How to run Linux commands in my Android app?

Question

I want to run a Linux command in my Android app. I mean I'm an Android programmer and I want to commit a command in my codes in Java which I'm writing in Android Studio.

For example this is what I want in my codes in Java in Android Studio:

ImaginarylinuxClass.theFunctionWhichRunsTheCommands("sudo apt-get update && git clone  && etc");

I hope I was able to say what I mean.

I tried to Google about it but it was all apps which they are Linux emulators like termux but it's not what I want actually.

Test this code man:

try {
    Runtime.getRuntime().exec("cd sdcard/");
} catch (Exception e) {
    showMessage(e.toString());
}

Replace "cd sdcard/" for your Linux commands...
