A4.1 - UnsatisfiedLinkError: Couldn't load X: findLibrary returned null

[Menion]

Good day to all,

  I have for a few months quite well working application on Google Play. Since today update, I already received into Developer console this error

java.lang.ExceptionInInitializerError

From few emails and reports I discovered that this happen only on Android 4.1 or 4.1.1. All other users have no problems. MaCore library is quite a small library (one *.h and one *.c) with four functions. I discovered an incorrect values in header file, but even after recreating, problem remain. Also on my 4.1.1 device I don't have this problem. And finally, some users (two to be exact), wrote me that after re-install of application, all works fine! Have anyone any suggestion, what should I do and where to search for some solution? Thanks!

I just wanted to write that as a reaction to today update I already received around 70! Stack traces, so it's not a one-man issue. That's why I need to fix this in some way

Hey I had the same error. This means the library is not linking correctly . just try changing the Android.mk file to make this lib load statictically . the BUILD_SHARED-> BUILD_STATIC . I hope you got that .

Cheers , Let me know.

isn't weird that this affect only A4.1 devices (I have really minor knowledge about C dev, so sorry for these questions) and also that re-install helps?

I'll check it tomorrow on some users that wasn't fast enough to re-install

This appears to be the same issue as:

Excellent Dan, it's absolutely identical problem, I'll continue in discussion there. That's what I was looking for, thanks you very much!
