And this is the Android app:
TBD
Together they make magic happen. 🪄🦄
- Fork the repo & make write your code
- Use "droidcon/${name}" format for the branch name so we can find it.
- When done, open a PR and come to the booth to get you badge.
The following sections are describing the badge in detail, but if you just want to get started, please feel free to follow our Getting Started guide.
The following lines are the thought experiment on how we imagine a visit to the GDG Berlin Android Droidcon 2023 Berlin booth will look like. Alice is an atenndee and Olivia is an organizer.
| Actor | Dialog |
|---|---|
| Alice | Hey, I saw that thing everyone is running around, that with their name on it? They said I can find it here, is that true? |
| Olivia | Yes, you came to the right place, this is ZeBadge, a digital badge that displays your name and can be programmed and changed! |
| Alice | Oh that is amazing, how does this work? How can I get one? |
| Olivia | You need to do what we all love to do: Write some code and create a PR on our open source repository, controlling the badge and the android app. You can get started with using one of our loaner badges, and read one of our getting started guides. Once you have done "something code" with it, you can get your own badge. |
| Alice | Oh, neat, that is this qr code to get started points to one of the printed out sheets? |
| Olivia | Indeed, take loaner number four and happy hacking! Feel free to reach out when we can do something for you. |
| Alice went over to the loaners, played for 20 minutes with the badge, and was able to follow the getting started guide and create a new page system, showing the weather on page 2. She pushed a PR. |
