Please describe the issue

[goodibunakov]

I have to use BaseActivity in my project. I did:

class SplashActivity : BaseActivity<SplashViewModel>() {
    private val binding by viewBinding(ActivitySplashBinding::bind, R.id.container) 
}

abstract class BaseActivity<T : BaseActivityViewModel> : AppCompatActivity() {
     override fun onCreate(savedInstanceState: Bundle?) {
           super.onCreate(savedInstanceState)
     }
}

And received: Unable to start activity ComponentInfo{....SplashActivity}: java.lang.NullPointerException: activity.findViewById(viewBindingRootId) must not be null

You need to set content view before access to the viewbinding delegate
