UnsatisfiedLinkError for android library

Hello everyone,

In my project, I would like to use the ZBar library in order to be able to read QR code.

For test purpose, I've created a simple Android Library with a simple function which do nothing but displaying a log. When importing this library to my unity project, everything works fine.

from this point, I've added in my java class the following code in order to be able to start a QRCode reader: static{ System.loadLibrary("iconv"); }

After Adding the above code, when trying to create my AndroidJavaObject in a C# script, I have the following error:

Exception Ljava/lang/UnsatisfiedLinkError; Thrown while initializing Ljp/XXX/XXX; AndroidJavaException: java.lang.ClassNotFoundException: jp.XXX.XXX

...

caused by: java.lang.UnsatisfiedLinkError: Couldn't load iconv from loader dalvik.system.PathClassLoader[...]: findLibrary returned null

In the Assets folder, I have the following setting :

-Plugins

      -QRCodeManagerScript.cs <- this script will call my library using AndroidJavaObject
      -Android
             -zbar.jar
              -mylib.jar
              -armeabi
                      -libiconv.so
                      -libzbarjni.so
              -armeabi-7a
                      -libiconv.so
                      -libzbarjni.so
              -x86
                      -libiconv.so
                       -libzbarjni.so

Could you please tell me if a static library can be use/loaded inside my own library?

I really thank you in advance for your help.
