推荐答案
如果您使用的不是演员,你没有指定任何这些标志。他们只改变系统是如何处理群众演员以的PendingIntent
:替换当前的匹配(由系统缓存的那些的PendingIntent
)或取消它,并创建一个新的。详情请参阅文档:的http://developer.android.com/reference/android/app/PendingIntent.html#FLAG_CANCEL_CURRENT
If you are not using extras, you don't have to specify any of those flags. They only change how the systems handles extras with a PendingIntent
: replace the ones in the current matching (cached by the system PendingIntent
) or cancel it and create a new one. Refer to the documentation for details: http://developer.android.com/reference/android/app/PendingIntent.html#FLAG_CANCEL_CURRENT
