+ Next-Gen Functions
5 lectures 31:35
This video gives an overview of the entire course.
Preview 03:45
The aim of the video is to understand lambda expression in Kotlin.
Preview 06:11

In this video, we will explore functions in Kotlin and learn more about higher order functions.

Higher Order Functions
04:57
In this video, we will learn how we can use a special declaration known as extension functions to extend a class with a new functionality without inheriting from any class or by using design patterns.
Extension Functions
04:42

The aim of the video is to understand how we overcome the shortcomings of higher order functions by inlining the parameters.

Inline Functions
12:00
+ Interfaces
3 lectures 12:18

This video introduces the concept of interface in Kotlin and also explains how we can implement an interface with an example.

Preview 04:50

Unlike Java, in Kotlin we can declare properties in interface. This video helps us to understand how to add properties to an interface and accessing them.

Properties in Interfaces
02:07
In Kotlin, a class can implement multiple interfaces. In this video, we will learn how this can be achieved. This video also helps us to understand how to resolve overriding conflicts that might arise while implementing them.
Resolving Overriding Conflicts
05:21
+ Salient Features in Kotlin
6 lectures 55:10
The aim of the video is to understand how we can implement operator overloading in Kotlin with an example and learn more about unary and arithmetic operators.
Operator Overload
09:39

The aim of the video to understand what is implementation by delegation in Kotlin and how we can override the interface members.

Delegation
06:32

In Kotlin, we can implement a certain kind of properties only once and put them in a library. This video explains the concept using property and lazy delegates.

Property Delegation
08:05
Just like in Java, null pointer exception is a pitfall in Kotlin. In this video, we will learn how to deal with it Kotlin and discuss safe call and Elvis operator in Kotlin.
Null Safety
11:06
Unlike Java, in Kotlin have sealed classes, which is an abstract class and allows to be extended by subclasses only within the sealed class. This video explores sealed class and explains the benefits of using it.
Sealed Classes
09:48

When a fixed set of constants are required in Kotlin, we can use enum. This video helps us to understand how to initialize enum classes in Kotlin and working with enum constants.

Enum Classes
10:00
+ Exploring Anko and Publishing the App to Google Play
6 lectures 44:29

In this video, we will learn about the library Anko and how it can help us build apps more easily.

What Is Anko?
06:09

In this video, we will learn how to create Intents in a less verbose way than normal.

Simple Intents, Finally!
08:27

In this video, we will learn a simple way to show dialogs and toasts using Anko.

Dialogs and Toasts
11:46

In this video, we will learn how to incorporate flexible logging into our app using Anko.

Logging
04:16

In this video, we will show how to use AsyncTask in Kotlin, and how to use bg() which is much simpler.

Background Threads
03:28

In this video, we will learn how to create a signed APK of our app and publish it to Google Play.

Preparing for Google Play
10:23
Requirements
  • A basic knowledge of Kotlin is recommended.
Description

Kotlin greatly reduces source code verbosity. With Google having announced its support for Kotlin as a first-class language for writing Android apps, now's the time to learn how to create apps from scratch with Kotlin

The Applied Kotlin for Android Application Development course is for developers who have some experience in the basics of Kotlin and are ready to take the plunge into the more advanced stage. This course covers Kotlin's superpowers, as it were. You should already know the syntax, but now we will go over the things that make Kotlin stand out—such as inline functions and null safety.You will learn about Anko, a Kotlin library which makes Android application development faster and easier. It makes your code clean and easy to read and smoothes out the rough edges in the Android SDK for Java. You will also publish the app you built during the course to get an overall end-to-end experience of Kotlin Android application development.

By the end of this course, you will have gained experience in creating and deploying Android applications using Kotlin.
