回答1:
It may happen for several reasons. First, check if you attached the native library correctly. For that create a folder named "jniLibs" into the projects
app/src/main/jniLibs
then put your armeabi architecture library like
armeabi/libpjsua2.so
for other architecture like armeabi-v7a use
armeabi-v7a/libpjsua2.so
like this.
there are other reasons may happen. If you build pjsip library for armeabi architecture only and running your application in an x86 architecture device then this error may occur. So check it also if you have built it for that application.

Please take a look at this thread: building pjsua2 dll
the important thing to know here is that the error you show in your question is caused by the fact that the pjsua2.dll (a c++ dll) is not in your output directory.
