问题 I have an application module, let's say "Test". The "Test" module depends on a sub-module B. Both enable databinding.

Below is sample code in Package B. package com.test.packageb open class MainActivity : AppCompatActivity() { lateinit var binding : ActivityMainBinding override fun onCreate(savedInstanceState: Bundle?)
