Control crashing since latest Android updates (Android 15)

[oaktechnology]

Within the last few days an app that has been working on Android and IOS for years and now all of a sudden Android crashes when scanning a QR code. It seems to do the call back and populate the barcode information but then crashes out around 90% of the time.

This doesn't seem to be problem with older versions of Android so wondering if something new is upsetting the Camera control.

I also see this error message in the Debug Output (although not sure if this showed previously or whether its just since the Android updates.

Has there been any other reports as our IOS version still seems to be working fine.

Kind Regards

@oaktechnology - were you able to find a solution for this? Happening in my apps too.

@WilliamWatterson86 for me the problem was that i was getting the best resolution available of the camera device, and when i started recording a video, i was getting this exact error.

The solution for my problem was to change my logic to get the best resolution and checking if it was lower thank 4k and the aspect ratio should be 16:9 too.

Try changing the resolution set in CameraView, respecting the aspect ratio of 16:9.

Thanks @ArthurVarela, I have actually switched altogether to BarcodeScanning.Native.Maui package. Seems to work well for me.
