In the second screencast of this series, we’ll build upon the app we started in the first screencast and demonstrate how we can retrieve the payload of the tag within the Activity which was launched when the device detected a matching tag. Along the way we’ll explore some of the internals of how NFC tags are structured.
In the first screencast of this series we’ll cover the basics of NFC tags introducing NDEF and the Android tag dispatch system. We’ll look at how to add an intent-filter to the Manifest entry for a given Activity to enable that Activity to be launched when a matching tag is detected by the device.
What are some strategies for dealing with Kotlin and Android Lifecycles? In this screencast, cast you'll learn how Android Lifecycles appear to inhibit some core behaviors of Kotlin.
In this video you will learn how to tell a RecyclerView Adapter that the underlying data has changed. You will also see the typical quick way of telling it to update, as well as a much more efficient implementation.
In this video you will learn how to configure a RecyclerView and its Adapter to display mutliple types of views in the list. You will determine which type of view needs to be displayed depending on the data, create the appropriate view holder, and bind the model data to it.
Integration tests provide a way to verify the features in your application continue to work as you expect while adding new features and refactoring existing ones.

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.
