I replaced this line
"viewModel = (activity as NewsActivity).viewModel"
from every fragment with this

"val newsRepository = NewsRepository(ArticleDatabase(requireContext()))
val vmProviderFactory = NewsVMProviderFactory(newsRepository)
viewModel = ViewModelProvider(this, vmProviderFactory).get(NewsViewModel::class.java)
"
and it worked.

But I have doubt why this line not working viewModel = (activity as NewsActivity).viewModel"

`Hi guys, the solution is quite simple...

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)

    val newsRepository = NewsRepository(ArticleDatabase(this))
    val viewModelProviderFactory = NewsViewModelProviderFactory(newsRepository)
    viewModel = ViewModelProvider(this, viewModelProviderFactory).get(NewsViewModel::class.java)

    setContentView(R.layout.activity_news)
    bottomNavigationView.setupWithNavController(newsNavHostFragment.findNavController())

}

`

The view must be created after the ViewModel setup, since every fragment will be refering the NewsActivity.

That will do the trick for sure.

Don't use FrameLayout
FrameLayout's lifecycle management is poor and causes strange behavior.
In the above case, the problem occurs because BreakingNewsFragment onViewCreated life cycle occurs before News Activity onCreate.

So change it like this

activity_news.xml

    <androidx.fragment.app.FragmentContainerView
        android:id="@+id/newsNavHostFragment"
        android:name="androidx.navigation.fragment.NavHostFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:defaultNavHost="true"
        app:navGraph="@navigation/news_nav_graph" />

NewsActivity

class NewsActivity : AppCompatActivity() {

lateinit var viewModel: NewsViewModel
override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_news)

    val newsRepository = NewsRepository(ArticleDatabase(this))
    val viewModelProviderFactory = NewsViewModelProviderFactory(newsRepository)

    viewModel = ViewModelProvider(this, viewModelProviderFactory)[NewsViewModel::class.java]

    val navHostFragment = supportFragmentManager.findFragmentById(R.id.newsNavHostFragment)
    val navController: NavController = navHostFragment!!.findNavController()

    NavigationUI.setupWithNavController(bottomNavigationView, navController)

}

}

androidx.fragment.app.FragmentContainerView is a part of the AndroidX library that improved the shortcomings of FrameLayout.
