What version/fork of Android are you building? `dhcpd-hooks` doesn't appear to exist in master, or any previous versions of AOSP that I can easily search.
Looking back, it looks like I didn't expect odex files to be stable until Android O, though even then they tend to be rather fragile, since it's easy to make dex2oat non-deterministic. We don't have any automated testing around reproducibility yet, though I'm hopeful we can get some set up soon. - Dan On Thu, Dec 27, 2018 at 12:02 PM <[email protected]> wrote: > > > Hi All, > > As per the Group suggestions I have fixed the BUILD_NUMBER, > DATE, TIME etc. Despite doing all those things it is differing. my Expt is > like this > > 1. make clean and build get system.img -> rename to system-1.img > 2. make clean and build get system.img -> rename to system-2.img > > What I was assuming that until and unless I actually modify > source code and build, checksum of system-1.img and system-2.img would > remain same.
