java.lang.NullPointerException issue on version 4.2

Issue: I added the latest version: implementation 'com.github.matomo-org:matomo-sdk-android:4.2' And when I go to the main activity I get this error: FATAL EXCEPTION: main java.lang.NullPointerException: Attempt to invoke virtual method 'int java.lang.Integer.intValue()' on a null object reference at my.app..ui.MainActivity$$ExternalSyntheticLambda3.onChanged at androidx.lifecycle.LiveData.considerNotify(LiveData.java:133) at androidx.lifecycle.LiveData.dispatchingValue(LiveData.java:151) at androidx.lifecycle.LiveData.setValue(LiveData.java:309) at androidx.lifecycle.LiveData$1.run(LiveData.java:93) at android.os.Handler.handleCallback(Handler.java:942) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loopOnce(Looper.java:201) at android.os.Looper.loop(Looper.java:288) at android.app.ActivityThread.main(ActivityThread.java:7872) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:548) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:936)

On an older version: 4.1.4 (works good), I don't get this error. What could be the problem? I looked in the code and I didn't find a problem of " 'int java.lang.Integer.intValue()' on a null object reference"

I strongly recommend to check my.app..ui.MainActivity$$ExternalSyntheticLambda3.onChanged It's located locally in you code. Without your code I can do here nothing

I tried to find out more details about the error. I followed the next steps:

1. Run the application, everything is fine, no issues
2. Add the library to the gradle module file: implementation 'com.github.matomo-org:matomo-sdk-android:4.2'
3. Crash when opening the app, with the same error as above: java.lang.NullPointerException: Attempt to invoke virtual method 'int java.lang.Integer.intValue()' on a null object reference at my.app.ui.MainActivity$$ExternalSyntheticLambda3.onChanged(Unknown Source:6). "Unknown Source:6" line is this import about PackageManager: import android.content.pm.PackageManager . I use this import to verify some app permissions: exemple 1: checkSelfPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED exemple 2:

   override fun onRequestPermissionsResult(
       requestCode: Int,
       permissions: Array<String>,
       grantResults: IntArray
   ) {
       super.onRequestPermissionsResult(requestCode, permissions, grantResults)
       if (grantResults.isNotEmpty() && grantResults[0] == PackageManager.PERMISSION_GRANTED) {   
       }
   }
