How to read packets in Android using Jnetpcap?

Question

I am working on an Android app where I need to capture the packets. I am using VpnService for this purpose. I am able to write the data to a pcap file. Next I want to decode the pcap file. I am using jnetpcap library version 1.3 for this purpose. I am able to successfully load the library in my application. But when i loop the pcap object, it throws an exception. Has anyone used jnetpcap on Android before ? Are there are tutorials or code example for using jnetpcap in Android, that would be really helpful.
