Recently, I looking for an light weight Andriod app that can display the daily crypto news. Unfortunately, I did find the app match my need. So I decided to write my own App. My first Andriod App was written with Reactive Native framework, which was not a good experience with JS. However, I have familiared with Rust, and also developed a few Rust desktop with Slint-ui. So I found egui is a choice for my situation, or maybe the best choice...
