I am working on custom screen lock app where we need to full screen view hiding the top and bottom bars completely. The app is for Android phones only and not tablets. I achieved this partially by using Immersive mode but the issue is the bottom bar & top appears for few seconds on touching bottom or top of the screen.
Below is the code in my activity to do this :
final int flags = 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(flags);
I have tried various options but unable to hide the bars permanently. Please advise.
