android sdk3.1 have two org.webrtc .

Jar package structure:

libjingle_peerconnection.jar

META-INF

org.webrtc

woogeenbase.jar

com.intel.webrtc.base

META-INF

org.webrtc

Is it right?

[allen_w_]

Delete  

compile files('libs/libjingle_peerconnection.jar')

is  OK。

p2p sample running is ok now.
