mMainStack.mHistoryのActivityRecord情報からListを生成します。final boolean switchUser() private final void startActivityLocked() private final ActivityRecord resetTaskIfNeededLocked() private final ActivityRecord moveActivityToFrontLocked() final void moveTaskToFrontLocked() final boolean moveTaskToBackLocked()Activityをstartしたり、起動済みのActivityをFrontに移行する際に呼ばれていました。
removeActivityFromHistoryLockedこのモジュールはActivityがDestroyされるときにコールされます。
final boolean destroyActivityLockedつまり、アプリ内のすべてのActivityがDestroyされるとmMainStack.mHistory内から抹殺され、 (onStop状態でも)Activityが一つでも残っていればmMainStack.mHistoryに存在することとなります。
