Re: pjsua2 crash in endpoint.libCreate Android

After further debugging it seems LibCreate is crashing in the function “attach_jvm”. It seems the variable pj_jni_jvm is not defined.
In googling possible reasons, the only solution that was posted to make sure the config_site.h is properly defined for android which in my case it is:

#define PJ_CONFIG_ANDROID 1
#include <pj/config_site_sample.h>

Does anybody have any suggestions on what could be causing this?

Regards

Hi,

I have been trying to integrate pjsip into my Xamarin.Forms app. I have successfully gotten the iOS version to work, but have been facing a crash on the Android version and have not found a solution for it. I tried all pjsip versions from 2.6 to 2.10 with the same issue. I also went back to the sample pjsua2xamarin application and I get the same crash. 

Crash log:
[Mono] Found as 'CSharp_pjsua2xamarinfpjsua2_Endpoint_libCreate___'.
[libc] Fatal signal 11 (SIGSEGV), code 1, fault addr 0x0 in tid 30101 

What I have done:
1. Followed instructions in ticket 2086.
2. Followed pjsip instructions on how to build for Android https://trac.pjsip.org/repos/wiki/Getting-Started/Android <https://trac.pjsip.org/repos/wiki/Getting-Started/Android>
3. Added the following android permissions in Manifest just to be comprehensive since ticket 2086 mentions that crash in the initialization phase is most probably related to permissions:
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.RECORD_AUDIO" />
    <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.WAKE_LOCK" />
    <uses-permission android:name="android.permission.VIBRATE" />
    <uses-permission android:name="android.permission.USE_SIP" />
    <uses-permission android:name="android.permission.CAMERA" />
4. I?m trying to run in an emulator and android sdk version 22, so I don?t have to worry about requesting permissions

5. I have also tried different ndk versions from r13b to r20 and tried targeting various android sdk levels

6. I used the following configure parameters: APP_PLATFORM=android-18 TARGET_ABI=x86 ./configure-android --use-ndk-cflags --disable-video

I?m not sure what I can do to debug this issue. Has nay body ran into this issues? Any suggestions on what I can do/try next?

Regards
Dirar
