brainsketchscan keeps stopping on android

While using Futronic finger print, it throws an error "BrainSketchScan keeps stopping" and exits the program on Android Pixel 4a phone. I tried using clear cache and storage etc., but it does not resolve the issue.

Why sometimes android studio doesn't print stacktrace in logcat

I use Retrofit 2.8.1 to make a network call. When I disable my network connection, the app crashes. But strangely I've got nothing about stack trace on logcat. Just says:
E/AndroidRunTime: FATAL EXEPTION: main
Process: ir.kaaveh.recyclerviewmvvm, PID: 31179
When I surround my network call with try/catch and use e.printStackTrace(), I find out that:
java.net.UnknownHostException: Unable to resolve host "www.omdbapi.com": No address associated with hostname
Why Android studio don't show me stack trace in this case? Usually, it tells you which line causes throw exception.

Error in Huawei phone. Fatal Exception: java.lang.NullPointerException at com.google.android.gms.ads.internal.video.exoplayer3.a.b

I only get errors on the huawei phone
Fatal Exception: java.lang.NullPointerException at com.google.android.gms.ads.internal.video.exoplayer3.a.b.
I'm not an intern. So I know what is the usual NullPointerException error. In my question, the error only occurs on 1 single device and can not find details in the crashlytics report. So if you can not provide a help answer, please do not flag or report duplicates when you do not know what it is.

AccessibilityNodeInfo ArrayIndexOutOfBoundsException

Using the Android Accessibility Service.
On Android 8.0 (only) I have a lot of crash with:

This Stacktrace doesn't contain any line from my own code.
I cannot reproduce it on my side and I have no idea on how to fix it. Do you?

any help would be great
I solved it!
It was because I was using java.awt.point in the android build. So I basically wrote a new point class, replace it, and then cleaned my project. Everything works now
