We have the same issue on the 3.0.0 beta.

Are there any steps how to reproduce it ? We have logs from prod, but couldn't reproduce it locally

MartinRobins commented 3 years ago

I have the same issue on multiple devices and multiple Android versions. I have yet to reproduce it deliberately, but according to the users it tends to happen mostly when the device orientation changes.

There are also multiple other reports of the same problem here within the issues list (#1003, #924) that have (up until I last looked) not been addressed other than to suggest the 3.x version(s) - all of which still display the same problem.

I also have this issue. Multiple devices and multiple crashes per day on each. One user has orientation locked and is still experiencing the crash. I am unable to reproduce it, seems random.

Is this product even supported anymore? I havn't seen any updates for a long time. I now also get this exact error but it is hard to replicate.

One way we where able to duplicate is: 1) Go to system settings > Apps > YourApp. From there remove your camera permissions. Or on a fresh install of app. 2) Start your app

At this point and before the scanner opens we would CheckAndRequestCameraPermissions using Xamarin.Essentials. If they have yet to Accept or Deny permissions it will prompt them to do so. Once they Accept we then would go and do our normal camera/scanner startup. At this point it would crash. if you would go in and try it again it would work being they already accepted the permissions.

Our solution was to add a Delay of 100 milliseconds after they accepted the permissions and before they open the camera. await Task.Delay(100);

So it appears for us that if the camera opens up to quickly after they accept the permissions it would fail. This was occuring on a Pixel with Android 11.

5 years this issue persists, and it's not acceptable for our applications to CRASHE violently in production :-( As nobody move... so I will.

Related Issues : #728 #924 #1011 (and maybe more ? I stopped my search here...)

A pull request https://github.com/Redth/ZXing.Net.Mobile/pull/1002 has been kindly submitted by @rdfordatascience-ops (thanks ;-)) but has never been merged, accepted or included in a new version... It's not a "clean" solution, but it's better than CRASHES.

So :

I forked this repo (https://github.com/Respawnsive/ZXing.Net.Mobile)
I've applied the PR 1002 :
- Just a "try-catch" block for not CRASHING our apps
- Apparently, it continues to works normaly even after an exception raised here... (@rdfordatascience-ops you can confirm ?)
I've deleted some target platforms (I don't have time to install all the SDKs required for platforms that nobody use ;-)) :
- Tizen
- MacOS
- Windows UAP
- (so I only keep .netStandard/Android/iOS
I build successfully, generate NuGetPackages and publish them :

https://www.nuget.org/packages/Respawnsive.ZXing.Net.Mobile/ https://www.nuget.org/packages/Respawnsive.ZXing.Net.Mobile.Forms/

-> 1 hour, that's all what it takes to me...

So I hope this will be usefull for some peoples... because the "real production world" is not focused on MAUI (not yet at least ;-)) Regards

I am also seeing this happening I haven't looked at causes at all but this IS a issue that needs looking into
