error: no suitable method found for method ViewModelProviders.of(Fragment,Factory)
Trying to provde ViewModel via ViewModelProviers.of() to my activity.
My activity extends AppCompatActivity but I still see this error:
error: no suitable method found for
of(StartActivity,StartViewModelFactory) method
ViewModelProviders.of(Fragment,Factory) is not applicable (argument
mismatch; StartActivity cannot be converted to Fragment) method
ViewModelProviders.of(FragmentActivity,Factory) is not applicable
(argument mismatch; StartActivity cannot be converted to
FragmentActivity)
Dependency Injection is provided with Dagger 2. Below is my Activity class StartActivity:
public class StartActivity extends AppCompatActivity {
@Inject
StartViewModelFactory startViewModelFactory;
StartModelView startModelView;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
AndroidInjection.inject(this);
super.onCreate(savedInstanceState);
startModelView = ViewModelProviders.of(this, startViewModelFactory).
get(StartViewModel.class);
}
If I understand correctly you should be able to send in an activity in ViewModelProviders.of() method if they extend AppCompatActivity or Fragment. But I get this error. Any help would be appreciated.

you should be using
.get(StartModelView.class);
and not
.get(StartViewModelFactory.class);
the factory provided to of() is used by android to generate an instance of your ViewModel subclass

Thanks, That is true. I added it in my code & this question. But the problem is still there. What could it persists? Could it have something to do with dependency injection?

It looks like you were correct. There was also another underlying problem with my modelviewfactory. I get a "uses uncecked or unsafe operations" from this line@NonNull @Override public <T extends ViewModel> T create(@NonNull Class<T> modelClass) { return (T) new StartModelView(getAllWalletsInteractor); }DO you know why?

that's normal, it is the way generics work on java.

Should I add @SuppressWarning annotation to it?
