NewsLand Android App Project aims to be a good sample for learners and reference for developers which provides: Android Architectural Patterns (MVP - MVVM) Dependency Injection (Dagger2) Working with observers & observables (LiveData - RxJava)

Android Note App, Using Android Architecture Components.

Popular Movies App project for Udacity Android Developer Nanodegree. Integrated the Paging library, LiveData, ViewModel, DataBinding, Room, MVVM architecture and Repository pattern.

Dagger 2 is one of dependency injection framework in Android that can provide us dependencies in a particular class. It’s probably the most used dependency injection framework in Android development. Singleton annotation can be put in other component and as long as the component alive the singleton annotated object will alive as well.

WorkManager is the recommended solution for persistent work. Work is persistent when it remains scheduled through app restarts and system reboots. Because most background processing is best accomplished through persistent work, WorkManager is the primary recommended API for background processing.

Retrofit is type-safe HTTP client for Android and Java by Square, Inc. It is an open source library which simplifies HTTP communication by turning remote APIs into declarative, type-safe interfaces. It makes it relatively easy to retrieve and upload JSON (or other structured data) via a REST based webservice.

The Room persistence library provides an abstraction layer over SQLite to allow fluent database access while harnessing the full power of SQLite.

The Data Binding Library is a support library that allows you to bind UI components in your layouts to data sources in your app using a declarative format rather than programmatically.

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. Instead of viewmodel..observe and setting the value to view we can directly use in XML @{vm.obj}

Instead of using onclick listener for binding.buttton and calling the change() of ViewModel we can directly bind it in <data> tage where we create viewmodal obj and call the change() in button onClick attribute.

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.

This is the android app built using java and made in Android Studio. This app is made by taking into consideration of the "Android Architecture Components". This app mainly focuses on the CRUD operations i.e, this app will let you able to add, read, update, and delete the notes by using the Room database.

这是一个基于 Android Architecture Components构建的mvvm架构项目
