Different Mobile App Development Platforms

There are a plethora of app building platforms that create and develop apps without breaking the
bank. Mobile application development is a term used to denote the act or process by
which application software is developed for mobile devices, such as personal digital
assistants, enterprise digital assistants or mobile phones. These applications can be preinstalled
on phones during manufacturing platforms, or delivered as web applications using
server-side or client-side processing (e.g., JavaScript) to provide an “application-like” experience
within a Web browser. Application software developers also must consider a long array of screen
sizes, hardware specifications, and configurations because of intense competition in mobile
software and changes within each of the platforms. Mobile app development has been steadily
growing, in revenues and jobs created.

A 2013 analyst report estimates there are 529,000 direct app economy jobs within the EU 28
members, 60% of which are mobile app developers.

As part of the development process, mobile user interface (UI) design is also essential in the
creation of mobile apps. Mobile UI considers constraints, contexts, screen, input, and mobility as
outlines for design. The user is often the focus of interaction with their device, and the interface
entails components of both hardware and software. User input allows for the users to manipulate
a system, and device’s output allows the system to indicate the effects of the users’ manipulation.
Mobile UI design constraints include limited attention and form factors, such as a mobile
device’s screen size for a user’s hand(s). Mobile UI contexts signal cues from user activity, such
as location and scheduling that can be shown from user interactions within a mobile application.
Overall, mobile UI design’s goal is mainly for an understandable, user-friendly interface. The UI
of mobile apps should: consider users’ limited attention, minimize keystrokes, and be taskoriented
with a minimum set of functions. This functionality is supported by mobile enterprise
application platforms or integrated development environments (IDEs).

Mobile UIs, or front-ends, rely on mobile back-ends to support access to enterprise systems. The
mobile back-end facilitates data routing, security, authentication, authorization, working off-line,
and service orchestration. This functionality is supported by a mix of middleware components
including mobile application servers, mobile backend as a service (MBaaS), and service-oriented
architecture (SOA) infrastructure.

Mobile apps are developed for a certain platform, and the two most popular platforms today
are iOS and Android.

The iOS platform powers apps built for iPhone and iPad. To develop an app for iPhone or iPad,
you need to use the Objective-C coding language and the Cocoa framework. Android apps are
developed with the Java coding language and the Android Software Development Kit, which
runs on Mac, PC or Linux.

There are other mobile platforms such as Windows Phone, but iOS and Android are definitely
the most popular. Most training for Developing apps for mobile devices requires considering the
constraints and features of these devices. Mobile devices run on battery and have less
powerful processors than personal computers and also have more features such as location
detection and cameras. Developers also have to consider a wide array of screen sizes, hardware
specifications and configurations because of intense competition in mobile software and changes
within each of the platforms (although these issues can be overcome with mobile device
detection).

Mobile application development requires use of specialized integrated development
environments. Mobile apps are first tested within the development environment
using emulators and later subjected to field testing. Emulators provide an inexpensive way to test
applications on mobile phones to which developers may not have physical access.

Mobile user interface (UI) Design is also essential. Mobile UI considers constraints and contexts,
screen, input and mobility as outlines for design. The user is often the focus of interaction with
their device, and the interface entails components of both hardware and software. User input
allows for the users to manipulate a system, and device’s output allows the system to indicate the
effects of the users’ manipulation. Mobile UI design constraints include limited attention and
form factors, such as a mobile device’s screen size for a user’s hand. Mobile UI contexts signal
cues from user activity, such as location and scheduling that can be shown from user interactions
within a mobile application. Overall, mobile UI design’s goal is primarily for an understandable,
user-friendly interfaces.
