As per my observation, crash occurs due to line "peer.pc.dispose()" from onDestroy() method of WebRtcClient class.
public void onDestroy() {
for (Peer peer : peers.values()) {
peer.pc.dispose(); -------- causing crash
}
videoSource.dispose();
factory.dispose();
client.disconnect();
client.close();
}

Please let me know fix for this.

update to "io.pristine:libjingle:9636@aar"

[victorileaf]

Done that . still issue persists. did someone find any solutions?
Any help would be appreciated!
i think factory.dispose) causes the issue.
anything related with PeerConnectionFactory.initializeAndroidGlobals()?

[alexruskovski]

the problem is still here... any solutions guys?

/*This Code Works in My Project/
public void onDestroy() {
for (Peer peer : peers.values()) {
peer.pc.dispose();
}
//videoSource.dispose();
factory.dispose();
client.off();
client.disconnect();
client.close();
}

[crazy-airhead]

using io.pristine:libjingle:11139@aar
at onDestroy() method
videoSource.stop(); //factory.dispose();
