App crashes with unknown errors after setting MinifyEnabled - Kotlin

After completion of my app, it keeps crashing on the very first screens when minify is enabled. The errors seem unrelated to the code written and nowhere to be found on the internet which could've solved the problem without asking this question.

Please check the logs and proguard config provided below and point out any solution if possible.

The error log (I've cut short the repeating part of the log):

No errors apart from these. Have I missed something in the rules?

Edit: I've checked again and again and I've stil not found any errors. The app works well without minifyenabled.

Solution

  • After getting no response here, I contacted one of my known senior guy and figured out a solution.

    I could've fixed it if I could see it in logcat which is why I asked this question. So, the solution was that instead of looking into the logcat provided by Android Studio, I should look into the logcat provided by ADB in a terminal. I was using no filter or keyword in Android studio's logcat, it was just not showing anything.

    So, I ran a command adb logcat | findstr "app_name" and I was able to see the issue in Zoom SDK because of proguard. findstr "app_name" is optional here to filter the log by app name because the log was huge and was hard to filter with adb logcat.
