Which method is the missing one in this "NoSuchMethod" exception?

Question

I am getting the following exception for "NoSuchMethod" :

However, I don't quite understand which method is the problem. Is it org.jnetpcap.Pcap.loop?

What's the code where you get this? – EboMike Aug 16 '11 at 19:22 — EboMike, Aug 16 '11 at 19:22
Can we look at the culprit code? – Kal Aug 16 '11 at 19:25 — Kal, Aug 16 '11 at 19:25

It actually looks to be in that invocation of Thread.run -- check your arguments. If they don't match the signature of Thread.run you would get that error, I beleive.

Seems like the org.jnetpcap.* was written for J2SE - it's looking for java.awt.Image. AWT does not exist in the Android API out of the box.

There are solutions available to use AWT (or Swing) on Android.
