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?

I tried all pjsip versions from 2.6 to 2.10 with the same issue.

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.
