ZXing (a barcode scanner application) can't work #24

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 

1. Enable USB Camera support by following Jim's mail,
http://groups.google.com/group/0xlab-devel/browse_thread/thread/e9316dc1b60b5700
2. Build and install ZXing from
http://zxing.googlecode.com/files/ZXing-1.3.zip 
3. Launch ZXing and sooner enough the application would stop due to an
ArrayIndexOutOfBoundsException.

The logcat log is as below:

Thanks jserv's hint, The java application can only takes the frame as the same 
format
as the Camera HAL layer posts.
As Android Issue 823 points, this is still an unreolved issue in cupcake.

Right now on our device, Camere service posts frames in RGB format for showing 
on the
framebuffer, that's why zxing can't decode in any way. If changing to post 
frames in
yuv420 format, the barcode decoding can function but the preview showing on the
screen is yuv420 format data. 

So it looks like we can say this issue depends on hardware or depends on Android
Issue 823.

0xdroid has a modified copy of ZXing:
    http://gitorious.org/0xdroid/packages_apps_barcodescanner

It is expected to resolve the issue.  Confirmed?

Yes, more than that ZXing should work by the commit
http://gitorious.org/0xdroid/hardware_omap3_camera/commit/bb4a2a3abbe2bbc1886e8b
74a32c7af41f585c12

Change to Fixed.
