java.lang.RuntimeException: Unable to start activity ComponentInfo{<package-name>/com.google.android.gms.auth.api.signin.internal.SignInHubActivity}

I have received numerous Crashlytics reports of an exception my app is throwing, but I have never seen this myself, and I am struggling to understand where it is coming from.
My running theory is that it is related to the Firebase Auth dependency I have - but that dependency isn't actively being used yet. There is a whole sign-up and sign-in flow that my production app has disabled. The only two instances of the library being used in production code is:
// Inside Activity.onCreate()
Firebase.auth.addAuthStateListener {
val user = it.currentUser
if (user != null) {
Firebase.analytics.setUserId(user.uid)
CoroutineScope(Dispatchers.IO).launch {
registerDeviceToken(applicationContext)
}
} else {
Firebase.analytics.setUserId(null)
Firebase.messaging.deleteToken()
}
}
and:
// Called from Activity.onStart()
fun hasPendingMagicLink(intent: Intent): Boolean {
val emailAddress = getMagicLinkEmailAddress()
return emailAddress != null
&& Firebase.auth.currentUser == null
&& Firebase.auth.isSignInWithEmailLink(intent.data.toString())
}
I have included the Crashlytics reports below.

Android Navigation findNavController when NavHost is not in Activity

I have an activity which holds FragmentContainerView. In the FragmentContainerView I have a NavHostFragment. I want to setupActionBarWithNavController in the NavHostFragment.
class MenuNavHostFragment : Fragment() {
private lateinit var navController: NavController
fun setup(activity: MainActivity) {
navController = Navigation.findNavController(activity, R.id.fragment_menu_nav_host)
NavigationUI.setupActionBarWithNavController(activity, navController)
}
in MainActivity.kt
private lateinit var menuNavHostFragment: MenuNavHostFragment
private fun setupNavigation() {
menuNavHostFragment = MenuNavHostFragment()
menuNavHostFragment.setup(this)
}
in fragment_menu_nav_host:
...
tools:context=".View.MenuNavHostFragment">
<fragment
android:id="#+id/fragment_menu_nav_host"
android:name="androidx.navigation.fragment.NavHostFragment"
...
Which results in the following error message: ID does not reference a View inside this Activity
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.bla.bla/com.bla.bla.View.MainActivity}: java.lang.IllegalArgumentException: ID does not reference a View inside this Activity

How do I solve this?

The fragment in which navHostFragment is defined has to be created before calling the Navigation.findNavController() method to avoid this exception.

IllegalStateException: Could not convert SemanticsComponentNode to a View

I have a very simple #Composable function that I am trying to use in my layout. However, it ends up throwing an IllegalStateException and I am unable to figure out what I'm missing here.
class RallyActivity : Activity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContent {
Greeting("Tom")
}
}
}
#Composable
fun Greeting(name: String) {
Text(
"Hello, $name",
TextStyle(fontSize = 48.0F)
)
}

Fixed this issue by wrapping the Greeting composable inside a CraneWrapper and a RallyTheme.
class RallyActivity : Activity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContent {
CraneWrapper {
RallyTheme {
Greeting("Tom")
}
}
}
}
}

val viewModel by lazy {
if (viewModelFactory != null)
ViewModelProviders.of(this, viewModelFactory).get(mViewModelClass)
else ViewModelProviders.of(this).get(mViewModelClass)
}
This code is placed in the BaseActivity to create Viewmodel.
Here is My BaseActivity.kt
abstract class BaseActivity<VM : ViewModel, DB : ViewDataBinding>(private val mViewModelClass: Class<VM>) : AppCompatBaseActivity() {
#LayoutRes
abstract fun getLayoutRes(): Int
abstract val viewModelFactory: ViewModelProvider.Factory?
val binding by lazy {

val viewModel by lazy {

else ViewModelProviders.of(this).get(mViewModelClass)
}

I am using Dagger2
I lost my 2 hrs in searching the solution. Stackoverflow is the last hope.

After a long research I got a solution.
I Simply needed to add public #Inject constructor in my ViewModel class
eg;
class FullScreenViewModel public #Inject constructor(application: Application) : BaseViewModel<Any?>(application) {}

"You must pass in a non null View" when trying to get Facebook profile picture to ImageView

I'm using Firebase Facebook auth and trying to fetch profile picture to menu ImageView tried everything but it says same thing.
This is the Code in HomeScreen.java that has menu in it, And my Login is in MainScreen.java if you need other codes please let me know.
public class HomeScreen extends AppCompatActivity {
private DrawerLayout mDrawerLayout;
private ActionBarDrawerToggle mToggle;
private Toolbar mToolbar;
private CircleImageView mProfile;
#Override
protected void onCreate(Bundle savedInstanceState) {
setTheme(R.style.MyNavTheme);
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home_screen);
mToolbar = (Toolbar) findViewById(R.id.nav_actionbar);
setSupportActionBar(mToolbar);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawerLayout);
mToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.string.opendrawer, R.string.closedrawer);
mDrawerLayout.addDrawerListener(mToggle);
mToggle.syncState();
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
/**-------------------Facebook Profile Picture-----------------------*/
mProfile = (CircleImageView) findViewById(R.id.ivProfile);
int dimensionPixelSize = getResources().getDimensionPixelSize(com.facebook.R.dimen.com_facebook_profilepictureview_preset_size_large);
Uri profilePictureUri= Profile.getCurrentProfile().getProfilePictureUri(dimensionPixelSize , dimensionPixelSize);
Glide.with(this).load(profilePictureUri)
.diskCacheStrategy(DiskCacheStrategy.SOURCE)
.into(mProfile);
}
