同じ(ように見える)機能はどうする?
わかりやすい機能はライブラリ化済み
- カメラ
- 写真ピッカー
建築ドメイン色が強かったりプロダクト固有の事情があると独自に実装さ

BaseActivityとは
画面の基本コンポーネントであるActivityを継承した神クラス。複数の画面で利用
する処理やボイラープレートを実装して各画面のActivityで継承して利用する古の
デザインパターンです。神クラスなのでそれぞれ関係が無いけど重要な機能が集
まって可読性が落ちるといった問題が起こりがち。昔はライフサイクルメソッドに
連動した処理を切り出すのが難しかったので止む終えない感じもしましたが
LifeCycleObserver等の登場によって過去の遺産となりました(多分)。
アンドパッドのBaseActivityも神として崇められた結果†Dagger†Componentの
injectや共通エラー監視・特定の種類の画面でしか使わない処理などが大事に保管
されています。本当は今すぐ消したい。

作業コストが低め
構造を大きく変える必要がない
→大掛かりなアーキテクチャ変更はリードタイムが長くなってしまう
サービス的に意味のあるまとまった単位で改善できる
→画面単位の改善だとミクロな視点になりがち
