How to get Context in Android MVVM ViewModel


I am trying to implement MVVM pattern in my android app. I have read that ViewModels should contain no android specific code (to make testing easier), however I need to use context for various things (getting resources from xml, initializing preferences, etc). What is the best way to do this? I saw that AndroidViewModel has a reference to the application context, however that contains android specific code so I'm not sure if that should be in the ViewModel. Also those tie into the Activity lifecycle events, but I am using dagger to manage the scope of components so I'm not sure how that would affect it. I am new to the MVVM pattern and Dagger so any help is appreciated!


Solution

  • What I ended up doing instead of having a Context directly in the ViewModel, I made provider classes such as ResourceProvider that would give me the resources I need, and I had those provider classes injected into my ViewModel
