I have developed this Android application back in 2014. I had no Git experience yet, so unfortunately no commit history is available. However, you can look at the code I wrote as an undergraduate.
It was the time I saw many soundboard apps rise and decided to create my own soundboard application with the custom sounds which I found hilarious at the time.
First time I got my hands on the MediaPlayer and abused the Activity Lifecycle: https://github.com/vlmaier/tap-for-sound/blob/main/app/src/main/java/com/vladas/tapforsound/MainActivity.java#L83
