According to your call stacks it crashed inside MMKV::filterExpiredKeys() which is weird. Can you provide a reproducible demo project or the relative MMKV files (including the *.crc file)?

#00 pc 000000000004d390 /data/app/~~T-JKFhIKj06ljqCd-jqv2Q==/com.xxxxxx.xxxxx-_eQ5My7wQ0SIDcPukAnTOw==/lib/arm64/libmmkv.so
    MMKV::filterExpiredKeys() at MMKV_IO.cpp:1822

[wuangruaingzua]

MMKV files

mmkv.zip

[lingol]

According to the logs, I guess it crashed on loading the default MMKV instance, right?
What exactly is your code to load the default MMKV instance?

[wuangruaingzua]

private val defaultMMKV: MMKV by lazy { MMKV.defaultMMKV().apply { enableAutoKeyExpire(MMKV.ExpireNever) } }

[lingol]

MMKV.cpp:423::checkFileCRCValid check crc [mmkv.default] fail, crc32:286753061, m_crcDigest:2247816363

The file is corrupted. It is not the original make.default & make.default.crc file when your crash happens.
Please provide exactly the same file when it happens.

[lingol]

The root cause is that your metafile (mmkv.default.crc) has the flag that AutoKeyExpire is enabled, but the data file (mmkv.default) is not actually in the format. Enabling auto-key-expiration is a breaking change API, once you enable it, the data file's format will change completely.

• Is it possible that there's an interruption when you enable it?
• Is it possible that the metafile and the data file are not from the same place, for example from another device by some backup & restore tools, or by cloud sync?

Can you provide a demo project that reproduces this problem, starting from the very beginning when mmkv.default is not auto-key-expire, and then auto-key-expire is turned on, and then it's corrupted?

[wuangruaingzua]

Thank you for your detailed explanation regarding the issue with the metafile and data file in MMKV.
It is indeed clear that the problem arises from enabling AutoKeyExpire, which leads to a breaking change in the data file format. Your suggestions regarding potential interruptions during this process and the possibility of mismatched files from different sources have been invaluable in our troubleshooting efforts.
At this time, we have not been able to reproduce the problem consistently. It appears that only a subset of our users is encountering this issue, which makes it a bit more challenging to diagnose.
