Android NDK Superuser Permissions

Question

I have a C program that I can run with my Android root phone. However, for the program to work properly, the program must run as superuser.

Now I want to call a method from this program using the Android NDK interface. What should I do to make my own code work as superuser?

Answer 1

You must run the program su, and then script it (by writing to standard input) to run your program. On some rooted devices, this will “just work”, and on others (in most cases) it will trigger activity from the SuperUser application to ask the user if they are allowed.
