如何在完成时从最近的应用列表中删除活动？

Question

I'm launching an activity from a service and want it to appear in the recent apps list.

However, I want the activity to be removed from the recent apps list if I exit the application (eg press button on activity's UI which calls finish()).

Excluding the activity from the recent apps list with android:excludeFromRecents="true" does not give me the initial activity behaviour that I require, ie the activity appearing in the recent apps list.

Is this possible?

Answer 1

Use

android:excludeFromRecents="true"

for the activity in manifest file

android:excludeFromRecents

Whether or not the task initiated by this activity should be excluded from the list of recently used applications ("recent apps"). That is, when this activity is the root activity of a new task, this attribute determines whether the task should not appear in the list of recent apps. Set "true" if the task should be excluded from the list; set "false" if it should be included. The default value is "false".

Answer 2

对于api> 21你可以尝试finishAndRemoveTask()而不是finish()

Answer 3

Yes, generally when you want to have special properties for an Activity when starting it you supply special flags to the Intent. In this case FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS .

Updated:

If you need to hide the current already running activity, you might be able to use this flag in combination with FLAG_ACTIVITY_CLEAR_TOP which would send the new Intent to the existing Activity. You'll have to think and perhaps experiment with what happens as the user moves around your stack though and whether that will make your app re-appear in the recent apps.
