PeerConnectionFactory(options) on Android is crashing

[samfast]

Hello,

I compiled the webrtc for android (version : 16518) and upgraded my application to use new version. However, when I try to create object of PeerConnectionFactory, I get following error and app crashes. 

E/rtc: #
       # Fatal error in ../../webrtc/modules/utility/source/jvm_android.cc, line 236
       # last system error: 0
       # Check failed: g_jvm
       #
       #

This is how I am trying to do this:

PeerConnectionFactory.initializeAndroidGlobals(getApplicationContext(), false, false,
 false);

PeerConnectionFactory.Options options = new PeerConnectionFactory.Options();

factory = new PeerConnectionFactory(options);

I am trying to create peer connection for datachannel only, therefore, I have set other parameters to false in initializeAndroidGlobals().

When I compiled, I got so files for following architectures:

arm64-v8a
armeabi-v7a
x86
x86_64
I got the following two jar files:
base_java.jar
libjingle_peerconnection.jar
I have tried many things but couldn't resolve this error.

Previously, I used version 8871.

Thanks.

Does it work if you call PeerConnectionFactory.initializeAndroidGlobals(getApplicationContext(), true, true, true) instead?

My guess is that your app needs to be able to initialize audio and video as well.

Thanks for reply Henrik.

When I send all variables as true, I get error in another file. Here is the error that I get:

E/rtc: #

         # Fatal error in ../../webrtc/modules/utility/source/helpers_android.cc, line 68

         # last system error: 2

         # Check failed: !jni->ExceptionCheck()

         # Error during FindClass: org/webrtc/voiceengine/BuildInfo

         #

I am still experimenting with the code. I have also added following lines in my code:

PeerConnectionFactory.initializeFieldTrials("Test");
PeerConnectionFactory.initializeInternalTracer();
PeerConnectionFactory.initializeAndroidGlobals(getApplicationContext(), true, true,
 true);
PeerConnectionFactory.shutdownInternalTracer();

PeerConnectionFactory.Options options = new PeerConnectionFactory.Options();

factory = new PeerConnectionFactory(options);

I am following the comments in the following file in order to do my code:

I have just read the other thread. I also compiled library using the automated script pristine.io. Should I rebuild the library? If pristine is outdated, is there any other set of instructions which are complete and also tell what are the required jars that we need to make. The instructions on webrtc.org are not in order so it is very difficult to follow them. Please guide.

If u built the webrtc from latest branch you should see a jar file named "audio_device_java.jar", import that jar, the error will be cleared!
