Android:下载管理器和 COMPONENT_ENABLED_STATE_DISABLED_UNTIL_USED

Question

我正在尝试正确解决禁用的下载管理器问题。我能找到的最佳信息是 How to Enable Android Download Manager .

PackageManager.COMPONENT_ENABLED_STATE_DISABLED 和 PackageManager.COMPONENT_ENABLED_STATE_DISABLED_USER 状态对我来说是完全可以理解的。

但经过一个小时的谷歌搜索，我仍然对 PackageManager.COMPONENT_ENABLED_STATE_DISABLED_UNTIL_USED 感到困惑。

Documentation阅读:

Flag for setApplicationEnabledSetting(String, int, int) only: This application should be considered, until the point where the user actually wants to use it. This means that it will not normally show up to the user (such as in the launcher), but various parts of the user interface can use GET_DISABLED_UNTIL_USED_COMPONENTS to still see it and allow the user to select it (as for example an IME, device admin, etc). Such code, once the user has selected the app, should at that point also make it enabled. This option currently can not be used with setComponentEnabledSetting(ComponentName, int, int).

这是否意味着我应该将此状态视为已启用？

用户如何选择 DownloadManager？它如何显示？
