In this screencast, we’ll cover a new background work library introduced at Google I/O 2018 - WorkManager. This release will have a huge impact on most Android apps. Background work has always been painful in Android. There are many different ways to schedule a background work and of course they are different
The Navigation Architecture Component was introduced at Google I/O 2018. This new library aims to simplify navigation from one screen to another. In this screencast, we’ll see how to apply the navigation component to an existing app and review the major pieces and parts.
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.
In the final screen cast of the series we’ll return to the Android chooser behavior which asks the user which application they wish to use to handle a newly discovered tag. We’ll then look at how we can add an Android Application Record to our NdefMessage which will effectively specify that our app will handle the tag and bypass the chooser. While it is very light on code, the concepts do require a little explanation to make the code changes understandable.
In this screen cast we’ll further build upon the app from the last cast where we got foreground dispatch working to handle tag discovery events within a resumed Activity. We’ll look at how we can construct an NdefRecord, and an NdefMessage and write this to a tag. We’ll also look at the difference in writing to an Ndef tag and an un-formatted NdefFormatable tag.
In the third screencast of the Android NFC series, we’ll continue to build on the app we’ve been working on in the series so far. Now we’ll begin preparations to write to a tag by creating a new Activity which will use foreground dispatch to get notifications of any tags which are detected while it is in resumed state.

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.
