The progression by which an app is developed for mobile devices, such as personal digital assistants, enterprise digital assistants or mobile phones which can either be pre-installed on phones during manufacturing platforms, or delivered as web applications using server-side or client-side processing is in general referred to as mobile app development. Considering 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 application development is carried out taking into account these key factors. After careful designing and a systematic development the created mobile application is first subjected to various kinds of testing processes.
These mobile applications are tested within the development environment by making use of emulators, since emulators provide an inexpensive way to test applications on mobile phones to which developers may not have timely access. The testing is carried out using emulators like Google Android Emulator, Android SDK Emulator, Test iPhone, BlackBerry Simulator, Windows UI Automation, and so on. Once the application comes out successfully then it is subjected to field testing. After the effective testing and approval the developed application is ready for launch through its respective application store.
Developing apps for mobile devices requires an intelligent contemplating of the limitations and features of the targeted devices. Since most of the mobile devices operate on battery power and have less powerful processors, but have more features such as location detection and cameras a developer has to consider a wide range of allied configuration aspects and platforms on which it has to run. Mobile application development requires the contemplation of specialized integrated development environments and constraints like screen, input and so on as outlines for design. Since the users often emphasise on interaction with their device, and the interface entails modules of both hardware and software suitable derivatives are taken into account.
As user input allows the users to manipulate a system, and device's output allows the system to indicate the resultant effects, accurate statistics are first analysed and put into action. Form factors, such as a mobile device's screen size, mobile user interface and so on signals location and scheduling the mobile back-end facilitates data routing, security and authentication, authorization, working off-line and this functionality is reinforced by a mix of middleware components. All the same conditions for choosing a development platform usually encompasses the target mobile platforms, existing infrastructure and development skills while targeting more than one platform it is also imperative to think through the effect of the tool on the user experience. And since performance is another important key aspect, emphasis is placed on presentation and user satisfaction as well.
