android - 谁能告诉我 "on O+ for instant apps"是什么意思？

Question

以下资料来自Android Developer's page .我想在下面的上下文中理解什么是“O+”。是奥利奥之类的吗？

updateAppInfo

void updateAppInfo (Context context)

Updates application info based on currently installed splits.

Note #1: This method must be called after split is installed on O+ for instant apps, so that application components can see new resources and code from new splits.

Note #2: This method will update application info reference in application thread object.

Note #3: This method should only be called on O+.

Example usage:

 // SplitInstallAPI callbacks
  public void onStateUpdate(SplitInstallSessionState splitInstallSessionState) {
    if (splitInstallSessionState.status() == SplitInstallSessionStatus.INSTALLED) {
      // Use SplitInstallHelper API on O+ to update application info after the splits are
      // installed.
      if (BuildCompat.isAtLeastO()) {
        // Updates app info with new split information making split artifacts available to the
        // app on subsequent requests.
        SplitInstallHelper.updateAppInfo(context);
      }
    }
  }

Answer 1

是的。在这种情况下，O 是 Oreo 的缩写。 Android 的每个主要版本(从 1.2 开始)都以甜点或其他甜食命名，版本号为 codenamed in alphabetical order从 C for Cupcake 开始.版本通常会缩短到它们的第一个字母以便快速引用，或者在版本名称尚未确定时(目前是 Android P 的情况)。

因此在您的示例中，函数 BuildCompat.isAtLeastO() 检查当前设备是否至少运行 Android Oreo(API 级别 26)。
