Notes de l'éditeur
- 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 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!!
- Let’s start off by recapping what we did last time. Can you remember what you learned in Session 1? [Ask the group and create a list of everything that people recall. If people forget any of the following, be sure to remind them: How to write and run a program in Kotlin How to set up Android Studio on their computer How to start a project from a template in Android Studio How to run an Android app on the emulator (and a physical device, if applicable) Add text and images to a layout Modify attributes on a TextView or ImageView]
- That’s all we’ll cover for today -- let’s get started!
- In this session, you’ll complete Unit 1 of the Android Basics in Kotlin course by finishing Pathway 4: Add a button to an app. In this pathway, you’ll be building an interactive app called the Dice Roller app. It rolls a dice when the button is pressed and updates the screen with the result.
- 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.
- Subclasses can have their own properties - much like objects can have their own values Abstract classes - not a concrete idea

- 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.
- 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)]
- 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!
