Mobile application development defines a process of developing software for smartphones and personal digital assistants, typically for Android and iOS. The application can be pre-installed on the device, downloaded from a mobile app store, or accessed via a mobile web browser. The markup and programming languages used for mobile app development include Java, Swift, C#, and HTML5.
Building installable software modules, integrating back-end services like data access through an API, and testing the program on target devices are all steps in creating a mobile app.
