Existence of Mobile Application Development in Fast Changing Industry

Hello!

Change remains the only constant in the IT industry, and nowhere has this been more dramatic than in the mobile sector.

Let’s examine how the industry has evolved over the past two decades and what this means for mobile application development today.

Smartphones have transformed dramatically: from Nokia’s basic feature phones to BlackBerry’s enterprise-focused devices, and then to the revolutionary smartphones introduced by Google and Apple. Hardware capabilities have advanced steadily, with increases in RAM, processing power, and integrated components such as cameras, GPS, accelerometers, and fingerprint readers.

Over the years, numerous mobile operating systems and platforms have emerged from companies including Sun, Qualcomm, RIM, Microsoft, Google, and Apple — ranging from J2ME/BREW to BlackBerry OS, Android, iOS, and Windows Phone. Each platform offered distinct native APIs, development frameworks, and base programming languages: Java for J2ME, RIM, and Android; C++ for BREW; C#/C++ for Windows Phone; and Objective-C for iOS.

With the market fragmented across multiple platforms, developers and companies faced significant challenges in building applications for all systems. Supporting each platform required diverse skill sets, increasing both cost and time-to-market.

Hybrid applications — web-based solutions wrapped in native containers — were explored as an alternative, yet they often fell short in performance, user engagement, and full utilization of device hardware.

The emergence of bot platforms has since opened new possibilities for creating device- and platform-agnostic applications.

Over time, chatbots are expected to replace a substantial portion of traditional mobile apps, although current bot platforms remain limited in API coverage, features, and capabilities.

Given the diverse OS landscape, a well-considered mobile app design and development strategy is essential. An effective approach enables support for multiple operating systems and devices while maintaining strong performance and user engagement.

This article draws on extensive experience designing and developing games as well as consumer and enterprise-grade mobile applications across all the platforms mentioned. Individual developers and organizations planning to create mobile mobile applications may find these insights useful when evaluating the advantages and trade-offs of each strategy.

The following sections outline the evolution of major mobile platforms, the challenges they presented, and the design and development approaches adopted to address them.

Mid-2000s: The era of feature phones with J2ME/BREW applications

Between the mid-2000s and roughly 2004, BREW and J2ME games and applications dominated the market. Most feature phones supported either J2ME or BREW because users relied on basic handsets that required lightweight platforms.

Qualcomm’s BREW was built on C/C++, while J2ME (Java 2 Micro Edition) was a streamlined version of Java’s Standard Edition with a restricted API set designed for devices with limited hardware resources.

It was primarily used to create lightweight games and basic applications, such as those for personal information management, on feature phones with modest capabilities.

J2ME devices offered minimal access to system or hardware interfaces, and even when available, functionality was often unreliable. This restricted J2ME mainly to games rather than sophisticated consumer applications.

The challenges — limited hardware, restricted APIs, and lack of multitasking

1. Developing games or applications on J2ME was difficult due to constrained hardware. Many devices allowed a maximum JAR size of 64 KB and only 128 KB of RAM. Even the popular Nokia 6600 in 2005 supported just 1 MB of RAM for J2ME applications.

2. The limited API set permitted only very basic applications.

3. Multitasking was unavailable on most feature phones; J2ME applications paused when moved to the background.

Approaches to address small RAM and application size limits

1. Applications shipped with minimal embedded resources; additional assets were downloaded from the server on first launch and cached locally.

2. Only the portion of data or images required at any moment was loaded, with resources swapped as needed. For example, large character animation images were split into separate parts to stay within memory constraints.

3. Basic applications were built without rich APIs or multitasking support.

2005–2010: The BlackBerry era introduces the first true smartphones

Between 2005 and 2010, BlackBerry devices from RIM gained widespread popularity. BlackBerry offered the first smartphone platform discussed here, prized for its security and enterprise features. Its OS supported multitasking and initially featured trackwheel and trackpad navigation. Popular series included Curve, Pearl, and Storm.

BlackBerry provided a Java-based API set. Rich APIs and multitasking enabled sophisticated native business applications — something not feasible with J2ME. Developers could access device capabilities such as file operations, native email, phone, and SMS.

Applications from Reuters, Stitcher, OpenTable, and BroadWorks became possible on RIM. However, mobile web development remained limited due to weak JavaScript support.

The challenges

1. Small screens and single-pane views complicated UX design.

2. The native UI API set was complex and difficult to use for rich interfaces.

3. The older WebKit engine in the widely deployed 4.x OS series offered limited JavaScript capabilities, hindering mobile web development.

4. Static class verification made backward compatibility difficult when targeting newer OS versions.

Managing the challenges

1. Key modules were presented as home-screen options, followed by linear or tabbed navigation.

2. A reusable custom UI component library was created by extending standard containers and fields.

3. Native RIM applications remained the primary solution until the WebKit 2 engine arrived with OS 6.x/7.x in 2010–2012.

4. Backward compatibility was achieved by shipping a base application for the minimum supported OS version and loading additional binary files dynamically for newer OS versions when detected.

2010: How Android and iOS transformed the mobile industry

The launch of Android and iOS between 2008 and 2010 marked a major shift. These platforms ran on high-end smartphones that functioned as compact computers with powerful processors and extensive built-in hardware, including GPS, cameras, and accelerometers. Full-touch interfaces replaced physical keypads, improving usability and enabling advanced gesture recognition.

The challenge

With J2ME, BREW, and RIM already established, the arrival of Android and iOS created a highly fragmented market. Supporting multiple platforms with different APIs and languages increased costs and time-to-market while making consistent user experiences difficult.

Web and hybrid applications

Developers turned to HTML-based mobile web and hybrid solutions. Improved WebKit engines and HTML5 enabled cross-platform mobile sites, though adoption remained limited because users preferred native app icons and web apps could not fully access device hardware. Hybrid applications addressed these issues by wrapping web content in native containers and using bridge plugins for hardware access.

Hybrid versus native mobile applications

The choice between hybrid and native development depends on several factors:

1. Cost and time-to-market priorities

2. Target audience (consumer vs. internal)

3. Geographic scope and number of platforms to support

4. Application complexity and need for device hardware integration

2026: Android and iOS lead the mobile market

With continuous hardware improvements, both Android and iOS have become the leading choices for consumers. Growing user bases, developer adoption, and expanding app catalogs on the Play Store and App Store have solidified their dominant position in the global market.

Unlike BlackBerry, Android and iOS initially focused on end-user needs before expanding security and enterprise APIs. With the rise of BYOD policies, both platforms have also become preferred for business applications.

Simplified development tools and modern languages such as Swift have accelerated native app creation, effectively resolving the earlier cost and time-to-market challenges associated with supporting multiple platforms.

The challenge of app overload on mobile devices

Developers continue to release separate Android and iOS applications for narrow functions, resulting in device storage being crowded with numerous apps.

The future: Bot platforms and focused mobile applications

Today, most mobile users remain constantly connected to messaging channels such as WhatsApp, Facebook Messenger, or platform-specific services like iMessage. This engagement has prompted companies including Facebook and Slack to develop bot platforms that allow businesses to create chatbots reaching customers directly on these channels. Apple’s iMessage and Google’s Allo have also introduced bot capabilities.

Bot platforms enable businesses to maintain a presence on the channels where users spend the majority of their time. Chatbots appear as ordinary contacts, eliminating the need for separate apps for every function. Because they are device- and platform-agnostic, they offer broad reach.

Although still maturing, bot platforms are expected to handle routine tasks, while native Android and iOS applications will continue to serve specialized, high-performance requirements that benefit from direct hardware access, such as secure banking apps using fingerprint authentication or location-based services.
