if inject other class is not problem

@champChayangkoon I'm fairly certain you're hitting this issue: #900 (comment). Would suggest reading that thread and using the advice there for working around this

[Chang-Eric]

I think the above is right and this is an @JvmSuppressWildcards issue.

[maozonghong]

@champChayangkoon do you solve this problem? I hava met the same problem?

[venukapavarapu]

I am facing the same issue.Please can you share the solution.I had already added @JvmSuppressWildcards even though I am facing the issue

Remove @Singleton on top of ViewModelFactory Class
move ViewModelModule into @ContributesAndroidInjector(modules = [MainModule::class,ViewModelModule ::class])

[kihaki]

Remove @singleton on top of ViewModelFactory Class
move ViewModelModule into @ContributesAndroidInjector(modules = [MainModule::class,ViewModelModule ::class])

Right, but then the ViewModel Factory will not be singleton scoped and will be a separate instance every time, which defeats the purpose.

Any solution ?
