typo in build.grade

[Dreablin]

// Lifecycle + ViewModel & LiveData
implementation "androidx.lifecycle:lifecycle-viewmodel-ktx:$lifecycleVersion"
implementation "androidx.lifecycle:lifecycle-livedata-ktx:$lifecycleVersion"
implementation "android.lifecycle:lifecycle-common-java8:$lifecycleVersion"

Should be androidx in the last line?
I have compile time error without it:
Execution failed for task ':app:dataBindingMergeDependencyArtifactsDebug'.

Could not resolve all files for configuration ':app:debugCompileClasspath'.
Could not find android.lifecycle:lifecycle-common-java8:2.3.1.

Yes you are correct.
