for API 32 android studio emulator you can change "Gesture Navigation" to "3 Button Navigation" or "2 Button Navigation", because it's sometimes has problems with scrolling drawerLayout

Settings -> System -> Gestures -> System Navigation enter image description here

Just change hw.mainKeys to yes in config.ini file.

1- Open config.ini file (To find file in your system follow steps below).

enter image description here

2- Don't forget to restart your emulator.

For lvl 30

window.decorView.windowInsetsController?.hide(android.view.WindowInsets.Type.statusBars())

Below 30

window.decorView.systemUiVisibility = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION or View.SYSTEM_UI_FLAG_FULLSCREEN

Is there a way to stretch the controls to the bottom of the screen if I hide my navigation bar? I have an ImageView with the height set to match_parent but the absent navigation bar leaves a black rectangle.

The easiest way to take a screen shot without the bottom navigation bar is to use an emulator (AVD) and edit its config file.

Go to .android/avd/virtual-device.avd

Then edit the config.ini:

hw.mainKeys=yes
hw.keyboard=yes

Both should be set to "yes"

In order to be able to see the bar again, set them back to "no".

Yes you can by using this in your activity :

@Override
public void onWindowFocusChanged(boolean hasFocus) {
        super.onWindowFocusChanged(hasFocus);
    if (hasFocus) {
        decorView.setSystemUiVisibility(
                View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                | View.SYSTEM_UI_FLAG_FULLSCREEN
                | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);}
}

In addition to Aykut Burak SAFAK's answer above, you can put his code in onWindowFocusChanged event to make sure that whenever the Activity gets focus (e.g. after unlocking) it retains fullscreen without soft keys state.

@Override
public void onWindowFocusChanged(boolean hasFocus){
    super.onWindowFocusChanged(hasFocus);
    getWindow().getDecorView().setSystemUiVisibility(
            View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                    | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                    | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                    | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                    | View.SYSTEM_UI_FLAG_FULLSCREEN
                    | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
}

getWindow().getDecorView().setSystemUiVisibility(
                View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                | View.SYSTEM_UI_FLAG_FULLSCREEN
                | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);

use this code in onCreate. But this requires api lv over 19.

If you only want to make the navigation bar (the button bar) less distracting, try youractivity.getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LOW_PROFILE)

I think this is possible

To hide the softkey Try getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION); but it is not working on tablet 4+.

You cannot hide it permanently, however:

getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);

this code hides the soft keys until the user interacts with your app. This is intentionally designed this way, just imagine, you don't provide any mean to exit from the current screen and hide theese keys, the user would be "trapped" in a one-way dead end.

To enable / disable them, as far as I know you simply have to edit the build.prop:

qemu.hw.mainkeys=0 (show on screen buttons)

or

qemu.hw.mainkeys=1 (disable on screen buttons)

If the line does not exist in your build.prop, add it at the bottom.
