Editor's Notes
- [Wait for audience to join]
- Aravind: Hey everyone! We are glad you all could make it here today to join us for our introductory session. We will be taking you through what DSC is and how you can have a fun time with us. So without further ado, let’s get started.
- Aravind: Developer Student Clubs help students bridge the gap between theory and practice. These university-based communities cater to students interested in Google developer technologies. Students grow their knowledge in a peer-to-peer learning environment while building solutions for local businesses. Developer Student Clubs is a community where everyone is welcome. Developer Student Clubs is a program supported by Google Developers.
- Assuming you are in the right place, here are some the prerequisites that will be helpful for this track. 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.
- Let’s talk about what you will learn as part of this New to Programming track of Android Study Jams. 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.
- Let’s look at the schedule for this session. [Please update this schedule accordingly before your event.] 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!!
- 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.
- The course is made up of units, and units are composed of pathways. In this track, 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.
- 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.

All these activities are meant to help you reach specific learning objectives by the end of this pathway.
- 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.
- After you pass the quiz, you earn a badge like this one!
- 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]
- 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, and ranked as the #4 most loved programming language among developers, according to the 2020 Stack Overflow Developer Survey. Pathway 1 of the course is focused on helping you understand the basics of Kotlin. [Read about Android’s Kotlin-first approach]
- 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.
- 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!”).
- 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.
- Start by working on the first pathway in Unit 1 of the Android Basics in Kotlin course.
- Open the course page with the link we provided you, and you will automatically be awarded this badge for attending Android Study Jams! Save it to your developer profile, and create a profile if you haven’t already.
- Then under the New to Programming track in the left hand box, click the green button to start the Android Basics course.
- [You can give them about an 1.5 - 2 hours to work on this, with another break as needed.]

- Alright everyone welcome back! How was it? Were you able to create a birthday card? Does anyone want to share what your app looks like?
- 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!
- Stay tuned for our next session -- you’ll be learning more about Android and Kotlin to build an interactive app! Thank you for coming and see you soon. [Insert details for Session 2 if it will start later in the day or on another day.]
- If you liked creating your first Android apps and want to continue learning more on your own, here are some resources.
- First, you can continue learning on your own with the Android Basics in Kotlin course. At the moment, Unit 1 is available (which you already completed), with more units being released as they become available. In the meantime, 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. Thank you so much for being a part of Android Study Jams! Good luck on the beginning of your Android developer journey!
