Hide Android Navigation Bar in React Native
Solution 1
If you're looking to achieve this permanently you'll have to hide the Navbar when the app is created and when it comes back into focus.
To do so, add this in your MainActivity.java
:
...
import android.os.Bundle;
import android.view.View;
public class MainActivity extends ReactActivity {
...
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
hideNavigationBar();
}
@Override
public void onWindowFocusChanged(boolean hasFocus) {
super.onWindowFocusChanged(hasFocus);
if (hasFocus) {
hideNavigationBar();
}
}
private void hideNavigationBar() {
getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
}
}
You may want to make it "immersive" so that the user can still access the navigation bar by pulling from the bottom of the screen.
To do so, add the View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
flag:
...
import android.os.Bundle;
import android.view.View;
public class MainActivity extends ReactActivity {
...
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
hideNavigationBar();
}
@Override
public void onWindowFocusChanged(boolean hasFocus) {
super.onWindowFocusChanged(hasFocus);
if (hasFocus) {
hideNavigationBar();
}
}
private void hideNavigationBar() {
getWindow().getDecorView().setSystemUiVisibility(
View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
}
}
You can find more options on the android documentation.

To hide the Android Navigation bar you can do that using react-native-navigation-bar-color
it allows you to show or hide the navigation bar. You can see more in the documentation [here][1]. Note that it will not work on Expo as it requires you to link native code.
Installation is fairly straight forward:
npm install react-native-navigation-bar-color --save
Then you need to link the package:
react-native link react-native-navigation-bar-color
Once you have done that you can use it in the following way:
import {
HideNavigationBar,
ShowNavigationBar,
} from 'react-native-navigation-bar-color';
Then when you want to show the navigation bar you just use
ShowNavigationBar();
And to hide it you can use:
HideNavigationBar();

Building off of Martin Konicek's answer:
I went ahead and wrote the Package and Module you need here: https://gist.github.com/dhrrgn/16a8dfa7581a682627c6
You need to add it in your MainActivity.java
file in the getPackages
method, and send the package the ReactActivity object like this: new NavigationBarAndroidPackage(this)
Note: The code is untested, but it should work for you (you need to change the package
on the first line). I just used the example code provided in the link you sent as an example. Modify to your needs.
Solution 4
I've created a package with navigation bar hide/show, color change and more.
react-native-system-navigation-bar
Install
yarn add react-native-system-navigation-bar
or
npm install react-native-system-navigation-bar

Solution 5
There is no built-in API to do this from JavaScript.
The good news is in React Native you can expose any native functionality to JavaScript, by writing a native module. See documentation.
This way you can provide a JS function like NavigationBarAndroid.hide()
and make it call the API you linked to.

How can I hide the Android Navigation Bar in React Native?
I'm referring to the bar at the bottom of the screen that has the software back button and home button, not the component at the top of the page that comes with the Navigator Component.
This page on android.com explains how to do it for native developers. Can someone explain how to accomplish this via React Native apps? Thanks.
