How to shut down permantly one core on Android phone programatically

[GiorgosKanellis]

Good Afternoon.

I working on an Android application, but I'm stuck on a problem now. I want to shut down permantly one (or more) of the four CPU cores of my android device. I found a way through ADB but none through Java.:crying:

Can anyone help me out?
Thanks in advance!

What's the ADB command to do that? There should be a way to integrate some shell commands into java code.

Well I want this ADB piece of code into java in some way.

adb root
adb stop mpdecision
adb shell
echo "0" > /sys/devices/system/cpu/cpu1/online
echo "0" > /sys/devices/system/cpu/cpu2/online
echo "0" > /sys/devices/system/cpu/cpu3/online

Try using app kernel auditor mod I think it can do what you want

Thank you, but kernel adiutor or another kernel manager don`t apply changes since early boot (early init). It apply changes once the phone loads the rom and enters on launcher
I need modify kernel image boot.img or something similar

There is boot img which holds
Kernel img ram disk and one other img I can't remember the name of
A custom kernel may be required
