Hello everybody,
I want to ask somethigns concerning the Autofocus features in Vuforia SDK.
Firstly i want to learn how the feature is decided to be functional ? Because on some devices that can do autofocus with their native camera apps, you cannot turn on the autofocus feature on ImageTargets
Secondly, i am using Nexus S for testing at the moment, and although on your release notes section its mentioned like that below, in practice it says the device doesnt support autofocus when i try to turn it on.
- Added new CONTINUOUS_AUTOFOCUS mode to QCAR and exposed it in samples via GUI
- Note:Continuous auto focus is only available on select Android devices, e.g. Galaxy Nexus S, Pantech Vega Race

Hi, Vuforia queries the underlying Android system to obtain information about the supported focus mode;
if the "continuous autofocus" does not work, you could try the "TRIGGER_AUTOFOCUS" mode, which will trigger an autofocus event once;

Hi,
So about my second question. It says as ,i wrote before , that Galaxy Nexus S has continuous autofocus, but my Nexus S cannot do that with ImageTargets.
So does it mean that my Nexus S has some hardware problems?
Autofocus on Android Devices
I would not think of a hardware problem;
rather, it could be that the device is perfectly capable of doing "autofocus", but does not support the "continous" mode; this means you can trigger an autofocus event, but this only works as "trigger" mode;
