Extended Tracking single-core devices support

January 17, 2014 - 3:10am #1

The know issues of SDK version 2.8.7 says "Extended Tracking is only supported on multi-core devices.".

Is Extended Tracking planned to be supported on single-core devices in future releases?

Yes, that could be the reason. I can confirm Vuforia 2.8 supports Arm v7.

Right now I can only provide log from release version. Later I should have also something from debug.

I think I  know the reason - http://en.wikipedia.org/wiki/Samsung_Galaxy_Gio - seems this is ARMv6 and since 2.8 you support only ARMv7. Can you confirm that?

Extended Tracking should simply not work on a single-core, but this should not make your App fail or crash. So, probably your issue is caused by something different. What is the exact error message you get ?

I've failng app on Samsung GT-S5660 (2.3.4) and I'm not sure if this is "single-core" related problem as in case of ex. 4.3.2 (Samsung SIII ) it's working properly. Ndk-stack shows  me error in libVuforia but the question is if this is my error or not. Can you explain if "single-core not supported" means failing app? Or only extended tracking won't be working?

br,

Adam

We don't have any announcement on this. I am not aware of any plans for single-core support for Extended tracking, at present.
