BUILDING external libs: Crash in cn_slow_hash()

[Pei116]

I followed your instructions to build the monero wallet lib for Android according to BUILDING external libs. But it's always crashed in Android. ` 08-18 03:46:14.587 26496-26496/? A/DEBUG:

` I tried several suggestions but no luck yet. Any advice will be appreciated.

what are you trying to do?

run addr2line (https://stackoverflow.com/questions/5314036/how-to-use-addr2line-in-android) to find out which memcpy in cn_slow_hash() is crashing (you will need to build debug libraries - build_type=debug) or output lots of debug logs. and then you can look into why.

@Pei116 what's the news on this?
