the internet a more secure space. Full-time researchers will identify threats through the most widely-used applications, submit bug reports directly to the developers, and announce the changes publicly once the vulnerability has been patched.
It's worth noting that Project Zero isn't being limited to Google products; they'll be looking everywhere for breaches in security and privacy, either from criminals, "state-sponsored actors," or anything in between.
Good on Google for supporting a more secure internet, especially considering how big of a role they play in the whole scheme. No doubt many of the gaps they plug will affect Android, although most of these changes are likely to be behind the scenes with little noticeable difference to the end-user.
