Answer 1

The last information I have is that you can use the black tape to cover it. That's the suggestion given by Chet Haase. Watch this google IO 2011 session Q&A starting at 53minutes

Youtube app also dim it, not remove it. It is called light out mode.

View v = findViewById(R.id.view_id);
v.setSystemUiVisibility(View.STATUS_BAR_HIDDEN);

Answer 2

I use this code to hide the navigation bar and it works perfectly for me

View v = this.getWindow().getDecorView();

v.setSystemUiVisibility(View.INVISIBLE);

Answer 3

What you should do is set System Ui Visibility in onResume()

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

If you wont set it sticky bar will be visible again when touch screen will be occured

Answer 4

SYSTEM_UI_FLAG_HIDE_NAVIGATION flag can be used on a View to hide the navigation bar until a user interaction occurs, starting from Android API 14.

You should look at here and here.

Answer 5

This code will hide the navigation bar until you swipe down from the status bar. It's the same method that Jetpack Joyride uses:

View decorView = getWindow().getDecorView(); 
int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY;
decorView.setSystemUiVisibility(uiOptions);

You must also have this in the activity section of your XML file:

android:theme="@android:style/Theme.Holo.Light.NoActionBar.Fullscreen"

Answer 6

ActionBar actionBar = getActionBar();
actionBar.hide();

That will do the trick. Also check out the HoneycombGallery example which demonstrates this working.
