androidx.lifecycle:lifecycle-viewmodel-ktx
dependency is added to your project'sbuild.gradle
file. - Incorrect Import: Verify that you have imported the correct package for
ViewModelProvider
. It should beandroidx.lifecycle.ViewModelProvider
. - Outdated Dependency: Check if you are using an outdated version of the Android Jetpack libraries. Update to the latest stable version to resolve compatibility issues.
