With the expansion of the Android ecosystem, Android platform solutions and libraries have made progress. Android app development companies use design patterns for architecture as it is essential to create robust, maintainable, and scalable mobile applications.

You have to follow these patterns during the development of complex Android applications as it becomes easier to maintain and update the app in the future. It helps in organizing the code in a structured way, and modifications can be done in the app without affecting the whole project. These patterns help in adding test cases and thoroughly testing the application.

Why is a good app architecture important?

Good architecture is essential in mobile app development as it defines the overall structure and organization of the mobile app. Mobile app development companies in Houston focus on choosing the best design patterns for development. It shows how good the relationship is between different components and modules.

The development process is made more efficient by providing developers with a clear knowledge of all the requirements of the app. So, the developers could choose the best move on implementing features and functionality and eventually contribute to a streamlined development workflow.

Clear and structured code is always chosen by the developers for work. Software can be easily maintained by organizing codes according to the design pattern.

Here are the commonly used design patterns and Android app architectures in app development.

MVC (Model View Controller) 

MVC is the most commonly used design pattern in mobile architecture. It separates an application into three layers:

· Model: It decides how to handle the data and business logic on how the data is changed and manipulated.

· View: It is responsible for the user interface where the visual structure of the data stored in the model is shown here.

· Controller: It acts as an intermediary between the model and view and handles the user requests and updates. In this model, the developers work independently on different parts of the pattern, and the work can be completed at a faster pace. It also enables multiple app developers to work on a project. 

MVP (Model view presenter)

MVP is an alternative to the MVC pattern where it offers an easy way to organize the code and build a solid, maintainable, and testable app. Here, the role of the presenter is the same as a controller in MVC. This makes the pattern popular in Android application development. 

· Model: This layer is used to store the data collected from the network or database of the application. 

· View: It is a UI layer providing a visual representation of data and tracking user action to inform the presenter.

· Presenter: It manages the communication between the model and views where data is accessed from the model and applies UI logic to decide the display content.

MVVM (Model-View – ViewModel)

With this preferable pattern of developers, the code can be maintained and organized easily for mobile app development categories. The limitations found in MVC and MVP patterns can be overcome with this pattern. Here, the graphic user interface is separated from the business logic. Three components of this mode are:

· Model: The model represents the data and business logic of the application. When compared to MVC architecture, the MVVM model is only responsible for business logic instead of handling both business and UI logic.

· View: The View layer observes only the view model, with the main focus on the UI elements and excluding business logic.

· ViewModel: It links the model and view layer. Data streams to the view are provided by this model. Different view models might be there in a single view. It handles UI logic and updates the view with model changes. These architectural patterns help separate the database and network layers and result in smoother development and maintenance.
