Unexpected e_machine: 3 in KaliumJNI for Android

I am trying to use the crypto libsodium library (NaCl portable version (nacl.cr.yp.to)) on Android, but I cannot figure out how to properly compile / use Kalium-JNI binding .

So far, I have successfully compiled libsodium as described on the libsodium website. In addition, I used a new script compiler added 3 days ago. As a test, I compiled the version of android-x86, and also compared the file sizes of the resulting library files. They are different from each other, so it seems that they work. As a next step, I installed KaliumJNI using the newly created android libsodium files. There are no problems.

In my small android-maven-test application, which is basically the "Hello World" archetype, I'm just trying to create a new key pair:

import org.abstractj.kalium.keys.KeyPair;
KeyPair Alice = new KeyPair();

IntelliJ successfully compiled my small program, but when I try to run it on an emulator (or on my Nexus S), it will work. At first it crashed because it could not find the kaliumjni library, so I added libtestjni.so (which is the .so library created by KaliumJNI) for my project properties that fixed this problem. The following error message I received told me that libtestjni.so is not 32bit (I have 64-bit Ubuntu 12.04LTS). I don’t understand why this should be 32 bits, but in any case I managed to create a 32-bit Ubuntu 12.04LTS VM and a compiled version of libsodium and KaliumJNI to create a 32-bit libtestjni.so file. But when I use this 32-bit file in my original application (on my 64-bit computer), I get the following error:
