Just to answer my own question.

I was linking to the wrong libQCAR.so when building native code.
For anyone else with this problem take a look at your Android.mk file and make sure all your paths are correct.

I have changed the classpath variable but for some reason I'm still getting 1.5.4 instead of 1.5.9.
I've even renamed the 1.5.4 directory so nothing should be pointing to it.

The steps I have done:
Downloaded and installed the SDK directory (Linux)
Changed the classpath variable to pint to 1.5.9
Checked project build path: "QCAR_SDK_ROOT/build/java/QCAR/QCAR.jar"
ndk-build -B to rebuild libraries
Cleaned project
Run

Still showing 1.5.4

Any thoughts?
Or any hidden connections to 1.5.4 you know about that I can change?

It doesn't look like you've successfully upgraded:

I/AR ( 4973): QCAR SDK version 1.5.4

That's still the beta version. Have you pointed the Eclipse QCAR_SDK_ROOT variable to the new SDK? Rebuild the .so libraries using "ndk-build -B" to force a rebuild. Then clean and rebuild the Eclipse project.

I'm actually getting a crash in ICS.
The same code works on Android 3.2 but not on Android 4.0.3.
Any suggestions?

ICS crash dump can be found here: http://pastebin.com/BjjXSnqA

This is just from updating to 1.5 from 1.5 beta without any code changes.

Support for ICS is here as of today :) Check out the new 1.5 release!

Hi, I have the same problem. I'm using a Samsung Galaxy Nexus and bought it just for developing AR-applications with QCAR. Is support for Android 4.0 far away?

Hello,

Can you let us know what device you have? You should be able to download an official gingerbread ROM, copy it to your SD card, and restore your phone using the restore menu at startup. You can do this without rooting your phone. I'm sorry for the inconvenience.

Thank you,

-Peter

Unfortunately, no.
I would have to root my device and void my warranty for that.
