Should I use LiveData in repository?

Should I use LiveData in repository?

LiveData and Repositories Apart from the other points, LiveData is tied to the Android Lifecycle. This can be a great thing, especially when communicating between ViewModel and components like Activities or Fragments. The way LiveData is architected, observing it mostly makes sense from the UI layer.

What is LiveData in MVVM?

LiveData Overview Part of Android Jetpack. 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.

What is a repository in MVVM?

What is Repository in Android’s MVVM architecture? Repository is a class which purpose is to provide a clean API for accessing data. What that means is that the Repository can gather data from different data sources(different REST APIs, cache, local database storage) and it provides this data to the rest of the app.

Is LiveData deprecated?

LiveData is officially deprecated in kotlin-only apps.

When should you not use LiveData?

When NOT to Use LiveData

1. You need to use a lot of operators on data.
2. You don’t have UI interactions with data.
3. You have one-shot asynchronous operations.
4. You don’t need to persist cached data into UI.

Is flow better than LiveData?

Livedata is used to observe data without having any hazel to handle lifecycle problems. Whereas Kotlin flow is used for continuous data integration and it also simplified the asynchronous programming. First, it used livedata to transmit data from the database to UI. It solved most of the existing problems.

Is LiveData hot or cold?

In theory, one could interpret LiveData as a cold source, but its usage patterns point to a hot source, just like a BehaviorSubject in RxJava; LiveData remembers the last value and emits it first to new consumers. To signal to consumers, LiveData has protected methods setValue and postValue.

CAN A activity have multiple view models?

According to the open/closed principle, you should create three different ViewModel s. The complexity isn’t increased that much, and you are gaining the ability to move one ViewModel (or just reuse it) with the corresponding RecyclerView to the another Activity very easily.

Why use flow instead of LiveData?

Key Difference between LiveData & Kotlin Flow Livedata is used to observe data without having any hazel to handle lifecycle problems. With Flow as return-type, room created a new possibility of seamless data integration across the app between database and UI without writing any extra code.

Is Rxjava lifecycle aware?

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.
