**[6APPDEV]** ***WEEK 1*** INTRODUCTION TO MOBILE PROGRAMMING ***PROGRAMMING AND SCRIPTING***\ As a tool for application development **PROGRAMMING** - Used to build full-fledged applications, systems, or software with complex functionalities. - Examples: Java, C++, C\#, Swift, Kotlin. **SCRIPTING** - Generally used for automating tasks, gluing together components, or adding functionality to existing systems. - Examples: Python, JavaScript, Bash, Perl, Ruby **INTEGRATED DEVELOPMENT ENVIRONMENT (IDE)** - An IDE typically consists of a code editor, compiler, debugger, and a GUI builder. **SOFTWARE DEVELOPMENT** - The process of designing, creating, testing, and maintaining software applications or systems. - It involves a series of steps, from understanding user requirements to deploying a fully functional product. **SOFTWARE DEVELOPMENT LIFE CYCLE** - The Software Development Life Cycle (SDLC) is a systematic process used by software developers and project managers to design, develop, and test high-quality software. - The goal of SDLC is to produce software that meets or exceeds customer expectations, is completed within time and cost estimates, and is efficient and maintainable. - - **ANALYSIS** - Understand and document the needs of the users or stakeholders. - **SYSTEM DESIGN** - Plan the architecture and design of the software system. - **IMPLEMENTATION (CODING/DEVELOPMENT)** - Write the actual code that implements the design. - **TESTING** - Ensure the software is bug-free and meets the specified requirements. - **DEPLOYMENT** - Make the software available for use. - **MAINTENANCE AND UPDATES** - Keep the software running smoothly and updated. - ***ROLE DESIGNATION***\ In team development **PRODUCT OWNER** - Also known as the client. - Sets the vision of what the software should do and how it looks. - The person responsible for determining the needs of the end users. - The client is also the one to set the standards and other project specifications. **PROJECT MANAGER** - Oversees the planning, execution, and completion of the project. - Develop the project plan, including timelines, resource allocation, and budget management. - Track the project's progress against milestones and adjust plans as necessary to meet deadlines. - Provide regular updates to stakeholders on the project's status, including any issues or changes. **SOFTWARE ARCHITECT** - A highly skilled software developer who designs the technical standards of the whole development lifecycle. - Choose appropriate technologies, frameworks, and tools that align with the project requirements. **DEVELOPER** - Write clean, efficient, and maintainable code according to the design specifications. - Identify and fix bugs and performance issues in the codebase. - Work closely with other developers, designers, and QA analysts to ensure seamless integration of Components. **UX DESIGNER** - Conduct research to understand user needs, preferences, and behaviors. - Ensure that end users have a positive experience using the software. - They check the functionalities if it's user-friendly and easy to navigate. - Work closely with developers to ensure the design is implemented correctly and maintains the intended user experience. **QA ANALYST** - Ensures that the software meets the required quality standards before release. - Develop test plans, test cases, and test scripts to cover all aspects of the software. - Perform manual testing and create automated tests to validate the functionality, performance, and security of the software. **PROTOTYPING METHODOLOGY** - **Prototyping** is a software development methodology in which a preliminary version of the system, known as a prototype, is created to visualize and experiment with the system's design and functionality. ***WEEK 2*** **ANDROID PROGRAMMING**\ Overview **WHAT IS ANDROID?** -
