Scanning is not working on Android while upgrading to 4.0.1

[lekhaiphtech]

When I upgraded to latest 4.0.1, scanning stops working on Android device and on iOS device its working fine. Scanning was working perfectly when I was using 3.0.1 version.

hmm interesting, thanks for the report. I might not have time to look into this until the weekend, so until then it might be worth staying on 3.0.0.

I hacked a quick fix for this issue that can be seen here.

Just a case of moving where we close the image. There's a lot of image/frame 'close' handing logic in that class. Not sure whether all of it is now necessary, but left it alone and walked backwards slowly 😉

I have the same issue, but only on devices running the Android 13. Like my Pixel 6 Pro.

Sorry, I've been completely swamped. No promises but I'm going to try to look into this soon. And yeah the image/frame logic is somewhat atrocious haha

@SoftWyer Not sure of the implications but for my specific use case (Xiaomi Redmi 8 and 9) it seems to work. Thank you!

I also had to add this to [email protected] build.gradle file to be able to build with your patch:

android {
    // ...
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
    // ...
}

otherwise I would get an error: lambda expressions not supported at this language level

We have the same issue on v4.0.1. I'm currently using the fork below as a workaround, but this is far from ideal. I hope this issue can be resolved in this library :)

Sorry for the ... long... delay on this. I'm putting on a version today which should fix that issue.

[rvanderlinden]

I can confirm this issue has been resolved in v4.1.0 👍

Thank you @rmtmckenzie!
