Here in this post you are going to learn about Mobile Application Architecture which involves both devices i.e. Android and iOS applications Architecture.
In this era of technological advancement, mobile applications have become an integral part of our daily lives. Mobile apps meet a variety of purposes, from social networking to productivity tools. Behind the seamless user experience lies a well-thought-out architecture that ensures the app’s functionality, performance, and scalability. In this article, we will delve into the world of mobile application architecture and explore the key components that make it a success.
Firstly, lets learn about Android Application Architecture. Android and iOS architecture have lot of components.
# Understanding Mobile Application Architecture 📱
Mobile application architecture refers to the structure and design of a mobile app, including how its components interact and function together. It acts as a blueprint for the app’s development process and defines how different modules will communicate with each other. By understanding the architecture, developers can build an app that is robust, maintainable, and extensible.
# Types of Mobile Application Architectures 📱
There are several types of mobile application architectures, each with its own advantages and disadvantages. Let’s explore three prominent types:
2.1 Monolithic Architecture
Monolithic architecture is a traditional approach where all the app’s components are tightly integrated into a single unit. This type of architecture is simple to develop and deploy, making it suitable for small-scale applications. However, as the app grows, monolithic architecture may face challenges in maintaining and scaling, leading to potential performance bottlenecks.
2.2 Microservices Architecture
Microservices architecture is an approach where the app is divided into smaller, independent services, each responsible for specific functionalities. These services can be developed, deployed, and scaled independently, promoting flexibility and maintainability. Microservices are ideal for large and complex applications, as they allow teams to work on different services simultaneously, fostering faster development.
2.3 Serverless Architecture
Serverless architecture, also known as Function as a Service (FaaS), is a cloud-based approach where the app’s backend logic is outsourced to a cloud provider. Developers focus on writing code for individual functions, and the cloud provider manages the infrastructure. Serverless architecture offers cost efficiency and automatic scalability, as resources are allocated based on demand. However, it may not be suitable for all types of applications, especially those with specific requirements for backend control.
# Android Mobile Application Architecture 📱
In Android Architecture, firstly there are web services.
3.1 Web Services
Every mobile App need some kind of web service.As you cannot directly connect to the database from mobile application so we need a connection to do that.
So , here you will use web service as every mobile application needs web service which act as a mediator between backend, database and mobile application and will get data from web services.
Now how to bring data to your mobile application.So for that we need Service Access layer.
3.2 Service Access Layer
In an mobile application, you require to generate or build service access layer which always interact with your web services and bring the data at same time .It also send the data which is necessary to go back to database.
After getting data to service access layer how to send it back to database.So here we are using offline database. Basically the reason of using the offline database is because e have to make mobile work when even there is no network connection.
# Mobile App Architecture Layers
Mobile Application architecture consists of three basic layers-
- Presentation Layer
- Business Layer
- Data Layer
4.1 Data Layer
Data Layer will help you to bring the data from Service Access Layer and push it back to the offline database. For e.g. here we will use SQLite as offline database .
4.2 Presentation Layer
In Android App Architecture this layer consists of UI components. Presentation layer consist of Activities,Fragments,View Group. This layer is basically the user interface which is responsible for look and feel of the app.
Activity is just a screen.
It is a component. You can design the component and then no. of fragments can be placed on activities.
It is a collection of activities.
4.3 Business Layer
There should be some kind of communication between activities and the data layer because the data has to come to the screen to presented to the end user so that is why we need Business Layer.
So business layer will always build a bridge between presentation layer and data layer.
Also , you may need some files, images for presentation layer.
# Key Components of Mobile Application Architecture
A successful mobile app architecture relies on various key components. Understanding and integrating these components effectively are vital for creating a smooth user experience. Let’s explore them in detail:
5.1 User Interface Design
The user interface (UI) is the front-end part of the app that users interact with. A well-designed UI enhances user experience and engagement. It involves creating an intuitive layout, visual elements, and easy navigation. The UI design should be consistent across the app to provide a seamless user journey.
5.2 Backend Services
The backend of a mobile app handles data storage, processing, and business logic. It communicates with the frontend to deliver requested information and perform necessary operations. Choosing the right backend services and technologies is essential to ensure data security, scalability, and optimal performance.
5.3 Application Programming Interface (API) Integration
APIs allow various software applications to communicate and exchange data. Integrating APIs allows mobile apps to leverage external services, such as social media logins, payment gateways, or location services. Proper API integration ensures a seamless flow of data and functionality, enhancing the overall app experience.
5.4 Data Management
Data management involves storing, retrieving, and manipulating data within the app. Efficient data management is crucial for mobile apps that deal with large amounts of user-generated content. Implementing proper data storage mechanisms and backup strategies ensures data integrity and availability.
Factors Influencing Mobile Application Architecture Decisions
Choosing the right architecture for a mobile app depends on various factors that developers need to consider. Here are some critical factors that influence architecture decisions:
6.1 App Complexity
The complexity of the app and its future scalability play a vital role in architecture decisions. Small and simple apps may benefit from a monolithic approach, while large and complex apps may require the flexibility of microservices or serverless architecture.
Scalability is essential for apps that anticipate rapid growth in user base or data volume. Microservices and serverless architectures offer better scalability compared to monolithic ones.
Every mobile app must prioritize security. The chosen architecture should provide robust security measures to protect user data and prevent potential cyber-attacks.
The development budget can also influence architecture decisions. While serverless architecture might save costs on infrastructure, it may not be the most cost-effective option for all types of apps.
There are many libraries in an mobile application architecture. Firstly, you have to build security layer ,configuration related library, have to build simple classes to establish internet connectivity i.e. for network.
Third party libraries are came to use if you are using some audio ,videos. Payment gateways are also example of third party libraries.
Push Notifications 🔔
Push Notifications is very important part in any mobile application. Push Notifications are used because in an application there is a need to send the notifications from servers to the application so that the users will be notified and he will come back to the application.
Push Notifications are of two types :
- GCM (Google Cloud Messaging)
- FCM (Firebase Cloud Messaging)
GCM is a service is allows the message transfer from the server to the client application.
FCM is a platform which provides messages and push notifications for operating system i.e. iOS and Android and websites also.
9.iOS Architecture 📱
An iOS App architecture is same as android app architecture except some components which are different in both architecture.
In this we have web services , Service Access layer which is explained in android architecture.
In data layer , Service agents and data helpers which helps to bring the data to offline DB and to access the data from offline DB. The offline db has many options whether you can use SQLite or realm. Any of these databases can be used based on requirements.
Next you have UI layer in architecture. This layer has storyboard, some custom controls to build custom UI and have xib files in Presentation layer.
This is similar to the android or any application architecture.
If the architecture is correct you can solve so many mobile architecture problems and result in a effective and acceptable mobile application. Those architectures helps in increase in flexibility,maintainence and testability and modularity in an application. You are going to know about some of the architectures explained below:
It is one of the popular architectures. When we use this approach it have three layers which have different functionalities.These layers are View,Controller and Model. View manages UI elements and keeps an eye on model if there is any data change occur.Whereas Controller helps in handling user actions and it processes data using model and update UI. And Model according to business layer rules handles data control.
10.2 MVP(Model -View -Presenter)
This architecture is as same as MVC. In this you have Presenter instead of Controller. For any UI changes View is used and for data changes model is used. In this architecture Presenter handles user actions and it processes data using Model and renders UI based on model. If you compare this with MVC , in this architecture View and Model does not communicate directly.
