Let’s face it. It is difficult to stay ahead of the curve in the overcrowded Google Play. There, technology lends a helping hand. If you plan an Android app for your company, all you can do is selecting the right architectural pattern with an efficient decoupled system to excel. But then, it is difficult to choose the proper pattern and you need to consult mobile app development companies.
Here we are going to describe the two most popular Android app architecture patterns. They are known as MVC (Model-View-Controller) and MVP (Model-View-Pattern). But, before that, let’s go through the importance of good architecture for your business Android app. We will find the answer to the question- why does custom mobile app solution require an ideal architectural pattern?
Why Good Architecture is Necessary for Customized Android Application
The Android app project starts with the selection of app architecture. If one gets failed in picking the right architecture pattern chances are bright that they face the problems like
* Unit Testing becomes difficult because of a higher complexity of the code
* Developers may not keep track of the logic
* App maintenance and management become more difficult for other Android developers
On the other hand, the right or ideal architecture can offer the following benefits to your business app.
Though there are three major patterns for developing Android applications namely MVP (Model-View-Presenter), MVC (Model- View- Controller), and MVVM (Model-View-ViewModel). But, here we will keep the focus on MVP and MVC architecture patterns.
MVP (Model- View- Presenter) or Clean Architecture
The Clean Architecture comprises three layers:
Presentation- It is an outermost layer, which is responsible for the way of showing data to the app user. The MVP is a part of the presentation layer.
Domain- The core functions of the Android app are included in this layer that stays in the middle layer.
Data- It remains in the inner layer and responsible for the access of data.
MVP has quickly gained ground in the community of Android app developers. It is used for developing UI. It allows the separation of the Presentation layer from the logic. It takes care of every aspect ranging from the actual work of interface (backend) to its appearance (frontend). It is a UI pattern that can make the automated unit testing easy while providing the clean code. MVP is just a derivative of the MVC pattern, but it has gained more fame than MVC.
In Android app development, the Model is a data access layer like database API or a Remote Server API
It consists of components that handle tasks like generating, storing, exposing, and fetching the data
Above-mentioned functionalities are performed in the background as they are time-consuming and can block the main thread UI
* The View is a passive interface that displays data and sends user actions to Presenter
* On the Android platform, it is represented by View or Activity
* It contains the visual part of the app
* It has the UI but lacks any logic or knowledge of the data displayed on the interface
* It is between Model and View. It triggers business logic and enables ‘the View’ to update
* It receives data from the Model and shows the same in the View
* It interacts with the Model to fetch the data and transform it to update the View
It is fair to mention that MVP can readily fulfill the requirements of Android app developers, and therefore, it is a preferred choice.
MVC (Model-View-Controller) or Standard Android
The Standard Android is a default approach for Android app development. Here, the ‘Activity’ and ‘Fragment’ act as a ‘Controller’, and resources are a part of the ‘View’.
Now, the problem with the Standard Android is the ‘Controller’ part is very large, which makes its testing difficult for the Android app developers.
The Model is a data layer. It manages the business logic and handling the network.
It is a way of representing the data that is fetched from the Model. We can consider the View as the User Interface (UI) layer.
Basically, the Controller is the logic layer. It bridges the gap between the user and the Model. It gets updates from the user’s behavior and prompts the Model as per necessity.
The MVC pattern restricts the Android app development to some extent. Though it is a standard Android pattern, it fails to come up with a robust app that has a clear code. MVC makes the code more complicated thereby making the testing procedure more complex. The Android app developers cannot perform the unit test as well with MVC pattern. In other words, the MVC pattern fails to meet the developer’s requirements.
Reasons why MVC bring challenges for App Developers
* App development using the MVC pattern is challenging for two reasons.
* It changes the UI continuously
* It lacks flexibility as per the developer’s requirements
Also, in MVC pattern, the ‘Model’ is dominating and both the ‘View’ and the ‘Controller’ are dependent on it. The ‘Controller’ updates or sends the data to the ‘Model’ and the ‘View’ shows the data as directed by the ‘Model’.
After getting information about MVP and MVC, you would certainly like to know more about how to select the right pattern for your business app. We will state the key differences between the two patterns MVC and MVP to help you choose the right one for your Android-based business app.
Points that differentiate MVC and MVP
MVC Architecture Pattern
* ‘Controller’ is based on behaviors
* ‘Controller’ can be shared across views
* ‘Controller’ determines the view to display first
* Maintenance cost is high
MVP Architecture Pattern
* ‘View’ is loosely combined with the ‘Model’
* ‘Presenter’ binds the ‘Model’ to the ‘View’
* Unit testing is easier than MVC
* Maintenance cost is low
Why MVP has an edge over MVC
In a nutshell, MVP has the slight upper hand over MVC as it can break down your Android app into the modules. MVP enables the Android app developers to get rid of creating ‘View’ constantly. In other words, MVP can assist app developers to make ‘views’ reusable. When you hire Android app developers, MVP is preferable as it can assist you to get a scalable Android application at less cost as compared to MVC.
