Android 11 Crash - Githubissues

Android 11 crash issue still persists. None of the solutions I tried worked.

Steps :

Run app in android emulator
Open QR page
and app crashed

Hi, sure

While this code works fine in most versions of ios and android (versions 12-13 I tried), it gives an error in android 11 version. I couldn't resolve.

Admin Scanner View :

you can also check error on errorBuilder argument

I guess no need to call .start() function on initState since autoStart is already set to true

I guess no need to call .start() function on initState since autoStart is already set to true

I wasn't calling when I first got the error, then I tried. But I can try again. I'm trying now.

I updated my code as below, but the error builder crashed with the same error without even working.

change error.toString() to error.errorDetails.message

change error.toString() to error.errorDetails.message

I updated the code as below. But it crashes again with the same error. I can't even see the error returning from Errorbuilder.

Code :

                      scanQRCode(barcode.barcodes[0].rawValue!);
                    }
                  },

Lost connection to device.

I'm not really sure if this can be related to this issue, actually I have an UMIDIGI F3 with Android 11 which, when it try to access to camera, miserably fail.

The code I use is almost the same from the examples, but I think in this case the issue is with the device itself.
