A Beginner’s guide to Mobile App Development

If you’re currently a beginner in the software or IT career then Mobile app development is a really good opportunity for you. It is the process of creating software applications that may run on a mobile/phone. A mobile application requires a network connection to work with remote computing devices or cloud computing.

Mobile app development is sort of a domain of Artificial Intelligence. With the increase in its usage, many developers seek to find a platform to develop mobile apps. They are the most feasible, easiest to use, and work remotely too. In fact, according to the latest developments in the cloud, mobile apps could also be developed on cloud servers now! Isn’t that a win-win situation? The developer just does basic coding and his product would be ready to be deployed on a mobile device.

The development process involves:

  • creating software that could be installed (code, binary, assets, etc.)
  • implementing backend services (data access with an API)
  • final testing of the apps on the target device

Device Platforms for Building Mobile Apps:

In the smartphone markets, there are two dominant platforms, namely- iOS and Android. The iOS platform is from Apple Inc. and the Android Platform is from Google.

The iOS platform ranges only operating system that powers Apple’s line of phones, while the Android platform is used by Google & other OEMs to build their phones.

The development under iOS or Android involves using different Software development kits and development toolchains. The developers build apps for millions of devices targeting both of these platforms.

Development Approaches for building Mobile Apps:

The development of mobile apps is mainly dominated by 4 different approaches. When a developer chooses a certain approach, he takes into account the user experience, computing resources, features that are required by the app, the budget, time targets, and resources required to maintain the app.

Native Applications Cross-Platform Applications Hybrid-Web Applications Progressive Web Applications
are written in the programming language and frameworks provided by the platform owner can be written in a variety of different programming languages and frameworks, but they are compiled into a native application running directly on the operating system of the device. 

are built with standard web technologies - such as JavaScript, CSS, and HTML5

 they are bundled as app installation packages. 

are web applications that utilize a set of browser capabilities to provide an 'app-like user experience.
run directly on the operating system of the device such as iOS and Android. are a type of Native Applications  work on a 'web container' which provides a browser runtime and a bridge for native device APIs via Apache Cordova.  offer an alternative approach to traditional mobile app development by skipping app store delivery and app installations.
PROS: Best runtime performance; direct access to device APIs  PROS: Single code base for multiple platforms;  easy to build and maintain your app

PROS: Shared code base between web and mobile apps;

Using web development skillset for building mobile apps

PROS: the same app is available both for web and mobile;

No installation required, accessible through a URL

CONS: Higher costs when building and maintaining your app; 

Multiple code-bases for each platform

CONS: depends on bridges and libraries for native device features;

Performance limitations due to bridging 

CONS: Lower performance compared to native apps;

Limited support for native device features

CONS:  Limited support for native device features;

 App capabilities depend on the browser in use

The development cycle for Mobile Apps:

The “FRONT-END “ and the “BACK-END” are the two components that are interlinked in the development of mobile apps.

A Beginner’s guide to Mobile App Development

1. The frontend development and the backend development process:

Over time, with the improvement in connectivity and network capabilities, the mobile apps became connected to the sources of data & information outside of the app too. With the ability to update their UI on their own and resolve queries using data resources, the apps became quite dynamic.

Thus, the frontend services now rely totally on the backend services, as they provide data to be consumed through the frontend. The frontend obtains the data from the backend using a variety of services like APIs. The mobile app development companies may procure their own API or use a third party to generate API for them.

2. Using Cloud Backend/Frontend Services:

If the developer is not so skilled in developing a backend infrastructure, he can take help from a cloud service provider. Or if he isn’t that much of a trained developer in frontend services, he can use the cloud frontend services too.

Companies leverage the advantage of the best mobile app development services when they don’t have time and effort to develop their own app. Even as a freelancer, developers join these types of companies offering development of mobile apps.

3. The Mobile App Frontend:

It is that part of the mobile app which the user experiences- the visual and the interactive part. There are various languages and technologies that are used to carry forward this frontend development. The frontend development need not necessarily be carried on by a single developer, instead, various skilled people could contribute to it.

Some examples are Graphic Designers (responsible for creating visual elements like icons or backgrounds), UI/UX experts (layout of the components, interaction with the user), or engineers.

Regardless of all the development in the frontend, there is a responsibility on the people to interact with backend development services too. This helps to retrieve data and update it too. These backend services are accessed through APIs.

For example, the developer wants to access the database that contains information, he needs to get access to the backend services for this. He can use a specific API for utilizing the database information and location. An example of such an API is GraphQL API.

4. Mobile app Backend:

A reliable backend service is required to deliver a high-quality performance of mobile apps that retain users. There are many architectural designs too which the developers should consider, like which services could be built by them and which services could be borrowed from third-party providers.

They should build and maintain these backend services on their own and also leverage their data on cloud-based services to maintain infrastructure.
