这是个正常的现象.因为edge设置了不在Recent里面显示

首次打开edge应用时,打开的是com.microsoft.emmx/com.microsoft.edge.fre.OrientationAdaptiveFirstRunActivity这个

<activity
android:autoRemoveFromRecents="true"
android:configChanges="keyboard|keyboardHidden|mcc|mnc|orientation|screenLayout|screenSize|smallestScreenSize"
android:excludeFromRecents="true"
android:label="@string/fre_activity_label"
android:launchMode="singleInstance"
android:name="com.microsoft.edge.fre.OrientationAdaptiveFirstRunActivity"/>

OrientationAdaptiveFirstRunActivity设置了不在Recent里面显示.

按照AOSP的逻辑,当设置了autoRemoveFromRecents或者excludeFromRecents时,并且它不处于RecentTask里面的第0个位置,就是不处于顶部时,它会自动从recent里面删除掉

按照现在的步骤
先打开OrientationAdaptiveFirstRunActivity,它处于第0个位置,所以可以在Recent里面看到,但是打开B站后,它就不处于第0个位置了,所以这个时候在进入recent,就会被删掉
