you should not be able to implement what you want. That is totally not up to you to decide if user can exit your app. — Vladyslav Matviienko, Sep 18 '18 at 05:39

then you probably can gain a root access on that device, or use a kiosk mode. Or develop your app as a launcher app on it. — Vladyslav Matviienko, Sep 18 '18 at 05:50

@damithalahakoon, if your app is a generic 3rd-party app that any user can install from google play, even if you would be able somehow to implement what you want, your app will be treated as malicious, and likely removed from google play. – Vladyslav Matviienko Sep 18 '18 at 05:45

Try this:

View decor_View = getWindow().getDecorView();

int ui_Options = 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;

decor_View.setSystemUiVisibility(ui_Options);

But it need device android OS version is 4.4 or higher.
