I need to hide the navigation bar on a tablet with 4.0 completely. No user interaction should change this behavior. Right now I'm running the default Fullscreen View from Android Studio, but user interaction brings up the navigation bar.
Is there a way to do that without root?
Unless phone is rooted - you cannot override the standard behavior or Android OS.
In fullscreen mode i will be hidden, but can be still brought down when required.
You could set the app like a Launcher, hide the navigation bar, and root the phone, in order to set always run that.
The other option is root the phone, and make your own android version without the navigation bar.

Is there any way in react-native to know if an android device has soft navigations keys (the bottom buttons). For example, in Xaiomi Mi 8 the navigations keys are configurable and can be removed.
In my use case, My view changes if the device navigations keys are shown or not.
You can try this module
react-native-detect-navbar-android
Refer Here
This module tells if android device has soft navigation bar or not.
Hope this works for you !
I have found non rooted apps which are capable of hide home button from bottom system bar of tabs (not all the devices but many of samsung tabs) & disabling (not hiding) right side wifi, settings entering panel in system bar (worked in all the testing devices). Good example is remote lock screen of Lookout premium app with BIND_DEVICE_ADMIN permission. This lock screen appears on top of the native android lock screen it has these features work in many devices.
Is there a way to create an activity with disabling System bar like that? Is it related to the flag that adding to the layout params of the activity? Otherwise how this is implemented?
Thanks.
I am developing an android lock screen and need to disable the navigation bar. Using a launcher you can disable the home button and you can override the back button, but you cannot override the recents button. Is it possible to disable or clear the recents soft key temporarily?
Follow up question - has anyone been able to programmatically disable and enable the nav bar via root on jelly bean?
What about using lights out mode and overriding onSystemUiVisibilityChange while capturing the touch?
I have decompiled toddler lock - which implements this functionality, but it uses some hackery and the main activity is corrupted.
There is no way to this on a stock device. You'll have to customize the Android OS. Any 'hackery' you are seeing is likely to break with the next update. You can't really replace the system lock screen either.
I'm trying to make my app to Fullscreen (with no any bar) how I can coding to set it. (Android version 4.0.3)
Thx very Much
You can't hide that bar. On Honeycomb(3.0) there was a bug that would allow it to be hidden(on a rooted device), but it was fixed in ICS(4.0). (Note: see this answer for more techniques that worked on 3.0)As of now there is no way to do it on 4.0. Unfortunately, because devices no longer have physical buttons the navigation buttons (home and back) have to be put onto the screen. Because that bar contains the navigation buttons if you were to hide it, it would be possible to "lock" the user out of the device by not allowing them to leave your application(at least until they rebooted into safe mode).
So if you want to do that you'll have to make your own custom version of the OS to allow for it.
I want to make my application go fullscreen in any android device. Hide the Title bar and also the notification bar. The application is supposed to run on a 10 inch tablet on Android 4.0.3.
I am using the following code but only the title bar disappears. I want to hide the notification bar also. Can anyone please tell me what I am doing wrong in my code ?
getWindow().requestFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
try this
getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
Hope it helps.
Edit:
The SYSTEM_UI_FLAG_HIDE_NAVIGATION is a new flag that requests the
navigation bar hide completely. Be aware that this works only for the
navigation bar used by some handsets (it does not hide the system bar
on tablets). The navigation bar returns to view as soon as the system
receives user input. As such, this mode is useful primarily for video
playback or other cases in which the whole screen is needed but user
input is not required
.
The thing holding the navigation buttons back and home, time, network information etc is referred to as "navigation" bar.
You can not hide it within the given framework, but it is possible if rooting the device is an option for you:
Root device
Install and run Busybox
Install HideBar
In HideBar there is an option to run in 'Kiosk' mode, in which there is no way to re-display the navigation bar. Needless to say, you really need to be careful with this.
