Licode Android Client issue - can not open camera

When trying to use the licodeAndroidClient from:

Got an error that:
Fatal error: Failed to open capturer

It seems the issue is related to either the webRTC shared library or
licode related interface.

Questions:
how does the next two files get compiled?
Where is the source code?
libjingle_peerconnection.jar
libjingle_peerconnection_so.so

Does anyone know that?

Currently Chrome for Android and the general Chrome practically share all functionality. Therefore this type of problem is quite unusual.

At least I have not encountered any such problems with Android. We are, however, using Cordova. The Cordova interface to Android uses the complete Chromium-kit. No problems this far.

But we are using a Cordova generated app at the Android side.
