error building pjsua with android-ndk-r9

Question

I am using android-ndk-r9

When I try to compile pjsua android sample http://goo.gl/sg621z I get the following error:

Android NDK: WARNING:jni/Android.mk:pjsua: non-system libraries in linker flags: -    lpjsua-arm-unknown-linux-androideabi -lpjsip-ua-arm-unknown-linux-androideabi -lpjsip-simple-arm-unknown-linux-androideabi -lpjsip-arm-unknown-linux-androideabi -lpjmedia-codec-arm-unknown-linux-androideabi -lpjmedia-videodev-arm-unknown-linux-androideabi -lpjmedia-arm-unknown-linux-androideabi -lpjmedia-audiodev-arm-unknown-linux-androideabi -lpjmedia-arm-unknown-linux-androideabi -lpjnath-arm-unknown-linux-androideabi -lpjlib-util-arm-unknown-linux-androideabi -lresample-arm-unknown-linux-androideabi -lmilenage-arm-unknown-linux-androideabi -lsrtp-arm-unknown-linux-androideabi -lgsmcodec-arm-unknown-linux-androideabi -lspeex-arm-unknown-linux-androideabi -lilbccodec-arm-unknown-linux-androideabi -lg7221codec-arm-unknown-linux-androideabi -lpj-arm-unknown-linux-androideabi -lgcc -lgcc    
This is likely to result in incorrect builds. Try using LOCAL_STATIC_LIBRARIES or LOCAL_SHARED_LIBRARIES instead to list the library dependencies of the    
current module    
Invoking SWIG...

Before performing ndk-build command, please do the following steps

cd pjsip-apps/build make pjsua

then perform ndk-build in /pjsip-apps/src/pjsua/android directory

have a look at the following blog
