As of 2.2.0. the lifecycle-extensions has been deprecated. Refer to Google Documentation.

This is the cut from the page:

The APIs in lifecycle-extensions have been deprecated. Instead, add dependencies for the specific Lifecycle artifacts you need.

The new libraries are:

// ViewModel and lifecycle support for java
implementation "androidx.lifecycle:lifecycle-viewmodel:${versions.lifecycle}"
implementation "androidx.lifecycle:lifecycle-livedata:${versions.lifecycle}"

// ViewModel and lifecycle support for kotlin
implementation "androidx.lifecycle:lifecycle-viewmodel-ktx:${versions.lifecycle}"
implementation "androidx.lifecycle:lifecycle-livedata-ktx:${versions.lifecycle}"

The new code for JAVA:

viewModel = new ViewModelProvider(this).get(MyViewModel.class);

Or for Kotlin:

viewModel = ViewModelProvider(this).get(MyViewModel::class.java)
