I would like to add to this question, whats the best way to show progress indicators that won't hog main thread

[Tim]

yeah, like something non-blocking or whatever is recommended by google

Expose UI state in a LiveData. You could define a sealed class having a Loading implementation, and show a ProgressBar if it is Loading, and hide it otherwise

another option is using something like facebook’s shimmer: https://github.com/facebook/shimmer-android or creating a similar placeholder view

@tseisel @Brian both perfect, thank you

I use a Lottie animation, our loading indicators are branded

I use a Resource (like [1] from Google examples) class which can hold both state (LOADING, ERROR, SUCCESS etc.) and data. Then I will return a LiveData<Resource<List>> and observe it. Once the LD delivers an update, I will check the state inside the resource and update the UI accordingly.
