TOPIC:

After a time without trying to solve this, I was able to find the main reason of the labelVisibiltyMode.
It has to do with this import

implementation 'com.google.android.material:material:1.5.0-alpha02'

It has a interface @LabelVisibiltyMode that's probably merged as part of the final values.xml file.
Maybe if we updated your project to use androidx, that would solve the problem. But we can't do this migration right now.
I tried and there's a lot of things to fix. We won't have the time and we need the the checkbox correction asap.
Can you guys show where's the fix in the code or maybe release the fix in a older version?
 

You shall copy natives .so libraries from the new package and overwrite files from jniLibs in your project's folder.

It shall be enough.

 

Thank you for the answer, it worked and the new version is running.
Just a little detail, when the size of the checkboxes its lower then 10pixels, it wont get marked.
Ill attach an documento with 2 checkboxes, 1 of them (left side size 10x8) wont working and the right one (size of 10x10) working pretty well.
