MVP modeling is a crucial aspect that any Android native app needs to take into consideration. If your business already has an app, or you are planning to build one, it is important to consider the MVP pattern in parallel with the business logic of your app
Although the MVP pattern and the business logic might not seem related, there is a strong relationship. After all, having the right Model-View-Presenter architecture can have a positive impact on your bottom line. The MVP pattern has an important impact on your User Interface, and ultimately, this can make or break your app.
The Model-View-Presenter architecture is one of the many aspects that any Android app development project should consider in order to guarantee a powerful User Experience and User Interface. However, it is also useful in order to guarantee that your app scales and is easily maintained through easily automatable unit testing.
The right MVP pattern can help you save money throughout the development of your app, and it can help engage your users. If you want to understand why it is important that your business logic is in line with the technical aspects involved in building User Interfaces, this post is for you.
An Overview of MVP Modeling and Its Benefits
The Model-View-Presenter architecture, sometimes referred to as the MVP pattern, is widely used throughout many Android apps for a reason. It is a way to address the different aspects that need to be considered when developing a top mobile app. This includes aspects as technical as retrieving information from a database to allowing the user to type in something into the app. Ultimately, the MVP pattern is a useful way of thinking about User Interface programming while optimizing the code of your app for a smooth development process.
By using a Model-View-Presenter architecture, developers can easily focus on activities that add more value throughout the app development process, like unit testing. By separating the architecture of the app into the three components of the MVP pattern (the data model, the presenter class, and the view interface), they can focus on making unit testing easier thanks to automation tools. Unit testing is essential to guarantee the quality of your app, and it is an important part of any QA strategy.
Additionally, the MVP pattern can also be used as a way to facilitate your app’s scalability. This is possible thanks to the architecture of an MVP pattern that divides an app into different components with different functions, rather than having a single large class that can saturate your system with unnecessary requests.
The Model-View-Presenter model can also separate different aspects of an app to avoid writing code that can easily become illegible. When the architecture of an app is not right, the code can easily become overcomplicated. In practical terms, using the Model-View-Presenter means that your development team won’t need to go through large and unmanageable amounts of code. By dividing the architecture of your app’s code into the three components of the MVP pattern, the need to refactor the code will be substantially reduced. This is a great advantage as it can help minimize the costs and stay within the estimated duration times of your project.
Lastly, by adding a User Interface through the MVP pattern, your app will be able to separate its data from what the users can control. In other words, you will be restraining data access so that users can only interact with what you allow them to. This sounds like obvious, but it is essential for any properly built architecture.
Components of the Model-View-Presenter Architecture
The MVP pattern consists of three different elements or layers:
The Model
This is basically the component of the MVP pattern where the data lies, therefore it can be referred to as the data model. It contains all the information relevant to your business logic, and gives the system access to your different databases. However, keep in mind that, although it is in this element where the data requests are performed, the user never really interacts directly with the data.
The model component of the MVP pattern never gets to interact with the view component. It only interacts with the presenter class located in the presenter model, helping keep the data secure and out of reach for the average user.
The View
The view interface refers to the actual User Interface with which the user interacts. It displays the basic functionality of the app, and additionally displays data from requests performed by the user.
It is in this component where all that is related to the User Interface programming occurs. Although there is much more to an app than this, the user will tend to judge your app based on its UI, so make sure to design one that engages them.
The Presenter
The presenter model is the component of the MVP pattern that acts as a bridge between the view interface and the data model. It is referred to as the trigger, as it retrieves data requested by users, and at the same time displays and notifies the view model about the received data.
This is where the presenter class is found. The presenter class manages the interactions of an app with an MVP pattern.
Other Models
As mentioned above, the MVP pattern (Model-View-Presenter) is a common architecture model used to build User Interfaces for Android apps while optimizing the resources used to build your app. However, it isn’t the only one. There are other models like the Model-View-Controller, also known as the MVC pattern, and the Model-View-View-Model, known as the MVVM.
Depending on type of project you are working on, one model might be better than another. Also, keep in mind that even if you use an MVC pattern or an MVP pattern, they might have slight variations from their ideal versions depending on the business logic you are working with. This is particularly true for custom mobile app development projects.
If you want to choose the right architecture for your mobile app, make sure to find the right app development partner. They can help you implement MVP modeling successfully.
