In our project, Observables and LiveData are used for databinding and observed from Fragments/Activities. Would love to know if I have implemented them wrong, or learn why unsubscribing isn't necessary.

Unlike a regular observable, LiveData is lifecycle-aware, meaning it respects the lifecycle of other app components, such as activities, fragments, or services. This awareness ensures LiveData only updates app component observers that are in an active lifecycle state

08/16/2019, 3:32 PMThe data binding generated code is responsible for observing and unsubscribing its own observers. If you have your own observers, independent of data binding, you are responsible for unsubscribing those.
However, this does not have a lot to do with Kotlin.
