Robust infrastructure is necessary, particularly when we are developing or constructing a mobile app. As time passes, business enterprises focus on building apps for reaching out to the targeted audience. It makes for a tough competition. According to Statista, 2.1 million apps are available on the Google Play store, and 1.8 million apps are available on the Apple app store. Talking about mobile app revenue, the global mobile app revenue is projected to be $189 million by the end of 2020.

It looks like the competition is strong and not allows each of them to reach the target. To succeed in this battleground, it is necessary to choose a suitable mobile application architecture. The primary reason why most of the apps failed due to poor mobile application architecture is the lack of understanding in the mobile app construction and mobile app development procedure.

Mobile Application Architecture

In a layman’s language, mobile app architecture is understood as a set of techniques and patterns required to be followed for building a fully structured mobile application. These patterns and requirements are formed by following the vendor’s needs and industry standards in mind.

Mobile Application Architecture

In the essential form, the mobile application architecture includes a set of patterns and techniques followed by developers for constructing a fully structured mobile application. The particular elements of the android framework architecture are chosen based on the app’s characteristics and specifications.

What Makes a Good Mobile Application Architecture?

A good mobile software architecture guarantees that components have multiple responsibility layers. Good mobile application architectures are the ones that will require assumptions and good programming patterns like SOLID or KISS. 

Meeting all these conditions allows us to accelerate development and making future maintenance is much easier. In this way, it will save time and money. Nevertheless, wisely choose architecture and platform-specific technologies like swift for iOS or Kotlin for Android. It will be one of the best architectures for efficiently resolving complex business problems for mobile projects.

It also enables us to avoid many problems making the quirks of hybrid technologies. This could be used as a long-term solution to saving time and money. Good architecture must be so difficult as developers can apply it to platforms such as iOS or Android. Responsibility layer separation is one of the essential features of good architecture.

Multiple Layers of Mobile Application Architecture Design

Three-layer architecture is among the most popular multilayer architectures. The main three important layers are:

1. Presentation Layer

Attention is paid to the components of the user interface and UI processor components by the presentation layer. The principal focus of this layer is how the application will be presented to the end-users. While designing this layer, developers are assumed to discover the correct client type complaint with the infrastructure.

The presentation layer embraces UI components and UI process components. While discussing this layer, the mobile app developer should explain how the mobile app will present itself in front of the end-user. Developers should also decide important things like themes, fonts, colours, etc., at this stage.

2. Business Layer

This layer represents the core of the mobile app that presents functionalities. On the backend server and device, the business logic layer could be remotely disconnected from the smartphone app for load reduction.  This load is generated because of the limited resources available on mobile devices. The layer essentially focuses on the business front. The business logic layer includes workflows, business components, and entities beneath the hood.

3. Data Access Layer

This layer is constructed by the combination of data utilities, data access components, and service agents. The data access layer coincides with the application requirements and promotes secure data transactions. It is essential for designing this layer because it could scale in the future. It is the third stage of data as it includes data access components, data helpers, and service agents.

The other circumstances for creating this layer is selecting the correct data format and putting it in a strong validation technique. This way, we can protect our app from any invalid data input. Mobile app developers should generally focus on the decoupling of business logic from the presentation layer code.

Important Factors to be Considered While Developing Mobile App Architecture

Below are the important factors:

1. Determining the Device Type

Smartphones come in different categories, and this is the major thing that we need to keep in mind while developing mobile app architecture. The type of smartphone is usually decided by its operating systems on which they run on. As we already know that Android smartphones are different from iPhones, and these are two separate categories. It is also a crucial deciding factor before selecting the mobile app architecture. The other major device characteristics which should be considered by us are:

  1. Screen size and resolution
  2. CPU characteristics
  3. Memory
  4. Storage capacity
  5. Availability of development tool framework

We need to keep in our mind to determine the type of device before choosing the mobile application architecture.

2. Considering Bandwidth Scenarios

There could be times when internet connectivity is zero or very limited. In such cases, we should consider the bandwidth scenario or think about the local internet network of the demographic region. Plus the area where our targeted audience is. Sometimes, users are frustrated by the internet’s low speed, and they could eventually abandon the app. It leads to a spooler user experience. Hence it would help if we considered the worst possible internet network while developing the mobile app architecture.

3. Selecting the Optimal Navigation Method

The remarkable factor is the mobile app navigation method. But the needs and priorities of customers could be fulfilled only by choosing the optimal navigation method. Mobile app navigation plays an important part in the user interface. It is essential for going with an optimal navigation method for the app. To obtain an optimal one, we can choose from the list of navigation methods below:

  1. Single view
  2. Stacked division bar
  3. Scroll view
  4. Modular controller
  5. Gesture-based navigation
  6. Search driven navigation
  7. Tab controller

Guidelines should be followed to understand the requirements of the user by considering different scenarios.

4. Static User Interface

A confusing UI leads to the failure of an app. Users should be able to interact seamlessly with the app. It is essential to keep things simple. We should make sure that v we do not pour all our creativity into the user interface. Never forget the thumb rule, which is simply the best way for designing highly interactive and intuitive UI.

5. Real-Time Updates vs Push Notifications

While deciding the correct mobile software architecture, we should ask ourselves whether our users require real-time updates or push notifications. Real-time updates could be a compelling feature, but it could be an expensive Idea. This feature also drains the phone’s battery and data.


Mobile application architecture is considered the backbone of any mobile app that offers features, functionalities, and user experience. It is safe to say that android framework architecture is the chief and crucial step as it will take our app towards the path of success and help us expand our business.
