Failed Dynamic Loading of Unity Asset Libraries in Android

Unity Asset Library contains 3 libs (libMain.so,libIl2cpp.so,libUnity.so) out of which i'm able to load libUnity at runtime in my android app.if i try to load both libil2cpp and libUnity libs at runtime i'm getting a message saying "Failed to Load il2cpp" while creating apk i'm removing libIl2cpp.so and libUnity.so from the apk so that i can reduce the size of apk and when app launches for first time.For loading the library i'm using Facebook's soLoader Library.

![alt text][1] did anyone else tried doing it.any success?
