PJSUA2 sip android native app

Here I'm developing an application using native android in ubuntu 14.04LTS eclipse adt for android.

Build, configure, and make everything went perfect.

After that I imported pjsua2 sample app into eclipse, I then added native library support but when I run on emulator it throws an error.

The error log,

回答1:

java.lang.UnsatisfiedLinkError: Couldn't load libpjsua2.so from loader dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/org.pjsip.pjsua2.app-2.apk"],nativeLibraryDirectories=[/data/app-lib/org.pjsip.pjsua2.app-2, /vendor/lib, /system/lib]]]: findLibrary returned null

I had the same error. The android sample app tries to load this libpjsua2.so from the JNILIBs folder path but it couldnt find it so it throws the above error.Hope my answer helps someone .

回答2:

I had the same problem. It seems you was building pjsip library using newest ndk. Try older version of ndk and rebuild pjsip.

回答3:

I followed this https://github.com/VoiSmart/pjsip-android-builder link to build the pjsip hope it would help others but still facing some problems in video calling related.
