👉 Glide v4 : Fast and efficient image loading for Android

@sjudd Hey, I believe you're one of the maintainers of Glide. Is it a planned feature? Does Glide's team want help from the community on this? Jetpack Compose is going to stable soon, I believe later this month or next month

👉 Picasso

Nobody works on Picasso. If you want something in the next N years definitely use Coil. Or Glide. Or whatever. They're all fine.

Image loading is a terrible, horrible business to be in. It's been really nice not being in that business for the last few years. I don't see a reason to resume. I certainly have no intent to support it anymore. Picasso accomplished its goal of moving the ecosystem out of the painful image loaders of 2011/2012 to the fluent and extensible ones we know today. But it's filled with technical debt and the legacy of poor design (at least, in hindsight) and is currently very, very stuck between a major refactor and redesign with no end in sight.

👉 Coil

To add support for Jetpack Compose, import the extension library:

アーキテクチャー、フレームワーク、ライブラリの選定はそのプロダクトの安定感に直結します。

機能確認を中心に検証しながら、将来の本筋を外してはなりません。

scan() すると、画面のツリー構造がテキストで取得できるようでです。

// Render the view hierarchy for all windows.
val prettyHierarchy = Radiography.scan()


// Extension function on View, renders starting from that view.
val prettyHierarchy = someView.scan()

Jetpack Compose でやってみる

この画面でやってみます。

Composable にコードを追加しておきます。


@Composable
fun HomeScreen(
  viewModel: HomeViewModel = hiltViewModel()
) {

  // ...

  val view: View = LocalView.current

  SideEffect {
    println(Radiography.scan())
    println(view.scan())
  }

}

どう使います?、これ。

scan() 時のオプションもいろいろあるようなので試してみますか。
