He followed this up this morning by saying that the reason it was removed was that it was not being used. So keeping the code in there increased the overall package size.
Spread out over billions of devices and small changes make a huge difference. He also stated metered data plans as a primary motivation.
You're referencing a different thing. This is the open source version bundled into AOSP, not the Google Play Services version.
Directly from the source:
So, as I suspected, Fast Pair code was deleted from AOSP because it wasn't being used by anyone.
And because it wasn't being used, it was just taking up space unnecessarily. Although HalfSheetUX was only a few megabytes in size, Mainline modules are served to many millions of people, a decent portion of whom are on metered connections.
Note: This has no implications for the Fast Pair feature you're already familiar with. Fast Pair started out as a feature bundled in Play Services and will remain that way for the foreseeable future. This news just means there's no longer an open source version of Fast Pair.
Yes and it is worrying. Google ought to make everything AOSP and but keep anything proprietary. They have nothing to lose so I don't understand why they are stripping stuff from AOSP.
They removed a rarely used function from the free android open source project to a paid, closed source program that Samsung/Xiaomi/OnePlus/Sony/etc are already paying.
This affects only who uses Amazon or Huawei devices (or a Google-less custom ROM)
But while nobody cares about this specific function, Google is slowly removing features from the open source project year by year. The calculator, the calendar, the email client, and so on
Also both Amazon and Huawei never used the AOSP Fast Pair. Huawei has their own proprietary implementation which was there before even Google came up with Fast Pair and FireOS is still on Android 11.
I'm convienced in next 5-10 years I won't be using Android anymore.
This is sinking boat, the only thing keeping me on it is that other boats are just being build.
