Hi, I am prototyping an application using pjsip on the Android platform. I use https://svn.pjsip.org/repos/pjproject/tags/2.7.2, pjsua2 high level APIs (Java). I encountered a problem while debugging my application. - The application process aborts. - It occurs in the first callback (e.g. onCallState). - The address where the exception occurs is in the native library. (e.g.) ----- android's logcat --------------- 06-12 20:35:13.215 I/crash_dump64(19482): performing dump of process 19390 (target tid = 19410) 06-12 20:35:13.215 F/DEBUG (19482): *** *** *** *** ***

Attach the code difference added to the mother code of pjsip 2.7.2. I will write my opinion below: 1. some pjsua2's C++ constructor does not initialize basic type data member. 2. If it is an enum mapping of SWIG, SWIG will throw an exception. C ++ does not implicitly initialize basic types (ZERO overhead rule). I think that the default constructor should be initialized so that an undefined value does not occur. Best regards
