The Overlay pixel theme ported to all Andorid 8.0.
You have to install PixelThemeOverlay.apk and PixelNavBar.apk
PixelThemeOverlay = com.google.android.theme.pixel
PixelNavBar = com.botty.android.theme.pixel
Now you have to run the following commands for both apks:
$ adb shell $ cmd overlay list $ cmd overlay enable "PACKAGE NAME"
$ adb shell $ cmd overlay list $ cmd overlay disable "PACKAGE NAME"
If you install two or more theme for theming the Android UI ( it's called framework-res.apk ), like the PixelThemeOverlay, you have to choose it from the list in the settings app.
Like this..
If you will notice i've decompiled the PixelThemeOverlay for trying to make on my own. But for now it will crash the systemui so it will send your dvice in bootloop.
SO DO NOT COMPILE AND ENABLE THE PIXEL UI MODULE.
