Hiding the Android system UI

7/2/2015

To hide/show the UI from with your app...
After a lot of searching on the internet, I managed to get the System Bar to hide and appear in a 4.2 device using the commands below
To Hide:

Runtime.getRuntime().exec("service call activity 42 s16 com.android.systemui");
Or use 79 instead of 42 for API less than 14.

To Show:

Runtime.getRuntime().exec("am startservice --user 0 -n com.android.systemui/.SystemUIService");

Great blog I enjoyed reading it

Unless stated otherwise, everything discussed herein is related to development I've done on semi custom hardware, (Freescale-based, derived from a FS reference platform) with a rooted BSP/OS (also based on a Freescale reference build). I have not built the BSP (nor have I ever built a BSP)
