In this video you will learn about ConstraintLayout. It will cover how to use the graphical editor, how to add constraints to your views and tweak their attributes to position them on screen, and it has an example of converting an existing layout to use ConstraintLayout.
CoordinatorLayout is a tool that allows you to coordinate the movement of one view with another. In this screencast, you will see a few examples of how CoordinatorLayout can be used and how to customize its behavior. We consider this tool to be the best kept secret in Android development. We say that because it's a tool that is powerful but under used. Watch as we use CoordinatorLayout to create some interesting UI patterns where views can respond to the movement of other views.
In this screencast, you'll learn how to be more productive with these useful navigation and editing keyboard shortcuts in Android Studio.
Dagger is a dependency injection framework. In this screencast you will learn how to set up Dagger in a Kotlin Android app and some best practices.
App shortcuts give you the ability to provide convenient shortcuts to specific actions in your application. They provide an entry point to different parts of your application. In this video learn how to implement app shortcuts and give your users quick access to the functionality they want.
Android view click listeners are often implemented inline using anonymous inner classes. Lambda syntax offers a more streamlined syntax.

Tight coupling between view controllers in your application can lead to difficult maintenance as you add and remove features. This video will explore how using Protocols can make our Dependency Injection more loosely coupled. This improves the flexibility of the code and makes our application easier to change.
UIStackViews are a relatively new addition to UIKit, appearing with iOS 9. They are quite useful because they eliminate the need for many Auto Layout constraints in common screen designs, making them easier to modify and maintain.
As View Controllers become more complex, the need to manage the state of the view becomes more important. In this video we will discuss how to use a state machine to manage our views state.
Sometimes your app design calls for a control design that isn't provided in UIKit. In this video, we draw one from scratch!
When you have a complex view controller view, sometimes it is helpful to break up the view into manageable chunks. In this video we will show how you can use container views to simplify the construction of certain layouts. After this video you will know when and how to use these container views in your applications.
While Android SDK provides the APIs for using SQLite databases, they force developers to write a lot of boilerplate code. Room solves this problem by creating the glue code that saves objects to SQLite and reads them into memory. In addition, it performs some compile-time checks to ensure correctness of SQL queries.
