推荐答案

A PendingIntent 是您提供给外部应用程序的令牌(例如 NotificationManager、AlarmManager、主屏幕 AppWidgetManager 或其他 3rd 方应用程序)，它允许外部应用程序使用您应用程序的权限来执行一段预定义的代码.

A PendingIntent is a token that you give to a foreign application (e.g. NotificationManager, AlarmManager, Home Screen AppWidgetManager, or other 3rd party applications), which allows the foreign application to use your application's permissions to execute a predefined piece of code.

如果你给外部应用一个 Intent，它会用它自己的权限执行你的 Intent.但是，如果您给外部应用程序一个 PendingIntent，该应用程序将使用您的应用程序的权限执行您的 Intent.

If you give the foreign application an Intent, it will execute your Intent with its own permissions. But if you give the foreign application a PendingIntent, that application will execute your Intent using your application's permission.
