Flash/LED button not doing anything

[sukulent]

Firstly, thanks for this app, I have tried many code readers but this one feels the best. Easy, clean, FOSS.

Just the flash button doesn't do anything. Which is kinda breaking as lighting is important when scanning.

I have motorola moto G54 power edition running android 13 and BinaryEye version 1.61.0

also the vibration do not work, but I guess that's fine
(tho maybe it could point somewhere?)

Oops seems like I made a duplicate of #234 and #300 .

But sadly, the issue is still here, I have not bumped into this problem in any other app.
is there any debugging I could do to help?

Thanks for reporting this anyway! It's still a mystery to me, unfortunately, as I was never able to reproduce this, and the code is pretty straight forward 🙈

So, to fix this, I would need to know what is going wrong, especially what parameters.flashMode is here, and if there is an exception here. In which case you should see a message.

I want to make one app someday and I found a bit of time, so I have cloned the repo and dipped my fingers into android studio debugger. So when I run debug, it installs it onto my phone and:

after tapping the flash button
parameters.flashMode = "off"
then it assigns "torch" to it so
parameters.flashMode = "torch"
then it successfully assigns the parameters to camera.parameters without exception
when I put into the debugger camera.parameters.flashMode it says it's "torch"
and the function returns with no flash what so ever 👀

Thanks a lot anyway! 👍

This is nevertheless helpful as it rules out obvious reasons! Still very strange, of course 🤔 Hm.

Also, the flashlight button gets greyed out while BinaryEye is open.

I know you haven't been able to replicate the issue but I hope that every small detail we can provide gets you closer to fixing this bug. In the end BinaryEye will continue to be my only barcode/qr scanner, so far I don't need to scan codes in absolute darkness.

@samthelion17 that is a feature of android, when something opens the camera through the api (aka the way the system makes hw available to apps), the flashlight is 'glued' to that, so you can't use that button, if I'm saying that right

It does not work for me too. I am using LineageOS GSI (TrebleDroid-based). It works fine in the other apps, Open Camera (by Mark Harman) for example.
