App developer course

Lesson 1 • Core Programming Concepts Review

Refreshes fundamental programming constructs required for app logic. Bridges prior coding knowledge to mobile-specific patterns.

Lesson 2 • Setting Up Your Development Environment

Guides installation and configuration of essential tools before writing any code. Ensures a consistent, error-free workspace from day one.

Lesson 3 • The App Development Ecosystem

Maps the mobile and desktop app landscape across platforms and distribution channels. Establishes shared vocabulary used throughout the course.

Lesson 1 • Platform Design Guidelines

Examines the human interface and material design standards for major platforms. Teaches learners to apply platform conventions rather than fight them.

Lesson 2 • Layout Systems and Responsive Design

Covers constraint-based, flex, and grid layout models for multi-screen support. Connects layout logic to real device size variations.

Lesson 3 • Typography, Colour, and Iconography

Applies visual design fundamentals to create readable, branded interfaces. Reinforces accessibility requirements tied to contrast and type scale.

Lesson 4 • Navigation Patterns and Information Architecture

Defines how users move through an app and how content is organised. Directly impacts usability and retention metrics.

Lesson 1 • State Management Fundamentals

Introduces how apps track and update data across components and screens. Lays the groundwork for scalable architecture in later chapters.

Lesson 2 • Event Handling and User Input

Covers gesture recognition, form validation, and input lifecycle management. Connects user actions to app logic reliably.

Lesson 3 • Asynchronous Programming Patterns

Explains callbacks, promises, and async/await for non-blocking operations. Essential for network calls and smooth UI performance.

Lesson 4 • Language Syntax and Data Structures

Deepens command of the target language's syntax and built-in data structures. Provides the coding fluency needed for all subsequent chapters.

Lesson 1 • File System and Media Storage

Manages files, images, and binary data stored on the device file system. Covers permissions and sandboxing constraints.

Lesson 2 • Key-Value and Preference Storage

Covers lightweight storage for settings and small data blobs. Appropriate for user preferences and session tokens.

Lesson 3 • Relational Databases on Device

Introduces embedded SQL databases for structured, queryable local data. Connects schema design to real app data models.

Lesson 1 • Making Network Requests in Code

Implements GET, POST, PUT, and DELETE calls using platform networking libraries. Ties async patterns from Chapter 3 to real API calls.

Lesson 2 • Authentication and Authorisation

Implements token-based and OAuth flows to secure API access. Covers secure token storage and refresh strategies.

Lesson 3 • Error Handling and Offline Support

Builds resilient apps that degrade gracefully without connectivity. Combines local storage from Chapter 4 with network state detection.

Lesson 4 • HTTP and REST Fundamentals

Explains the request-response cycle, HTTP methods, and status codes. Grounds all subsequent API work in protocol-level understanding.

Lesson 1 • Code Review and Refactoring Practices

Establishes team-level code quality processes and systematic refactoring techniques. Ensures architecture stays clean as features accumulate.

Lesson 2 • Dependency Injection and Inversion of Control

Decouples components to improve testability and flexibility. Introduces DI containers and manual injection techniques.

Lesson 3 • MVC, MVVM, and MVI Patterns

Compares the three dominant architectural patterns with concrete code examples. Enables informed pattern selection based on project needs.

Lesson 4 • Modularisation and Feature Layering

Splits large apps into independent modules with clear boundaries. Reduces build times and enables parallel team development.

Lesson 1 • Integration and Widget Testing

Tests interactions between components and verifies UI rendering correctness. Bridges unit tests and full end-to-end scenarios.

Lesson 2 • Continuous Integration and Delivery Pipelines

Automates build, test, and artifact generation on every code push. Reduces manual release overhead and enforces quality gates.

Lesson 3 • Crash Reporting and Monitoring

Integrates runtime error tracking and performance monitoring into production apps. Closes the feedback loop between release and fix.

Lesson 4 • End-to-End and UI Automation Testing

Automates full user flows on real devices and emulators. Catches regressions that unit tests cannot detect.

Lesson 1 • Beta Testing and Staged Rollouts

Distributes pre-release builds to testers and rolls out updates incrementally. Reduces risk of widespread issues at full launch.

Lesson 2 • App Store Optimisation

Improves discoverability through keyword research, ratings, and visual assets. Directly impacts organic download volume post-launch.

Lesson 3 • App Store Submission Process

Walks through the end-to-end submission workflow for major app stores. Covers metadata, screenshots, and review guidelines compliance.

Lesson 4 • Post-Launch Analytics and Iteration

Tracks retention, engagement, and funnel metrics to guide the next release cycle. Connects data insights to prioritised feature development.
