Hi Developers,
I have an application which consists of the native part and higher
layer.
Therefore, it needs to be granted the root privilege to run some
native functions.
As the article I post before, I added a piece of code taken from Bluez
Utils(hidd.c).
<code>
if (bind(sk, (struct sockaddr *) &addr, sizeof(addr)) < 0) {
close(sk);
return -1;
}
</code>
The code has been built to be a .so by NDK.
Unfortunately, It keeps returning -1 and errno is 13 which means
Permission Denied.
Some experienced developers(Thank you here) mentioned about that the
error happens because this application doesnt have enough permission.
It "SHOULD NOT" be something like
Process process = Runtime.getRuntime().exec("su");
I think this means you possess a system permission but your
application doesnt.
(Let me know if i am wrong)
Is there any way to grant the app for having the root privilege?
Any reply/clue/hint will be highly appreciated.
Regards-
Sam
