Completely Disable/Hide Status Bar on 4.4.2

Question

We are developing a launcher app for elderly people which has a very easy UI and we do not want to show status bar or notification drawer.

Now i tried to disable Status Bar but it seems to re-appear when i pull down from the upper side of the screen. And if i pull-down for the second time notification drawer is opened. Is there a way to completely disable Status Bar?

I checked the documentation on the following links but i think no solution is present. In API level 16 we were able to disable it completely but not in api level 19. https://developer.android.com/training/system-ui/status.html#41

Answer 1

Try this. It hides status bar, bar with home, return buttons. I use it and it works for me on 4.4.2 AllWinner V11 tablet

Needs ROOT

Use this at your own risk

• After rooting install SuperSU and file manager app like ES file explorer.
• Grant access for ES explorer
• In ES settings check Root explorer then Mount RW
• In /system find build prop.build file
• At the end add qemu.hw.mainkeys = 1
• Save and exit, reboot.

This will hide the bottom bar with Return, Home, and Recent apps. No swipes or other interupts it. To show it again delete qemu.hw.mainkeys = 1 or make it 0
