Android & iOS Mobile App Development Bootcamp (API + SQL Server + App Store Deployment)

Course Description

Duration 10 days – 70 hrs

Overview

This hands-on, end-to-end bootcamp trains programmers to build production-ready mobile applications for both Android and iOS, including frontend UI, backend/API design, SQL Server data storage, and full deployment to Google Play Store and Apple App Store. Participants will develop a complete capstone app that follows enterprise patterns (auth, CRUD, validation, logging, error handling), integrates with REST APIs, stores data in a backend connected to Microsoft SQL Server, and ships release builds for both platforms.

Objectives

Build cross-platform mobile apps for Android and iOS using a single codebase.
Implement mobile frontend UI/UX, navigation, forms, validation, and reusable components.
Design and build a backend REST API (CRUD, authentication, error handling, logging).
Store and manage application data in MS SQL Server through the API layer.
Integrate the mobile app with REST APIs (auth tokens, pagination, retries, offline patterns).
Prepare and deploy apps to Google Play Console and Apple App Store/TestFlight using correct signing/versioning workflows.
Apply practical security and quality checks (basic OWASP, secure token storage, testing basics).

Target Audience

Software engineers / programmers tasked to build mobile apps
Web developers transitioning into mobile development
Backend developers who need mobile + deployment skills
Internal IT/product teams building enterprise apps integrated with MS SQL Server and APIs

Prerequisites

Programming fundamentals (functions, OOP basics, debugging)

Familiarity with JavaScript or TypeScript (preferred)

Basic understanding of HTTP/JSON and REST concepts

Familiarity with Git

Basic SQL querying concepts

Course Outline

Day 1 — Mobile Foundations + Dev Environment Setup

Mobile architectures: native vs cross-platform; choosing an enterprise approach
Tooling setup: Node.js, package managers, React Native CLI, Android Studio, emulators
iOS overview: Xcode, simulators, Apple dev account concepts
Project scaffolding, folder structure, coding standards
TypeScript refresh (types, interfaces, strict mode)
Git workflow for mobile teams (branching, commits, PR hygiene)

Lab: Create first app, run on Android emulator, basic screen + component.

Day 2 — UI Development (Frontend Design)

UI fundamentals: layout, responsive screens, spacing, typography
Reusable components (buttons, inputs, cards, modals)
Forms + validation patterns
UX patterns for enterprise apps (error states, empty states, loading skeletons)
Accessibility basics

Lab: Build Login screen + Dashboard UI with reusable components.

Day 3 — Navigation + State Management + App Architecture

Navigation: stack/tabs/drawers, deep links (overview)
App architecture: screens, services, repositories, models, configuration
State management strategy (practical patterns using Context/store)
Environment handling: dev/uat/prod configs
Logging and error boundary patterns

Lab: Multi-screen app with protected routes after login.

Day 4 — API Consumption (API Usage for Development)

REST API fundamentals for mobile
HTTP client setup, interceptors, headers, token injection
CRUD calls, error handling, retries/timeouts
Pagination, search/filter, file upload/download patterns (optional)
Offline-ready patterns (caching and basic sync strategies)

Lab: Consume a sample API: list/detail/create/edit flows with robust error handling.

Day 5 — Backend Design: Building REST APIs (Backend Design)

Choose one backend stack aligned with your org:

Option A: ASP.NET Core Web API (best fit for Microsoft environments)
Option B: Node.js (Express/NestJS)

Topics:

RESTful design: endpoints, DTOs, validation, status codes
Authentication approach (JWT)
Middleware: logging, exception handling, CORS
API documentation (Swagger/OpenAPI)

Lab: Build API endpoints for users + one business entity (CRUD) with validation.

Day 6 — SQL Server Integration (MS SQL via MS Server)

Architecture: Mobile App → API → SQL Server (why direct DB from mobile is avoided)
SQL Server schema design basics (tables, relationships, constraints)
Connecting API to SQL Server (ORM or parameterized queries)
Transactions, data integrity, concurrency basics
Performance basics: indexing, query optimization patterns
Audit fields: created_at/updated_at, soft delete

Lab: Persist CRUD to SQL Server; implement list/search with pagination.

Day 7 — Security + Enterprise Readiness

Secure storage for tokens (keychain/keystore approach)
Handling secrets & environment variables correctly
OWASP Mobile top risks (practical checklist)
API security basics: rate limiting concept, input validation, authZ
Data privacy considerations (PII handling, logs)

Lab: Add role-based access + secure token storage + API authorization checks.

Day 8 — Testing + Quality + Debugging

Unit testing basics for mobile (logic/services)
API testing using Postman collections
Basic integration testing strategy (what to test, when)
Debugging: logs, network inspection, crash triage
Performance tips: list virtualization, memoization, avoiding re-renders

Lab: Add 5–10 essential tests + Postman suite + fix performance issues.

Day 9 — Android Deployment (Google Play Store)

Release builds: versioning, build types, environment configs
Signing keys and secure handling
Build artifact: AAB generation
Google Play Console: app creation, internal testing track, rollout basics
Store listing essentials and compliance checklist

Lab: Generate signed Android release and upload to Play Console (test track).

Day 10 — iOS Deployment (Apple App Store) + Capstone Demo

Apple certificates, provisioning profiles, bundle IDs (clear guided walkthrough)
Xcode archive, signing, IPA build
TestFlight distribution for QA/UAT
App Store submission flow + common rejection reasons (high-level)
Final capstone demo: app walkthrough + architecture + deployment artifacts

Lab: Produce iOS build and distribute via TestFlight (or simulate if no Mac access).

Capstone Project (Built Throughout the Bootcamp)

A complete enterprise-style app, e.g., Internal Service Request / Ticketing / Inventory / Field Ops App, including:
