Hi all? I developed on android?I want to add some function in pjsua2, I do it like that: 1. add declarations in hpp file. e.g, add ? int testFunc();? in pjsip/include/pjsua2/media.hpp 2. add function in cpp file. e.g,add ?int Media::testFunc(){return 100;}? in pjsip/src/pjsua2/media.cpp then,I follow these steps to build pjsua2 sample application: $ cd /path/to/your/pjsip/dir $ cd pjsip-apps/src/swig $ make I get the libpjsua2.so, but when i running pjsua2 sample application,I get a crash? 05-21 13:40:52.924: E/AndroidRuntime(9410): Caused by: java.lang.UnsatisfiedLinkError: Cannot load library: soinfo_relocate(linker.cpp:980): cannot locate symbol "_ZNK2pj5Media11getTypeTestEv" referenced by "libpjsua2.so"... What steps do I miss?? Best Regards, jason.chen -------------- next part -------------- An HTML attachment was scrubbed...
