Android how to programmatically hide launcher icon

Question

my app is designed to only need to be run once. As such I want to hide the icon from the launcher after the first run, but without uninstalling the app.

I have seen

Answer 1

PackageManager p = getPackageManager();
p.setComponentEnabledSetting(getComponentName(), PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);

Note that the icon may not be gone until the next reboot.
