Use jNAOqi with Android

Question

I'm currently working with Aldebaran-Robotics' NAO (v3.3) and I was wondering if I can use the jNAOqi-SDK within Android to control the robot from a phone or tablet.

Using the SDK with basic java in Eclipse was pretty simple as described in this tutorial, so I tried to do this in ADT Eclipse. I imported the *.jar-file and placed the precompiled libjnaoqi.so from the package in libs/armeabi and libs/armeabi-v7a, but calling System.loadLibrary("jnaoqi") or System.loadLibrary("<jnaoqi>") resulted in the following error at runtime:

I/dalvikvm(2019): Unable to dlopen(/data/data/com.example.hellonao/lib/libjnaoqi.so): Cannot load library: link_image[1995]: failed to link libjnaoqi.so

I checked the filesystem, but the file was in the lib folder as expected, so I guess it has to be a problem with the library itself.

It's just a shot in the dark but do I have to recompile the library using ndk and naoqi?

Answer 1

I quickly abandoned my project but Aldebaran was busy in the meantime. I recently found a thread about it in the Aldebaran community (login required), where two employees (Nicolas Rigaud and Erwan Pinault) mention upcoming Android support.

nrigaud:

there will be a better Java SDK on our next software version. Meanwhile, it's true that it's not that easy to do Java on the robot

epinault:

In the next SDK you will have library (jar/so) for android
