OS for embedded/kiosk mode

[lloydhussell]

Hello.
I am currently using the Android 9 build supplied by HardKernel, and I am trying to build a kiosk mode app. It's very difficult to achieve what I want, but I have done it in a very hacky and broken way which could create an unstable OS.
I am wondering if you provide any other OS that can remove the OS UI completely, as all I want is my application running in the foreground on startup. I have achieved this, but I am disabling secure settings, which I am not fond of.

Thanks for any help.

What language/framework are based for your application?

Did you use kiosk mode that provided from ODROID Settings? It will remove the OS UI things.

"What language/framework are based for your application?" - I am using Kotlin to build a native android app.

"Did you use kiosk mode that provided from ODROID Settings? It will remove the OS UI things." - I could not create a DPC, but I did manage to get it into Kiosk mode as a device owner. This did remove the home and recents buttons from the navigation bar, but it did not remove the navigation bar entirely. There were still the power, screenshot, and back buttons. I have been looking into the Android Management API as well to control it, but after doing a lot of research, it seems that Kiosk mode there also does the same thing, I would not be able to remove the bottom navigation bar completely. The only way I have truly achieved it is by executing the command ```adb shell settings put secure user_setup_complete 0```

hmm.. I can't see the navigation bar on the Kiosk mode.
Can you share your using resolution? I tested it on the 1920x1080.

And Please share your display screenshot.

Is the navigation bar completely disabled, though? I am able to swipe up from the bottom and still see the navigation bar, but I am restricted from going to home or recents.

Do you have a guide on how to enable kiosk mode properly like this? I have been doing so much research and keep coming to dead ends. Unfortunately I can't post a screenshot right now, sorry. But my resolution is 800x480 right now, but that will change soon.

I see now you mentioned it's actually with the ODROID itself, it allows kiosk mode. Would you be able to link me to the wiki page, please?

[lloydhussell]

Okay, I found how to turn it on, but then how do I turn it back off once it's on that mode? Because I am then locked into the application.

Sorry for late reply.

You can make it by two ways.

First, try it turn off with the ODROID Settings apk like it be turn on.

Second, If you can communicate with adb, please type it.

Code: Select all

$ adb shell
$ vi /odm/default.prop

then, Please change kiosk_mode value to false

Code: Select all

...
kiosk_mode=false
...

After reboot, kiosk mode will be disabled.
