How to maintain android binaries checksum intact. after rebuild of AOSP.

[prasannakulkarni]

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.

Hello Prasanna Kulkarni,

I would recommend looking on Google Developers forums for information on whether it is possible to edit the checksum settings on the AOSP not to take the time-stamp into account.

My apologies for the inconvenience.
