Create Module to Support S.I.S

You have already learned Decompiling and Recompiling SystemUI

• Now to create S.I.S Module
• In my provided files
• in toMerge folder , Copy layout and drawable folder and paste it to your SystemUI_src/res/HERE (dont create a folder called here)
• in toCompare Compare S.I.S layout to your SystemUI_src

How to properly compare:
open 2 files

file 1: a file from the "ToCompare" folder
file 2: a file with the same name from your /res/layout folder

search for "Compare start" in the "ToCompare" file
check if your file looks the same as the "ToCompare" file

do this until you reach "Compare stop"



Repeat for all files in the "ToCompare" folder

*Note Compare not Replace!

• Now Recompile!

Replacing

• In your Zarchiever
• Open SystemUI_src.apk
• select all the modified res (files you modded) copy and replace the files inside of:
• S.I.SvrTheme[MAGISK].zip vrtheme/system/system_ext/priv-app/SystemUI/Systemui.apk/res/HERE
• now install your S.I.SvrTheme[MAGISK].zip in your Magisk
• And Enjoy S.I.S A11 (you can also edit module.prop to change name, ID, and other things about the module)
