Mobile App Development: Quick Start Guide 

Mobile app development is a demanding career path due to the dynamic nature of the technology landscape and the ever-evolving user expectations. As the demand for innovative and user-friendly mobile applications continues to surge, developers face the challenge of staying abreast of rapidly changing frameworks, languages, and design principles. Additionally, the diversity of mobile platforms, such as iOS and Android, necessitates proficiency in multiple programming languages and development environments. The app market's competitive nature requires developers to possess technical skills and a keen understanding of user experience, market trends, and business strategies.  

Mobile apps are expected to generate over $935 billion in revenue in 2024. The Apple App Store has 1.95 million apps available for download. There are 2.86 million apps available for download on the Google Play Store. 22% of Millennial open an app 50+ times per day. 

What is mobile application development? 

• Mobile application development creates software applications for mobile devices such as smartphones, tablets, and other handheld devices. This field encompasses various activities, including designing, building, testing, and deploying mobile applications. 

• The development of mobile applications typically involves using specialized programming languages and development frameworks to create applications that can be installed and run on mobile devices.  

• These applications can leverage the unique features of mobile devices, such as touchscreens, cameras, GPS, accelerometers, and other sensors. 

• Several essential aspects to consider in mobile application development include user interface design, performance optimization, security, and compatibility with mobile platforms and devices. Developers must also consider the constraints of mobile devices, such as limited processing power, memory, and battery life when creating applications. 

Mobile application development can be categorized into two main approaches:  

• Native  
• Cross-platform development 

• Native development involves creating applications for a specific mobile platform, such as iOS or Android, using platform-specific programming languages and development tools.  

• Cross-platform development, on the other hand, involves creating applications that can run on multiple mobile platforms using a single codebase, often through frameworks like React Native, Xamarin, or Flutter. 

The mobile app development process typically involves several stages: 

•          Conceptualization 
•          Planning 
•          Design 
•          Development 
•          Testing 
•          Deployment,  
•          And ongoing maintenance and updates.  

It requires collaboration between developers, designers, and other stakeholders to create user-friendly, functional, and secure mobile applications that meet the needs and expectations of users. 

Choose a platform 

• Many application developers' teams choose to build Android applications, and it is their first attempt, too. Why did they choose Android first? Because 80 % of the smartphones around the world are Android. The Google Play Store has fewer restrictions than the Apple App Store. 

• On the other hand, the application developed for iOS mandates few crucial support, and user retention is typically higher for iOS applications. 

• Whatever the application, the demand is merely based on the user and target audience. For example, if you intended to design an application for your organization or employees-based applications, they must focus on the need, and it would support the platform they use. 

• You might have developed cross-platform apps that can work for iOS and Android. Or, if you design apps that are used for your intended customers that are intentionally designed for iPhones, then your priority would be iOS applications.  

• When developing your mobile applications, it's crucial to consider additional factors such as monetization strategies and expected user behavior. These aspects can be shaped by geographical and cultural factors, adding complexity to the development process. 

• Improve operational efficiency and strengthen security by incorporating the development platform with the device management tool. 

Develop for both Android and iOS: Native apps or hybrid apps? 

• Suppose you must develop a mobile application for Android and iOS operating systems. What would be the most effective software development approach? 

• Creating two native applications proves advantageous, as it enables the utilization of native APIs and programming languages specific to each operating system. This approach ensures robustness and is especially beneficial for enterprise-level applications, particularly those requiring substantial API interactions.

• Choosing to develop native applications one after the other, starting with Android, aligns with a common strategy often employed by independent app developers. Commencing the development of the complete application as a Minimum Viable Product (MVP) on the Android platform will likely be more successful. Following its initial release, you can convert and optimize the application for iOS.

• Debugging and rewriting the code in the native language and redesigning the front-end user interface are necessary. This is due to the significant differences in the functioning of the two operating systems, rendering cross-platform operations unfeasible. 

• Why not initiate the project from the ground up? Although direct code translation into a new programming language isn't feasible, a significant portion of the back end can be replicated for cross-platform compatibility. Frameworks, libraries, and third-party extensions frequently operate uniformly in both environments, enabling you to sidestep expensive overhauls. 

• An alternative is to adopt a hybrid approach, embracing a write-once-run-anywhere methodology. Hybrid apps employ a single codebase capable of operating on both platforms. These applications are usually coded using a universally recognized programming language like Java, JavaScript, HTML, or CSS. 

• Hybrid mobile application development is most effective for straightforward web applications, as it lacks access to the native APIs of the operating system. It is well-suited for relatively uncomplicated mobile applications, typically consisting of three or four pages and featuring limited functionality. 

Building for a mobile platform: 

• Whether you choose native or hybrid mobile application development, you will encounter one of the first challenges—working with relatively limited resources on mobile devices. Your target mobile device's processing capacity and memory are significantly less than desktop computers or enterprise servers. This presents a notable challenge, mainly if you are accustomed to the seemingly boundless resources available in conventional software development for web apps. Adjusting your goals for app design becomes imperative due to the constrained resources on the mobile platform. 

• During mobile application development, developers must focus on making their mobile app consume fewer resources than a typical desktop application. 

• Prioritizing an excellent user experience is crucial, especially regarding mobile app interfaces. The design should be more straightforward than desktop applications, focusing on essential functions. Additionally, the interface should be optimized for touch, allowing mobile users to navigate and input information easily without excessive typing. 

Examples of successful mobile apps in today's market 

When it comes to successful mobile apps in today's market, success can be measured in multiple ways, like downloads, user engagement, revenue, or cultural impact. Here are some examples that excel in different areas:

Join a developer program 

Joining a developer program is crucial for mobile app developers as it opens doors to a wealth of resources, support, and opportunities that can significantly enhance their app development journey. Developer programs, often provided by platforms like Apple, Google, or Microsoft, offer access to official software development kits (SDKs), APIs, and documentation, providing developers with the tools needed to create robust and feature-rich applications. Additionally, these programs offer valuable insights, updates on the latest industry trends, and forums for networking with fellow developers. The collaborative environment within these programs fosters continuous learning, helps in resolving challenges, and ultimately contributes to the success of mobile app developers in a rapidly evolving tech landscape.
