if we want to see notification bar
we put in sys.txt
[android]
fullscreen=0

[rawdisplay]
driver=engine
;screen_xy="auto"

if we don't want notification bar
we put
[android]
fullscreen=1

rawdisplay]
driver=engine
;screen_xy="auto"

in any case ,we disable screen_xy="auto"
like this ;screen_xy="auto"

and we disable
All the other resolution

only from the fullscreen 1 or 0
