how do we show progress indicators in 2019? like the spinning circle

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

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. [1] https://github.com/android/architecture-components-samples/blob/master/GithubBrowserSample/app/src/main/java/com/android/example/github/vo/Resource.kt
