Detailed Course Modules

Module 1: Foundations & Setup

• 1.1 Introduction to Android: History, Android OS architecture, and the ecosystem of devices.
• 1.2 Getting Started: Installing and configuring Android Studio (the official IDE), setting up the Android SDK, and creating an Android Virtual Device (emulator).
• 1.3 Your First App: Creating a “Hello World” project. Understanding the project structure (manifests, java, res directories).
• 1.4 Introduction to Kotlin: Why Kotlin is the preferred language for Android. Basic syntax, variables, data types, and control flow (if, when, for, while).

Module 2: Kotlin Fundamentals for Android

• 2.1 Functions: Defining and calling functions, parameters, and return types.
• 2.2 Object-Oriented Programming (OOP) in Kotlin: Classes, objects, properties, constructors (primary vs. secondary), inheritance (open keyword), and data classes.
• 2.3 Null Safety: Kotlin’s most important feature. Understanding nullable vs. non-nullable types, safe calls (?.), the elvis operator (?:), and the not-null assertion (!!).
• 2.4 Lambdas and Higher-Order Functions: Essential concepts for modern Android development and using the Android SDK effectively.

Module 3: Building User Interfaces (UI) with XML

• 3.1 Understanding Views and ViewGroups: Introduction to widgets (Button, TextView, EditText) and layouts (LinearLayout, ConstraintLayout).
• 3.2 Mastering ConstraintLayout: The most powerful and flexible layout. Using constraints, bias, chains, and guidelines to create responsive UIs for all screen sizes.
• 3.3 Resources and Theming: Using strings.xml, dimens.xml, colors.xml, and themes.xml to create maintainable and stylable apps. Introduction to Material Design principles.
• 3.4 Handling User Input: Click listeners and basic event handling.

Module 4: Activities, Intents, and the Activity Lifecycle

• 4.1 What is an Activity? The core component of an Android app.
• 4.2 The Activity Lifecycle: Deep dive into onCreate(), onStart(), onResume(), onPause(), onStop(), onDestroy(). Why understanding this is critical for avoiding crashes and saving resources.
• 4.3 Intents: Using explicit intents to navigate between activities. Using implicit intents to interact with other apps (e.g., open a web page, send an email).
• 4.4 Saving UI State: Handling configuration changes (like screen rotation) using ViewModel and SavedStateHandle.

Module 5: The Modern Toolkit: Jetpack Compose

• 5.1 Why Compose? Introduction to the modern declarative UI toolkit.
• 5.2 Composable Functions: Building UI with composable functions instead of XML.
• 5.3 State in Compose: The fundamental concept of state hoisting. Making your UI reactive and interactive.
• 5.4 Layouts in Compose: Using Column, Row, and Box to arrange elements.
• 5.5 Theming and Material Design 3 in Compose.
• Note: This module can be taught as a parallel path to XML or as a replacement, depending on the course’s focus. Industry is moving towards Compose.

Module 6: Navigation and App Architecture

• 6.1 Navigation Component: Android App Development Course in Visakhapatnam | Implementing navigation between destinations (fragments/composables) using a navigation graph, safe args, and the NavController.
• 6.2 Introduction to App Architecture (MVVM): Why architecture is important for maintainability and testability.
• 6.3 ViewModel: Designing UI-related data holders that survive configuration changes.
• 6.4 LiveData and StateFlow: Observable data holders that notify the UI when data changes.
• 6.5 Repository Pattern: Creating a single source of truth for data.

Module 7: Working with Data

• 7.1 Persisting Data with Room Database: The recommended ORM (Object Relational Mapper) for SQLite. Defining entities, Data Access Objects (DAOs), and databases.
• 7.2 Consuming Web Services: Retrofit & Coroutines: Making REST API calls using the Retrofit library and handling asynchronous operations with Kotlin Coroutines.
• 7.3 DataStore: A modern solution for storing simple key-value pairs, replacing SharedPreferences.

Module 8: Advanced Topics & Polish

• 8.1 Notifications: Android App Development Course in Visakhapatnam | Creating and managing notifications.
• 8.2 Permissions: Requesting runtime permissions (e.g., camera, location) gracefully.
• 8.3 WorkManager: Scheduling deferred, guaranteed background work.
• 8.4 Testing: Introduction to writing unit tests and UI tests.
• 8.5 Debugging: Using the Android Studio debugger and reading logcat.

Module 9: Publishing and Beyond

• 9.1 Preparing for Release: Generating a signed APK / Android App Bundle (AAB), versioning, and testing release builds.

• 9.3 Post-Launch: Monitoring vitals (crashes, performance) and managing user feedback.
• 9.4 Next Steps: Exploring other Google APIs (Maps, ML Kit, Firebase), architecture patterns like MVI, and dependency injection with Hilt.

Module 10: Capstone Project

• Android App Development Course in Visakhapatnam | Students conceive, design, code, and document a fully-functional app from scratch that incorporates multiple concepts from the course:
  • MVVM Architecture
  • Room Database or Retrofit
  • Modern UI (Compose or XML with Navigation Component)
  • Other features like notifications or WorkManager.
• The final deliverable is the source code on GitHub and a published app on the Play Store (or a ready-to-publish AAB).

Recommended Tools & Technologies

• Language: Kotlin
• IDE: Android Studio (Flamingo or latest version)
• UI Toolkit: Jetpack Compose (Modern) and/or View System (XML) (Legacy but still widely used)
• Architecture Components: ViewModel, LiveData/StateFlow, Room, DataStore, WorkManager, Navigation
• Networking: Retrofit + Kotlin Coroutines
• Version Control: Git & GitHub

Upon completion, students will be able to:

• Build robust, modern Android applications using Kotlin and Jetpack libraries.
• Design responsive and interactive user interfaces with both Jetpack Compose and the traditional View system (XML).
• Implement the Model-View-ViewModel (MVVM) architecture to create testable and maintainable code.
• Persist data locally using Room and fetch data from network sources using Retrofit.
• Manage app navigation gracefully using the Navigation Component.
• Handle background tasks efficiently with WorkManager and Coroutines.
• Debug applications effectively using Android Studio tools.
• Prepare and publish an app on the Google Play Store.
