How to completely exit from Immersive full screen mode?

Question

I would like to implement a button to enable/disable the immersive full screen mode. I\'m using those methods but the showSystemUI only shows quickly and hide again...

Answer 1

What worked for me is the following:

View decorView = activity.getWindow().getDecorView();
decorView.setSystemUiVisibility(0);

I might be wrong but it seems like calling setSystemUiVisibility with 0 clears the flags which were previously applied.
