By persisting your data, you can provide users with a more seamless experience with your app—even when they go offline. If you're an Android app developer, you have many data persistence options to choose from. In this course, learn about various options for storing your app's data in a database. To begin, Annyce Davis reviews using the de facto data persistence solution available on Android: SQLite. She takes you through basic SQLite concepts—such as how to create a database wrapper and insert data into a table—as well as a few more advanced topics. Next, she covers working with Cupboard, an open-source project dedicated to simplifying your SQLite interactions. To wrap up, she dives into working with Realm, an object database solution designed with mobile devices in mind. Throughout the course, Annyce discusses establishing relationships between database tables, creating and running queries, as well as performing data migrations.

Topics include:
- Overview of SQLite
- Defining a database table's schema
- Exploring SQLite create table syntax
- Executing create table statements

Android App Development: Design a User Interface
Create a user interface (UI) for a mobile app built with the Android SDK. David Gassner shows you how, in this course. David starts by exploring layout options, including views, components, measurement units, and loading layouts at runtime. Then he moves on to using ViewGroup components, showing you how to align interface elements with the new ConstraintLayout, and how to use the LinearLayout and RelativeLayout components. Next, he covers text, demonstrating how to display strings and collect information from the user with input fields. Finally, he shows how to create themes, use styles, and display images.

Topics include:
- Using View components
- Exploring the design repository
- Using the new ConstraintLayout component
- Adding views to a ViewGroup with Java
- Manage string values as resources
- Working with TextView, EditText, and TextInputLayout
- Displaying toast and Snackbar messages

Android App Development: Building Battery-Conscious Apps
Battery life remains the bane of every Android user. Poorly written apps can contribute to battery drain and impact the user experience across the entire device. If your app is outed as a battery hog, that's a fast path to bad reviews—and a high uninstall rate. This course teaches developers how to build battery-friendly apps that are efficient without compromising on functionality or performance. Instructor Ravi Subramanian introduces common programming patterns that result in higher-than-normal battery usage and recommends new ways to write code to use resources more efficiently. He also shows how to use the JobScheduler API to perform deferred work and how to discover and diagnose battery consumption "hot spots" in apps with Battery Historian. Plus, learn how battery-saving features Doze mode and App Standby will affect the performance of your app.

Topics include:
- Principles of building battery-conscious apps
- Causes of excessive battery drain
- Correct usage of Alarm Manager, services, broadcast receivers, and threads
- Working with the Android JobScheduler API
- Monitoring and acting on battery state changes
- Handling Android Marshmallow Doze mode
- Diagnosing battery issues with the Battery Historian tool

Android App Development: Modern Android UI Design Elements
Bring your apps into the modern era. Android UI design has evolved, and an Android developer needs to know about the most popular UI elements used today and when to use them. This course teaches developers how to incorporate side navigation drawers, create view holders, and implement custom layouts and views, and design a RecyclerView for mixed view types—such as a category header view and photo item view. Instructor Albert Lo grounds the lessons in a real-world project: a photography app that pulls photos from multiple sources, including Google Photos, and uses the new UI elements to display them in an interactive grid. Following these techniques will lead to more sophisticated and engaging user experiences for your Android apps.

Topics include:
- Creating a custom layout with XML
- Setting up OnClick handlers
- Making API calls
- Creating custom views
