Problem reading system file in Android app, even with root
<p>I am writing an app to monitor some files under /sys/devices/.../cpu.  There is one file that is owned by root:root, with only read permissions for root.</p>

<p>I added code to exec("su"), but even then I get a file not found exception.  The only way I don't get an error is if I chmod the file permissions.  However, these permissions get set back to root read after boot, so I'd really like to find how to do the read without changing the file perms.</p>

<p>Thanks,
Jim</p>
