libjingle - Android AppRTCDemo example - native crashs

[mparis]

Hi, I have a SIGSEGV signal when I run AppRTCDemo example provided in libjingle project.

I am using the revision r305 of libjingle and I followed the instruction of README under /trunk/talk/examples/android dir.
I also had to do the next steps because following only the README i couldn't compile libjingle_peerconnection_so.so :

•  set 'libjingle_java' to 1 in trunk/talk/build/common.gypi line 38

•  set correct JDK path in trunk/talk/libjingle.gyp line 61

•  export GYP_GENERATORS='ninja'

Moreover, I had to add the next include in peerconnection_jni.c because Constraint struct couldn't be found.
#include "talk/app/webrtc/mediaconstraintsinterface.h"

After all this, I got compile libjingle_peerconnection_so.so and build the AppRTCDemo, but now I have a SIGSEGV in this library when I run the APP on nexus 4.
I obtain the next backtrace:
04-16 11:24:31.443: I/DEBUG(158): backtrace:
04-16 11:24:31.443: I/DEBUG(158):     #00  pc 0001a772  /system/lib/libc.so

Using addr2line I can see that this the line that crashed is 713 in peerconection_jni, when CHECK_EXCEPTION(jni(), "error during CallVoidMethod"); is executed:
0x0002f47b
OnComplete
peerconnection_jni.cc:713
0x000a3c07
webrtc::PeerConnection::OnMessage(talk_base::Message*)
peerconnection.cc:628
0x00069dc9
talk_base::MessageQueue::Dispatch(talk_base::Message*)
messagequeue.cc:368
0x0006955d
talk_base::Thread::ProcessMessages(int)
thread.cc:511
0x00069793
talk_base::Thread::PreRun(void*)
thread.cc:356

How can I solve this issue?

Thanks in advance!!
