自 2025 年 3 月 27 日起,我們建議您使用 android-latest-release
而非 aosp-main
建構及貢獻 AOSP。詳情請參閱「Android 開放原始碼計畫變更」。
將程式碼變更納入功能啟動旗標
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
以下範例說明如何在旗標中包裝程式碼變更。
if (Flags.myNewFlag()) {
// execute untested code
} else {
// continue as though untested code isn't present
}
在前述範例中,aconfig 工具已產生名為 mynewFlag
的方法,用於檢查標記的值。如果為 true
,系統會執行新程式碼。如果為 false
,流程會照常進行。
