1.8mb by cargo build --release great,
but 7.4mb by cargo apk build --release --lib

after unzip this apk and check lib folder i found 18.5mb .so
why so much and how i can reduce it?
skia? only this renderer for android?

checked egui, minimal app is ~3.5mb

ui is simplest:

export component General inherits Window {
    Text {
        text: "Hello, world!";
    }
}

7.4mb and 18mb is too much for hello world, especially without std-widgets!
~21mb after install app on android, not electron acrtually, but so fatty

p.s. #9570, i think it's similar, but different. cuz desktop bin here is little-compact, but android...
