Navigation Bar Show/Hide

Show/Hide your navigation bar by Runtime Resource Overlay(RRO)

Android has a boolean for showing navigation bar or not. In frameworks/base/services/core/java/com/android/server/policy/PhoneWindowManager.java from AOSP, mHasNavigationBar got config from com.android.internal.R.bool.config_showNavigationBar and can be overwrited by property qemu.hw.mainkeys.

In the past, all tours tells people using qemu.hw.mainkeys to show/hide navbar, but I found that some apps/games will not hide the bar while in fullscreen mode. So I think using this way is better.

This overlay will overwrite config_showNavigationBar from framework.

Instructions

  • Installer will detect if your device has navbar or not. If you has that then it will install the hidden one.
  • The detect script can be found here.
  • I only test in 8.0/8.1, but RRO should work after 7.0.
  • If it didn’t effect, that means your rom didn’t support it or it add a whitelist for overlay apps.
  • If you want to disable hardware key (HOME, BACK, APP_SWITCH), copy your keylayout config from /vendor/usr/keylayout to $MODDIR/system/vendor/usr/keylayout and delete the line has HOME, BACK, APP_SWITCH.
