Editor's Notes
- #3: 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!
- #5: Here are some the prerequisites that will be helpful. Having basic computer literacy and basic math skills is recommended. You’ll also need a computer and access to the internet to take the online course. [Mention WiFi instructions if necessary.] After this short presentation, we’ll all be working independently on the course. Use headphones to play the videos, so it doesn’t disrupt others around you. It’s also helpful if you have an Android device so you can test your app. A USB cable will be needed for connecting your phone to the computer. If you don’t have an Android device, don’t worry, you can still use your computer to emulate an Android device.
- #6: 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.
- #7: 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.
- #8: 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]
- #9: 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!”).
- #10: 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.
- #11: 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.]
- #12: 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.
- #13: 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.
- #14: 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.
- #16: [You can give them about an 1.5 - 2 hours to work on this, with another break as needed.]
- #17: Alright everyone welcome back! How was it?
- #18: 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.
- #19: 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.
- #20: 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.
- #21: 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.
- #22: After you pass the quiz, you earn a badge like this one!
- #23: 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]
