Thanks in advance!

[infotoni]

Ok I think I have solution. I added in gradle below implementation: ('com.roomorama:caldroid:3.0.1') this { exclude group: 'com.android.support' }

gradle write like this:

implementation ('com.roomorama:caldroid:3.0.1')
{
        exclude group: 'com.android.support'
}

Thanks for the workaround infotoni.

FYI appcompat will not be included in API 29+
