In particular, bsdiff has been around for a very long time and is an industry standard binary diffing tool.
- samhw 5y agoYeah, I mentioned bsdiff in my original comment. I don't think Android uses it for operating system updates, though, as far as I can tell. I believe that page is describing APK updates (i.e. app updates).
- howinteresting 5y agoWell, monthly OS updates for Android tend to be just a few megabytes, so I'm presuming they use some sort of binary diffing algorithm.
