推荐答案

A PendingIntent 是给外国申请一个标记（如 NotificationManager ， AlarmManager ，主屏幕 AppWidgetManager 或其他第三方应用程序），其中< STRONG>允许外国申请使用应用程序的权限执行predefined一张code

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.

如果你给了外国申请的意图，并且应用程序发送/广播意图你给了，他们将执行意图用自己的权限。但如果你给外国申请一个 PendingIntent 您使用自己的权限创建的，该应用程序将执行包含意图使用你的应用程序的许可。

If you give the foreign application an Intent, and that application sends/broadcasts the Intent you gave, they will execute the Intent with their own permissions. But if you instead give the foreign application a PendingIntent you created using your own permission, that application will execute the contained Intent using your application's permission.
