android and fullscreen


i noticed that android chrome displays the fullscreen button...

this makes not much sense on mobiles and just needs "button space"

does anybody know if it is possible to
auto-enter and always stay in fullscren on androids?

best, index

ps. it seems that if you switch to landscape fullscreen gets activated automatically

the fullscreen button makes sense! ;-)

The only problem is that Android Chrome has changed its default behavior and doesn't switch to a 'real' fullscreen anymore.
E.g. compare to Android Firefox, that hasn't that problem.

But the next krpano release also addresses that problem - for Chrome versions older than 74 it will use a hack (an old prefixed API) for fullscreen that still provides a 'full'-fullscreen mode, and for Chrome versions 74 and up it uses a new introduced fullscreen API that allows using the 'full'-fullscreen mode again.


That's based on another special Android Chrome fullscreen API and can be enabled or disabling using that setting:

oi, that is confusing .-)

my problem is i have too many buttons in my controlbar, already
and with an additional fs-button they overflow on android phones *rolleyes*

i was hoping it is possible to get something iphone/ios like on android
the app always on auto-fullscreen without need of a fs button.

something like display.autofullscreen but also for portrait

something like display.autofullscreen but also for portrait

Entering fullscreen mode always requires a user-gesture or with the special Chrome API a 'rotation to landscape'.

You could also use the global onmousedown or onclick events to switch to fullscreen mode but that can be also a bit annoying when it happens constantly...

thanks for the infos klaus,

i had already read that it needs an user interaction,
but i didnt know about the 'rotation to landscape' api

conclusion is probably,
that there is no way around the fs button on chrome android
