如何修复 viewBinding { enabled true } 中未发生的错误 buildFeatures { viewBinding = true }

Question

I have just started using android development and trying to use Room library. Since yesterday I am facing this warning message that occurs when I import databinding on my MainActivity.kt

unresolved reference: databinding

It just runs fine when I input the ActivityMainBinding class

I was using android Gradle plugin version 4.1.2, so at the first I use buildFeatures { viewBinding = true } to migrate from kotlin synthetics and then when I try to import databinding to my MainActivity.kt the unresolved problem occur

so I try to use the older version of Binding viewBinding { enabled true } and it fix this issue

The problem is the older version of viewbinding will no longer support to android studio version 5

I want to know how to fix this issue, any clue?

}

Update

when I use the older version of viewbinding, indeed it fixes the issue above But, when I try to run the Application this error occur

DSL element 'android.dataBinding.enabled' is obsolete and has been replaced with 'android.buildFeatures.dataBinding'.

add this your build.gradle

android {
buildFeatures {
     dataBinding = true
     viewBinding = true
}
}
