How to use FileObserver for System files [Android]
<p>I wan to monitor changes in android system file<br>
<code>"/sys/class/net/eth0/operstate"</code> for monitoring ethernet state.</p>

<p>I have written an File Observer class but i am not getting any events in 
<code>public void onEvent(int event, String path)</code> call back function.  </p>

<p>Do we need any special type of permissions for observing android system files?<br>
Do i need to run my APK as root.</p>

<p>Thanks.</p>
