Re: [android-building] How to maintain android binaries checksum intact. after rebuild of AOSP.
We work pretty hard to make sure that the contents of the system image don't change unless the source tree is changed, and AOSP master should be in pretty good shape, although bugs do creep in sometimes. The build time and build number are stored in system/build.prop and change on every build though. The build number can be fixed on the command line with m BUILD_NUMBER=12345, but there is currently no way to fix the build date. You would need to edit build/make/tools/buildinfo_common.sh to not use $DATE to get the current timestamp. We would accept patches that made the build date settable from the command line.

[android-building] AOSP flashing Pixel 3 XL with fastboot
I am trying to flash my Google Pixel 3 XL with my locally built AOSP. The build and flash seem to go smoothly, but the phone does not start up. At startup, the Google logo is seen shortly and then the phone boots again. I do not think there is anything wrong with the phone. When the phone is flashed with a factory image (crosshatch-pq1a.181205.006-factory-96b23504), everything works fine The AOSP repository has been retrieved with repo init -u https://android.googlesource.com/platform/manifest -b android-9.0.0_r21 --depth=1 compilation seems to work fine, flashing with fastboot -w flashall also completes without problems, but the phone doesn't start up. The interesting thing is that I have previously built an AOSP for a Pixel XL and that went fine, so it looks like some strange difference between Pixel and Pixel 3. I realize that there is a previous thread on something similar https://groups.google.com/forum/#!topic/android-building/lmCUWEgoaKQ but it was not clear what could be done to solve the problem. Any feedback would be highly appreciated. -- -- You received this message because you are subscribed to the "Android Building" mailing list.

[android-building] How to maintain android binaries checksum intact. after rebuild of AOSP.
Hi Android Experts, We need some help / information that, Is there any way to keep android images (system.img, boot.img etc ) checksum [md5sum/crc32] same even after fresh build or recompilation??. Even though without changing a single bit in the AOSP Source code if we rebuild it, Android binaries checksum keeps changing. As I can understand that the compilers/linkers adds the date and time-stamp to the images/binaries after each build which causes the change in the checksum. So my question, Is there any way to avoid this change in image checksum after every rebuild. it should change only when we change any source code. kindly update. -- -- You received this message because you are subscribed to the "Android Building" mailing list.
