In the modern world of technology, an architectural pattern with an efficient decoupled system is recognized as a crucial virtue to any corporation. This is due to the fact that a decoupled system can lower the value of maintenance cost. It also helps android app developers to make instant modifications in the coding part without affecting the entire system.
Further, the decoupled system promotes parallel development. It can divide work among different android developers, which will cut down the development time.
Herein, we are going to explain the two most famous patterns of Android architecture. They are called as MVC (Model – View – Controller) and MVP (Model – View – Pattern).
Before figuring out which architectural pattern is the best, let’s have a look at some of the conditions as to why does an app needs a good architecture? What does an app get from an ideal architecture? And, the different types of architectural patterns.
One of the simplest answers is that everything should be planned in a proper way, and this is something, which is bound to happen when it comes to Android app development. In this way, if you are going to work on any Android project, then it needs to be done by choosing an app architecture first.
In case, if you would not choose the right one, then you could probably face the following problems during the app development process:
If you are planning on developing a high-quality Android application, check out the following points –
Choosing an ideal architecture does not take much time in order to change the logic in the coding part (if it would require in the future). Also, an ideal architecture provides features like ‘easy to add’ and ‘remove’ in the coding part. Hence, it reduces the cost of maintenance.
Currently, there are three major architecture patterns for Android applications, such as:
This is a default approach when it comes to architecting the Android apps. And, the ‘Activity’ is responsible to process the data and updating the views. Activity act as a “Controller” in MVC. However, there are some extra responsibilities as it should be part of the “View”.
The Problem with the Standard Android: The problem is faced by the Standard Android is that both “Fragment” and “Activity” have become large in sizes, and they are quite difficult to test by Android developers.
When it comes to Clean Architecture, it is commonly known as MVP (Model – View – Presenter). The Clean Architecture consists of three major layers –
a) Presentation Layer includes how the application shows the data to the user.
b) Domain Layer includes what are the core functions of the application?
c) Data Layer includes how the data can be accessed?
The Presentation layer sits as the outermost layer. The Domain layer sits in the middle layer. And, the Data Layer resides in the inner layer.
The ViewModel recovers the data from the “Model” when it is requested from the “View” through Android data framework. With Data-binding MVVM pattern, both “Activities” & “Fragments” have become lightweight. Moreover, to write unit tests for Android developers also becomes easy because of the “ViewModels” which are coupled from the view.
In this era, where the UI (User Interface) logic inclines to change more frequently than the business logic. Therefore, developers were finding out the way of separating user interface functionality.
A few years ago, Android developers started using MVC architectural pattern in the process of building the Android application. But the app was far from being the robust due to using MVC pattern. Robust was not only the hurdle faced by developers, but the code was not cleared.
We found two reasons for this problem –
In MVC, both the ‘Controller’ and the ‘View’ depend on the ‘Model’. The ‘Controller’ updates the data, and the ‘View’ gets the data.
All in whole, MVC is not meant to suffice developers’ needs. There are some reasons because of which developers abandoned the MVC:
– MVC makes the code more complicated for Android developers.
– For developers, it is impossible to perform the unit test on their own.
You might have several questions in your mind like:
– What is the best architecture pattern for Android applications?
– How can you apply that pattern in the most effective way?
One thing that you need to understand is that there is not a single architecture that can fulfill the project’s needs. This is due to the fact that every design pattern is abstract, plus its implementation also depends on specific requirements.
Therefore, Android developers can pick different architectures according to applications. Even though, in a complicated project, each module possesses its own structure.
When it comes to choosing between those architecture patterns, MVP is a strongly recommended in the Android application development. The definition is not always an interesting part, yet it is super important.
In general, the MVP pattern allows separating the presentation layer from the logic. It means that everything from how the interface works to how it represents on the screen. MVP is a user interface architectural pattern, which eases automated unit testing and it is responsible to provide clean code. An MVP is a derivative from the known MVC.
Numerous architectural patterns appeared, but MVP (Model View Presenter) can fulfill the complete requirements of Android developers.
MVP is one of the patterns, which Android community prefers at this time.
In Android, the application should be easily extensible and maintainable. Therefore, in order to maintain the level, it is important to define separated layers well. And, MVP makes things easier for developers and it makes the views independent of the data source.
Here are the key differences between MVC and MVP:
However, in order to separate interface from the logic is not at all easy in Android. MVP (Model – View – Presenter) makes easier to avoid hurdles for android developers. In large android projects, it is pivotal to organize the code well. If it would not achieve, then it is impossible to maintain and extend.
To close things up, MVP does a great job than MVC to breaking down your app in the modules.
In an MVP, when you build an app, which is based on Android framework, then there is no need to create the ‘View’ constantly. The objective of MVP is to make views reusable.
As a conclusion, it is possible to say that MVP (Model – View – Presenter) is highly recommended for Android developers to build up an agile and scalable android application with minimal cost as compared to MVC.
