android - Removing activity from recent apps keeping older one

Question

I have this challenge with my Android APP:

I have and "dialog" - I mean an activity created as a dialog. Now, user presses the home button and leaves the app ~ later holds the home button and displays the Recent apps list. He will see the dialog as the last activity of my app. However, I don't want to display this activity on the "stack".

I tried the exceludeFromRecentApps (or similar name) and this one enabled removes whole app from the list. But I want to have dialog's parent activity displayed in the list. I tried something with overriding the onResume, onPause and onStop methods, but no effect for me, since instance-level variables may be discarded (?). I believe thats trivial problem, but I wasn't able to google working solution.

Lot of thanks!

Answer 1

android:noHistory="true"
android:taskAffinity=""
android:excludeFromRecents="true"

对于您的情况，首先您需要通过“taskAffinity”标签分隔您的对话活动。然后，您需要 AndroidManifest.xml 中的“excludeFromRecents”标签从最近列表中删除。

Answer 2

就像Hoan Nguyen说的那样，您需要使用该finish()方法，但要知道该finish()方法并不能保证 Activity 将完成。
