New Course: Your Second Kotlin Android App

It’s day 3 of the Android Avalanche: an event where we’ll be releasing new Android and Kotlin books, courses, and screencasts every day!

Today, we are releasing a brand new course: Your Second Kotlin Android App. After you’ve completed Your First Kotlin Android App and Programming in Kotlin, continue your Android development journey by creating another app. Not just any app, but a TODO list app.

You’ll build this app from the ground up and in this 39-video course by Brian Moakley. Take a look at what’s inside:

Part 1: Getting Started

In part one, learn about a recycler view, what they do, and how to incorporate it into your app.

1. Introduction: A journey of a thousand android apps starts with the creation of your second one. Learn about the course objectives and what you will build.
2. Creating a Project: This video will get you started on making your second app as well as explain some of the project creation features.
3. Adding a Recycler View: When creating a lists, a good tool to use is RecyclerView. This video will get you started.
4. Setting up a Recycler Adapter: Having a RecyclerView isn’t enough. You also need an adapter. Learn about adapters in this video.
5. Challenge: Filling in the Blanks: With your adapter created, you just need to hook it up to the activity.
6. Creating a View Holder: The adapter managers the data. The view holder handles the view. This video gives you an overview of the process.
7. Challeng: Binding Data: With your RecyclerView in place, the only thing left to do is present the data which just happens to be your challenge.
8. Conclusion: With your list setup, you’re just getting started. This video points you towards your next steps.

Part 2: Saving Data

In the second part, save your todo lists by way of shared preferences and how to read them back again.

1. Introduction: Creating lists isn’t enough. You’ll ultimately need to save that data which is what this part covers.
2. Adding a Dialog: To add items, you’ll need to create a dialog and thankfully, Android has a ton of them.
3. Shared Preferences: Shared Preferences is a way that we save data. This video covers the basics of using it.
4. Challenge: Instancing Your ListManager: You’ve created a ListManager class. You’re challenge is to create an instance of it.
5. Hooking Up the Activity: Now that we have our shared preferences in place, it’s now time to hook them up with the main activity.
6. Conclusion: With your data being saved, all you need to do is pass data between activities which is the topic of the next part.

Part 3: Communicating Between Activities

In part 3, create multiple activities and learn how to pass data between them.

1. Introduction: Apps comes with a lot of different activities and in this part, you’ll learn how to pass data between them.
2. Challenge: Creating Another Activity: Before you can pass data between activities, you’ll need to add a new activity.
3. Intents: Intents are a fundamental part of working with Android.
4. Parcels: Parcels are another way to pass data which is useful for packaging objects.
5. Bringing Everything Together: With your preferences in place, all you need to do is integrate it with the rest of the app.
6. Conclusion: This video reviews the topic covered in this part.

Part 4: Working with Fragments

In part 4, refactor your app into fragments and get it to work on a multiple screen sizes.

1. Introduction: While your todo list is going on the phone, it’s looking terrible on tablet. You’ll fix this by way of fragments.
2. Creating a Fragment: This video will walk you through the process of creating a new fragment.
3. Integrating Fragments in Activities: This video will show you the process of replacing activity code with a fragment instead.
4. Challenge: Setting Up a New Device: A great way to test your new layout is to create a new virtual device which is your challenge.
5. Showing the Fragment: Now that you have the fragments created, all you need to do is use them.
6. Challenge: Creating a New Fragment: Your challenge is to create a new fragment. Are you ready for it?
7. Layouts for Larger Screens: Unfortunately, one layout doesn’t work for all devices. Thankfully, you can create others.
8. Challenge: Setting up the RecyclerView: Now that you are exerienced with the RecyclerView, try creating one on your own.
9. Completing the Detail List View: There’s a few items left to finish before your done.
10. Adding List Items: You need a way to add todo items to your list and you’ll do this with your old friend, the floating action button.
11. Return Data from Activities: Somtimes activities return data and in this video, you’ll learn how to do that.
12. Conclusion: At last, you have a working app. What’s next? This video has you covered.

Part 5: Android Material Design

In the final part of the course, learn about Android Material Design and how to use it to improve your app.

1. Introduction: Your app may be functional, but it doesn’t look good. This video lets you know why it’s important.
2. Material Design: Thankfully, Android has materials to help you design your app.
3. Primary and Secondary Colors: When working with apps, it’s useful to think in primary and secondary colors.
