It all started in 2021 when I stumbled upon rawdrawandroid. My goal was simple: to create a game with the minimal APK size, yet still be understandable and interesting. 🎯
The idea of making a Flappy Bird clone seemed logical, given that this game had already been ported to many languages. 🐤
In 2021, I also studied Raylib, but my first attempt to make a game in C++ using ImGui failed. 💔
The problems were everywhere: the APK size was around 1 MB, the game crashed, and the APK only contained the armeabi-v7a library (Google's 2022 requirements state that the arm64-v8a library must be included!). 🤯
In September 2024, seeing Flappy Bird in C# in the Raylib Discord channel, I decided to try implementing this game in C for Android with an APK size of less than 100 KB. 🚀
The idea seemed crazy, but the competitive interest took over. 💪
I started by compiling a "Hello World" in C and packaging the library into an APK. 📦
Sounds were compressed to MP3 format, and OpenSLES was used for playback. 🎵
For PNG file decoding, I chose upng. 🖼️
All of this was combined using OpenGL ES 2, shaders, and Android Native Activity. 🎮
- Create .env from .env.example
- Run build.bat
For Linux and macOS users, you can build the project using the provided Makefile:
- Install the Android command-line tools.
- Set up your environment variables in a
.envfile in the project root directory (see.env.examplefor an example). - Build the project:
cd FlappyBird make
For more detailed instructions, please refer to BUILDING.md.
The signed APK will be generated at:
FlappyBird/app/build/outputs/apk/FlappyBird-signed.apk
