    <p>I've sucessfully compiled jNetPcap as a shared library for Android. I have made a simple application using this code: <a href="http://jnetpcap.com/examples/classic" rel="noreferrer">http://jnetpcap.com/examples/classic</a> to test the API.</p> <p>The problem is that when I call the method findAllDevs and exception is raised with this message: "Can't read list of devices, error issocket: Permission denied"</p> <p>I cannot understand the reason, since I have made a call in the first part of my program so as to get root permissions for my application and I test my application to a rooted phone. When I run the application, a pop up is raised with this message:"SnifferApp has been granted Superuser permissions" and then the exception occurs.</p> <p>Any ideas?</p> <p>Here is a piece of my code:</p> <pre><code>Process p = Runtime.getRuntime().exec("su"); /*try { Thread.sleep(10000); } catch (InterruptedException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } // do nothing for 1000 miliseconds (1 second) */ try { System.loadLibrary(JNETPCAP_LIBRARY_NAME); } catch (UnsatisfiedLinkError e) { System.out.println("Native code library failed to load.\n" + e); } /*************************************************************************** * First get a list of devices on this system **************************************************************************/ int r = Pcap.findAllDevs(alldevs, errbuf); r = Pcap.findAllDevs(alldevs, errbuf); if (r == Pcap.NOT_OK || alldevs.isEmpty()) { tv.append("Can't read list of devices, error is" + errbuf .toString()); setContentView(tv); return; } </code></pre>

    1. COHi, I've the same problem with my application. I was able to install jnetpcap but when running the 'findAllDevs' function I receive an Empty List, no errors in errbuf... I was wondering if you have solved the problem? I am already running the applicaiton as root: $sudo -i -> root#eclipse -> start the AVD in eclipse

    2. COI didn't solved it at all. Finally, I used native code to run my experiments.. If I find something I'll let you know.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
