It's wired that the layout works on my Android 9 phone and emulator.

I've updated the compile and target SDK version of the library to 28 in version 1.1.9. Please give it a try.

implementation 'com.nex3z:toggle-button-group:1.1.9'

thank for your try. but it still has error

[nex3z]

Looks like the exception comes from RoundedCornerLayout. There is a related issue and solution.

WOW, that was my mistake, sorry and thank you for your help.
