I using MVVM on my Android application, on ViewModel I have many observers (from data binding) like ObservableBoolean, ObservableField, I read that I can use LiveData/MutableLiveData instead this observers... What's the difference? I can replace all my data binding observers by LiveData/MutableLiveData?
eg:
replace:
val loading: ObservableBoolean = ObservableBoolean()
By:
val loading: MutableLiveData<Boolean> = MutableLiveData()

LiveData is an observable data holder class. 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.
Data Binding allows you to effortlessly communicate across views and data sources. This pattern is important for many Android designs, including model view ViewModel (MVVM), which is currently one of the most common Android architecture patterns.
ViewBinding vs DataBindingThe main advantages of viewbinding are speed and efficiency. It has a shorter build time because it avoids the overhead and performance issues associated with DataBinding due to annotation processors affecting DataBinding's build time.
Many times has passed and I learned a lot... Replace all Data Binding Observable by LiveData, because LiveData respect the Activity lifecycle and can be used in JetPack lib's, like Room, Coroutine...
