Scope In part 6, I rewrote the movie search app in MVVM using LiveData and ViewModel architectural components from Jetpack. The app looks good in portrait mode, but there is an issue when screen rotates which is due to what I call an incorrect use of LiveData in part 6. This was deliberately made to draw… Read More »
Introduction In part 4, I started with implementing my benchmark movie app in Model-View-ViewModel (MVVM) using RxJava and with no use of Google architecture components (part of Jetpack now). Part 5 is where I first used LiveData as an architecture component, where I showed how LiveData can be used as a simple lifecycle-aware alternative to RxJava for implementing… Read More »
Introduction In the last part, I wrote about Model-View-ViewModel (MVVM) and its structure, together with an implementation of the same sample movie search app I introduced in the first part of the series. As mentioned in part 4, MVVM is chosen by Google as the standard for writing android apps owing to its advantages over… Read More »
Why am I writing this? There are many explanations, tutorials, blog posts on architectural patterns in applications, mostly MVVM, MVP and MVC, but most of them are too hard to digest for one who is not much familiar with the subject. Someone who is new to app architecture might want to know how its choice… Read More »
What is MVVM architecture? Model-View-ViewModel (MVVM) is a successor of MVC, invented by Microsoft architects to apply event-driven programming to applications involving user interface (UI) (Here is the original article). Separation of concerns reaches its highest in this architecture, as the different parts of the architecture are completely separate and have minimum dependence on each… Read More »
Introduction In part 3 of my series on architectural patterns in android, I wrote about MVP along with a sample android app and showed how using it can lead to more scalable, maintainable and extendable code. There are two things about MVP I am not a fan of: larger number of lines of boilerplate code… Read More »
Previous parts: Part 1: introduction Part 2: MVC What is MVP architecture? In the previous part, I wrote about some pitfalls of the MVC architecture and attributed them to the fact that the Controller does not DIRECTLY pass the data to the View and informs the View to get it directly from the Model. Well,… Read More »
This is the second article of the series on android architecture. The first part outlines the content to be discussed in the series. What is MVC architecture? The model-view-controller (MVC) has been the traditional architectural pattern for developing applications having user interface. Even though as an android architecture for developing apps, it is not much popular… Read More »
Scope There are many ways of writing android applications especially for simpler cases, but how they compare to each other is a question of android architecture whose answer distinguishes developers. A beginner in android development might be able to build an application that meets the same functionality as that built by an experienced developer. It… Read More »
