    Unhappy Nokia N95 Problem with JSR 234 (Very urgent)

    Hi,

    We are using Zxing QR barcode decoder in our application which used JSR 234 for focus, but i am not able to decode any image with Nokia 95. Same code is working with Sony Ericsson's K790i.

    Is there any problem with JSR 234 implementation on Nokia N95?
    Is Zxing QR barcode decoder have some problems?

    Please reply ASAP.

    Thanks,
    Ashish Garg

    N95 does not support the Camera parts of AMMS, only music packages from AMMS are implemented

    Hi, this is Sean from the zxing project. Yes I seem to recall that JSR-234 APIs exist but the auto-focus methods have no effect. So this application is not able to take advantage of this feature, which really helps decoding. The camera is excellent, itself.

    And then I know this library doesn't do very well on blurry or out of focus images.

    If you just need a decoder for the N95, Nokia's own decoder is excellent, and super-fast as it is written in native code rather than Java. It seems able to use the auto-focus capability. I would highly recommend that for Nokias.

    Hi
    I encountered the very same problem (N95 with ZXing).
    Has anyone found any solutions in the past 6 months?

    This little issue of setting focus will force me to convert
    my entire app to python/c++ which aren't portable or
    use a very ugly hack involving a native server which will listen
    to a local socket and perform the focus.

    Hi Barak,

    and welcome to Forum Nokia Discussion Boards!

    Unfortunately, hartti's reply is still valid: so, the Camera part of AMMS is yet not implemented on Nokia devices. Without that, no Java ME focus-management solutions or workarounds are available.
