LiveData is part of Android Architecture Components released by Google. It is an Observable(it follows observer pattern) class that holds data of type that you specify. If you have worked with RxJava, it is similar to an Observable.Thereof, what is mutable live data in Android?
Android LiveData. LiveData is a part of the architecture patterns. It's basically a data holder that contains primitive/collection types. It's used for observing changes in the view and updating the view when it is ACTIVE.
One may also ask, what is mutable LiveData? LiveData is part of Android Architecture Components released by Google. It is an Observable(it follows observer pattern) class that holds data of type that you specify. LiveData takes in an observer and notifies it about data changes only when it is in STARTED or RESUMED state.
In this manner, what is MutableLiveData?
MutableLiveData is a subclass of LiveData which is used for some of it's properties (setValue/postValue) and using these properties we can easily notify the ui when onChange() is called.
How does LiveData work?
Basically, LiveData is an observable data holder. It lets the components in your app, usually the UI, observe LiveData objects for changes. This behavior prevents object leaking and ensures the app doesn't do more work than it should.
When should you not use LiveData?
When NOT to Use LiveData - You need to use a lot of operators on data.
- You don't have UI interactions with data.
- You have one-shot asynchronous operations.
- You don't need to persist cached data into UI.
What is live data?
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.What is Mvvm Android?
Model-View-ViewModel (ie MVVM) is a template of a client application architecture, proposed by John Gossman as an alternative to MVC and MVP patterns when using Data Binding technology. Its concept is to separate data presentation logic from business logic by moving it into particular class for a clear distinction.Is LiveData thread safe?
So, LiveData is immutable. MutableLiveData is LiveData which is mutable & thread-safe. So yes, the difference comes only by making postValue and setValue public.What is MediatorLiveData?
android.arch.lifecycle.MediatorLiveData<T> LiveData subclass which may observe other LiveData objects and react on OnChanged events from them. This class correctly propagates its active/inactive states down to source LiveData objects.What is observer in Android?
The Observer Pattern is a software design pattern that establishes a one-to-many dependency between objects. Anytime the state of one of the objects (the "subject" or "observable") changes, all of the other objects ("observers") that depend on it are notified.What is Android architecture?
Android architecture is a software stack of components to support a mobile device needs. Android software stack contains a Linux Kernel, collection of c/c++ libraries which is exposed through an application framework services, runtime and application.What is view model in ASP NET MVC?
ViewModel serves this purpose. View Model is a model class that can hold only those properties that is required for a view. It can also contains properties from more than one entities (tables) of the database. As the name suggests, this model is created specific to the View requirements.What is immutable in C#?
An immutable type, in the context of C#, is a type of object whose data cannot be changed after its creation. An immutable type sets the property or state of the object as read only because it cannot be modified after it is assigned during initialization. Immutable types provides higher security than mutable types.What is data binding in Android?
It is a part of android architecture components. Today data binding is a hot buzzword Android developers quite recently. It is a support library that allows us to bind the UI components in the layout to data resources and this is done in a declaration format rather than doing it programmatically.
