Final answer:
Mobile application development is the process of creating software applications for mobile devices.
The key stages include planning and analysis, design, development and testing, deployment and distribution, and maintenance and updates.
Step-by-step explanation:
Mobile application development involves designing and building applications for operating systems like i_OS (used in i_Phones and i_Pads) or Android (used in a variety of mobile devices).
The key stages in mobile application development include:
1. Planning and Analysis: This stage involves identifying the goals and requirements of the application, conducting market research, and creating a project plan.
2. Design: In this stage, the visual and user interface design of the application is created. This includes wireframes, mockups, and prototypes.
3. Development and Testing: The actual coding of the application takes place in this stage. It involves programming languages like Java or Swift. Testing is also done to ensure the proper functioning and performance of the application.
4. Deployment and Distribution: Once the application is developed and tested, it is ready for deployment. This involves submitting the application to app stores, such as A_pple's App Store or G_oogle Play Store.
5. Maintenance and Updates: After the application is deployed, regular maintenance and updates are required to fix bugs, add new features, and ensure compatibility with new OS versions.
