I just posted my latest debug build. You might give it a shot. I think this
is just yet another device bug but if it's anything like the Optimus bug
(ie camera fails on some preview sizes) this might happen to also work
around it.

Not sure then, it works OK on my tablet. If you can post any other info
like suspicious-looking info from the logs, that might be a start.

Not sure where to post this, but wanted to confirm that the
BarcodeScanner-debug.apk that was posted here DOES fix the issue with the
Optimus.

Yup, definitely, it selects the screen size rather than a higher
resolution, which works around the Optimus bug. It's a shame as otherwise
you could use a little more resolution for scanning on the Optimus, which
helps a bit.

Marking this as fixed since the 4.1 workaround happens to address this too.

There's no more info here though about the problem... I don't have a Galaxy
Tab but it works on other tablets so suspect it is yet another device bug.

I have a Galaxy Tab with the following configuration and the just released
Barcode Scanner 4.1 can't read any code:
Build number: FROYO.VJJM9
Kernel version: 2.6.32.9 root@SEP-52 #1
Firmware version: 2.2
Model Number: GT-P1000L
Note: Barcode Scanner 3.72 works well

Sometimes setting the preview size does not work on this device, even if
the chosen size appears to be valid. The solution I found was to re-read
the preview size from the camera API parameters when the preview image
callback is invoked, and to not assume that the size requested is still
being used.

I think there is a bug in 'CameraConfigurationManager' MAX_PREVIEW_PIXELS
constant,
changing the value from '854x480' to '1024x600' worked for my device.
I've attached a patch with that change.

That's definitely not a bug - it's supposed to limit the preview size so
you're not scanning more pixels than are useful to scan.

That's ok. But the given 'limit' does not work for Galaxy Tab

It has no preview mode smaller than that limit? then it will just default
to whatever the default is. In any event it should still roughly work.

Is there a list of such resolutions? It would help me to find the optimal
one.

Run the ZXingTest app and it can dump all the camera's parameters and
settings, including supported preview sizes.

Srown,
The supported preview sizes for my Galaxy Tab are the following (the full
dump is attached):
preview-size-values=800x600,1024x600,320x240
preview-size=800x600
We've tried with 'MAX_PREVIEW_PIXELS = 800x600' and it does'nt worked.
However, if I change the 'findBestPreviewSizeValue' method to return a
hardcoded 'Point(800,600)' it does work.

Are you using 4.1?
What size does it select, 800x600? (Look in the logs.) What is the size of
the screen? It will prefer a size that matches the screen's dimensions if
possible.
The preview size is mostly cosmetic. As long as it's a reasonably large
without being too large it will scan fine. I don't think there's an app
problem, but, the device could well have a problem with one of its own
preview modes. (Example, the LG Optimus V actually shows nothing if you
choose a non-default preview size!)

Here's the log:
I/CameraConfiguration(17310): Screen resolution: Point(1024, 600)
I/CameraConfiguration(17310): Supported preview sizes: 800x600 1024x600
320x240
I/CameraConfiguration(17310): Camera resolution: Point(320, 240)
I/CameraConfiguration(17310): Supported values: [off, on, auto, torch]
I/CameraConfiguration(17310): Settable value: off
The screen size is 1024x600 and it selects 320x240 as the preview size,
which is the only resolution that lies in the default range [320x240,
854x480]. The strange thing is that if I try to set 800x600 as the
MAXIMUM_VALUE it doesn't work, but if I force the preview size to be
800x600 it does work.

Comment #23 on issue 1159 by srowen: Latest barcode scanner on market will
I see, the only preview size small enough is 320x240, and that's quite low
resolution. The minimum is there just to accommodate small-screen devices;
480x320 is much better as a minimum in practice.
The complication too is that 320x240 gets chosen over 800x600 arbitrarily
since they're both the same aspect ratio. But 800x600 is probably the
better choice.
I can make the max 800x600 since that's probably fine as a maximum these
days. I can also adjust the logic to prefer the larger option.

This change is already released. The S3 chooses a high resolution now.
