Editor's Notes
- #8 Let’s look at the schedule for this session. [Please update this schedule accordingly before your event. If attendees install Android Studio beforehand, then you can shorten the time allowed for Pathway 2.] First, we have a short presentation, which we’re doing right now. We’re covering some logistics and a high-level introduction to the concepts, to help you with the hands-on portion of the session later. Once I’m done talking, you’ll be able to dive into the course. You’ll be working independently on 3 pathways in the first unit of the course. This is just a suggested schedule. You can work through the pathways at your own pace and let me or any of the other facilitators know if you have questions. We’ll also have a short break in between. At the end of the session, I’ll bring everyone together and we can recap what we learned today and celebrate your progress!!
- #10 Hi everyone! My name is <Insert Name> and welcome to Android Study Jams! This is session 1 of Android Basics. This is for people with little to no programming experience, we start at the beginning and you’ll learn how to build simple Android apps in Kotlin!
- #16 The decision to have attendees install Android Studio on their computers beforehand is up to your preference. Option 1: You can have attendees install Android Studio as part of the hands-on codelabs. There are instructions within the two tracks for students to install Android Studio. This will take up more time during your session, but will allow them to ask questions if they need help with the install and set up process. Option 2: You could ask attendees to install Android Studio on their own before attending a session. Just be sure to let them know that this is expected of them prior to the session. These instructions may be useful.
- #17 Before we dive into the content, I want to get to know you better and what brought you here. Please take out a piece of paper. Take a moment to think about your answers to these questions and write them down. [Give 2-3 minutes to work and when most people have put down their pencils, proceed.]
- #18 Before we dive into the content, I want to get to know you better and what brought you here. Please take out a piece of paper. Take a moment to think about your answers to these questions and write them down. [Give 2-3 minutes to work and when most people have put down their pencils, proceed.]
- #19 Let’s talk about what you will learn as part of Android Basics. First and foremost, the goal is for you to build your first Android apps. To do this, you’ll install Android Studio on your computer, which is an application to build Android apps. Along the way, you will be exposed to programming concepts and the Kotlin language. At the end, we’ll also talk about resources on how you can continue learning and building apps beyond this event.
- #20 After you pass the quiz, you earn a badge like this one!
- #21 You’ll be working through the Android Basics in Kotlin course. This is a free online training course developed by Google for people like yourself to learn how to build basic Android apps.
- #22 The course is made up of units, and units are composed of pathways. First we’ll be focused on the first unit, which is shown here. It has made up of 4 pathways. In Session 1, you’ll work on the first 3 pathways: 1) Introduction to Kotlin, 2) Create your first app, and 3) Build a basic layout. In Session 2, you’ll work on the 4th pathway, which is a little longer. [Mention future sessions if your group will be meeting for longer.]
- #23 You may be wondering, what is a pathway? It’s an ordered sequence of activities to learn a specific skill. An activity can be a video, hands-on coding tutorial (known as a codelab), an article, or quiz. You can see at least 4 activities in this first pathway. All these activities are meant to help you reach specific learning objectives by the end of this pathway.
- #24 There’s a quiz at the end of each pathway to check your understanding of what you just learned. Here’s what a sample quiz looks like. There are no limits to the number of retries for a quiz. But if you get a question wrong, try to understand what the concept is (even if you need to look back at the source material), before answering again.
- #25 The badges you earn can be saved to your developer profile. When you are taking the course, be sure to sign in (in the top right corner) and create a developer profile if you haven’t already. It’s very quick to create. As you earn more badges, you can see them on your developer profile and favorite them, as shown here. [Read more on the Google developer profile]
- #27 Now that you’re familiar with the learning platform and how the course looks, let’s dive into some important concepts that you’ll be learning about.
- #28 In this course, you’ll be learning how to code in Kotlin. Kotlin is a programming language that you’ll use to build Android apps. Kotlin is a modern and popular programming language, known for helping developers be more productive. Kotlin allows you to be more concise when writing your code, and you can write safer code that’s less prone to errors. As a result of many great language features, Kotlin has quickly gained momentum in industry. It is reportedly one of the fastest growing programming languages, according to GitHub. Pathway 1 of the course is focused on helping you understand the basics of Kotlin. [Read about Android’s Kotlin-first approach]
- #29 To make it easier for you to learn, you’ll be writing your code in the Kotlin Playground which you can access via the web browser. The site looks something like this. You can write your code in this window and hit the green arrow to run it. The result of your code (known as the output) will show up at the bottom of the window (where it says “Hello, world!”).
- #31 Pathway 2 is where you create your first app! You will need to download and install Android Studio on your computer. This is the official tool that professional developers use for Android development. This is where you’ll be writing your Kotlin code and building your apps.
