Android Question Kiosk 2017 and immersive mode.

[EvgenyB4A]

At Kiosk 2017 there is "back" button and navigation bar. It is advised to use immersive mode. But at this mode if you slice by finger the top or bottom part of the screen the bars are appeared again. How to immediately hide them again?

You cannot prevent it. However you can catch the back key and the user cannot exit your app.

I am unsure if it will be useful to you, but on our Android device, there's a setting where even the top bar cannot be pulled down by the user. For us it was perfect in addition to Kiosk Mode. With the service running, you'd have to know exacly where to look for in order to allow access...

Settings -> Display -> Display Navigation

If you HAVE to get out though, we plugged a keyboard and did a TAB to slowly get back to the settings and disable that setting...
I also made the service shut down on password input...

Hi

It seams that it is possible , from Google developer site :

https://developer.android.com/training/system-ui/immersive

When the system bars re-appear, you can receive a callback to make other appropriate updates to your UI. See Responding to UI Visibility Changes.

Can you explain us how to do with B4A ?

Thanks !

Depending on your requirements it might also be interesting to investigate Samsung Knox, which makes for a pretty damn good lockdown, if you need it. (I know it's been discussed a couple of times here in the forum, but I don't know if it's possible to use with B4A.)

The quote you posted is not related to the question in this thread. The question was how to prevent them from appearing, not how to update the layout when they appear.

It is always better to start a new thread for your question.
