Why Take This Course?
With over 1 billion Android devices already activated, Android represents an incredible opportunity for developers.

As Android continues to grow beyond smartphones, it will become the brains behind invisible, ubiquitous cloud-connected computing. The skills you learn in this course will help you build awesome apps for smartphones and tablets today, and propel you towards exciting opportunities in Android's future.

By the end of this course, you’ll build a cloud-connected Android app, and understand the tools, principles, and patterns that underlie all Android development. You’ll understand the challenges associated with developing for the mobile environment (and how to overcome them), learn how to build a great user experience for Android devices, and apply this knowledge to your own projects.

Syllabus

### Lesson 1: Create Project Sunshine with a Simple UI (5-8 hrs)
Start by installing Android Studio, you’ll create your first project with a simple list-based user interface. You'll then build and deploy it to virtual and actual devices. You’ll also discover what makes mobile - and Android in particular - a unique environment for app development.

* Android Studio, Gradle, and debugging tools
* User Interface and Layout managers
* ListViews and Adapters

### Lesson 2: Connect Sunshine to the Cloud (8-10 hrs)
Replace the mock data with real weather data by connecting Sunshine up to an Internet back-end courtesy of the Open Weather Map API. You’ll learn how to add permissions to your app, initiate network I/O, and how to move time consuming tasks like network data transfers off the main UI thread.

* Threading and ASyncTask
* HTTP requests on web APIs
* Android Permission System

### Lesson 3: Create New Activities and Navigate Apps with Intents (8-10 hrs)
Give your app structure and create more complex Activities. You’ll learn about Android’s Intent framework, and how to use Intents to navigate between Activities, both within your app and as a way to add 3rd party functionality.

* App navigation with Explicit Intents
* Implicit Intents to incorporate 3rd-party apps
* Share Intent and the Android sharing framework
* Broadcast Intents and Broadcast Receivers

### Optional Project: Popular Movies, Stage 1 (5-10 hours)
Build an app to help users discover popular and recent movies. You will build a clean UI, sync to a server, and present information to the user.

### Lessons 4: Use Content Providers and Loaders to Persist and Recover Data (15-20 hrs)
Learn how the Android framework manages the activity lifecycle, and how it differs from what you might expect, and dive head-first into the world of persistent storage. Learn how to create databases, use Android’s Content Providers to provide an abstraction layer between your data and your UI implementation, and use Loaders to efficiently load stored data.

* Activity lifecycle and background activity termination
* SQLite databases and JUnit tests
* Creating and using a Content Provider as an abstraction layer
* Using Loaders to asynchronously load data
* Creating Adapters to bind UI components to Content Providers

### Lesson 5: Implement Rich and Responsive Layouts (8-10 hrs)
Create rich, responsive user interfaces that work across a variety of different hardware types and screen sizes. You’ll learn more details on using the Android Layout managers, Fragments, UI widgets, and Android design principles to add visual polish to your user interfaces, and how to create your own controls from scratch.

* Fundamental Android design principles
* Supporting localization and variable screen sizes
* Optimizing tablet UIs using Fragments
* Accessibility Features
* Custom views

### Lesson 6: Use Services and Notifications to Run in the Background (5-8 hrs)
Deliver a great user experience, even when your app isn’t visible. Learn how the Android framework manages background apps; and discover how to use Services and Notifications to make your app to be active when it’s not in the foreground. You’ll learn techniques for efficient data transfers using SyncAdapters and Google Cloud Messaging, so your app can stay up-to-date without draining the battery.

* Background services and alarms to schedule background tasks
* Efficient background data transfers with SyncAdapters
* Rich notifications to interact with users

### Optional Project: Popular Movies, Stage 2 (4-6 hours)
Add to the app you built in Stage 1 by building on the detail view for each movie, allowing users to 'favorite' movies, and adding a tablet layout.

### Final Project (10-20 hours)
Build your own Android app incorporating the skills you've learned in this course.
