I have found that Android recent app dialog can be disabled by disabling package com.android.systemui. I want to run my (rooted) device in kiosk mode so it is essential that the recent apps dialog not be shown on long press.
Now, exactly what does com.android.systemui do? I don't need notifications and power indicators and stuff so it is OK if that kind of cosmetic stuff disappears. It is also OK if soft input home buttons disappear because I have replaced them with a software app (Button saviour).
Is it safe to disable com.android.systemui, or do I risk subtle system hangs in certain unclear situations? To put it shortly -is it just another app, or is it absolutely essential to the Android operating system? (I haven't experienced any problems this far!)
Is com.android.systemui available in all Android versions?