- #32 In Android Studio, you can also use the Android Emulator, which can emulate various Android devices on your computer. The emulator allows you to run your app and it provides almost all capabilities that a real Android device would have. If you do have a physical device and want to use it, there are also instructions in Pathway 2 to get you setup. [Students can either use the emulator or a physical device to test their app, it’s up to personal preference.]
- #33 Lastly, in Pathway 3, you’ll learn the basic concepts of customizing the user interface of a simple app. The user interface (also known as UI) of your app includes what the app looks like and how the user interacts with it.
- #34 The layout of an app is the design or arrangement of what the user sees on the screen. In Android, a layout is made up of Views.
- #35 Here are some examples of types of Views that are provided by Android: TextView for displaying text, ImageView for displaying images, and Button to perform some action when tapped.
- #40 To build this app, you’ll need to understand what an activity in Android is. An Activity is the part of your app that presents a window that can display the app's content on the screen. In the Dice Roller app you’ll be building, there is only one Activity called the MainActivity. When you open up the app, the MainActivity launches, the layout is drawn on the screen, and the user can start interacting with the app. You will be modifying the MainActivity by adding Kotlin code for what should happen when the user taps the button in the app. Introduction to Activities Activity class
- #41 As you write Kotin code for your app, you’ll need to understand what classes and objects are. You can think of a class like a blueprint. It contains instructions for how to create something. From the Dice blueprint, you can create actual Dice. More specifically, the Dice class contains details like what properties a Dice has (e.g. number of sides) and how it behaves (e.g. it can be rolled). The great advantage of having the Dice class is now you can create as many Dice object instances as you want, as shown in the diagram. It saves time from having to write all the same code over and over again. This makes your code more organized and easier to maintain. [Optional: You could also use this analogy. A blueprint of a house contains the instructions of how to create the house. But the blueprint is not the house itself. The actual house is the object instance, and you can create multiple house object instances from the same blueprint.]
- #42 Okay that’s it! In a moment, I’ll let you get started on the course. Work at your own pace. If you get stuck, you can ask me or the other facilitators who will be available. [Introduce facilitators if applicable.] We’re here to answer whatever questions you have, for example, if you need help installing Android Studio or getting your app to run on your Android device. Also feel free to ask each other for help and work together to find solutions.
- #44 [Optional slide. If you choose to use this, right click on the slide and unselect “Skip slide”] [Full screen the video when you play it.] As you continue to learn more about programming in this pathway and beyond, you will run into challenges that you may feel overwhelmed or intimidated by. That is a normal feeling and it’s known as Imposter Syndrome, which many folks in the industry deal with. We want you to be aware of it because there are small actions you can take to overcome it, as the video talks about. [Additional blog post on why learning to code is so hard]
- #46 Great job everyone on your progress! You can post photos or highlights from today’s session on social media using #AndroidStudyJams. [Include your own developer community and chapter hashtags (i.e. #developerstudentclubs #dsccmu)] We encourage you to share a screenshot of your birthday card app!
- #48 Welcome back to Android Study Jams! My name is <Insert Name> and today we’ll be completing session 2 of Android Basics. As a reminder, these sessions are designed for people with no prior programming experience to learn how to build basic Android apps in Kotlin.
- #49 Let’s dive into some of the high-level concepts you’ll be learning.
- #50 That’s all we’ll cover for today -- let’s get started!
- #51 [Optional slide.

- #52 [You can give them about an 1.5 - 2 hours to work on this, with another break as needed.]
- #53 Hope you all enjoyed the game and learning to create the Dice Roller app! On social media, remember to post photos or highlights from today using #AndroidStudyJams. [Include your own developer community and chapter hashtags (i.e. #developerstudentclubs #dsccmu)]
- #55 After you pass the quiz, you earn a badge like this one!
- #56 [You can give them about an 1.5 - 2 hours to work on this, with another break as needed.]
- #57 Thank you Tanish! So you can keep coming to Study Jams as we cover more topics to make you a full fledged Android developer. You all can continue learning on your own with the Android Basics in Kotlin course. You can modify the apps we built together and learn by adding more features to them. You can use Google search or look at existing code samples and videos online for how to add additional features to your app. To stay connected, check out these additional resources, which professional developers use to stay up to date on Android. As you get into more advanced features, you will likely need to learn more programming concepts. You can check out the Learn Kotlin By Example resource for that.
- #58 These are some more resources that can help you throughout your journey of becoming an Android Developer. Here are some of the Online Curriculum courses , some kotlin language resources and some Android resources that you can check out and don’t worry all the respective facilitators will share all these resources with you after the session. Moreover we want to let you know that we are planning to conduct another amazing session related to Android Study Jams on 11th of December. More details on that we will share soon so stay tuned. Good luck on the beginning of your Android developer journey!
