At the Line

System.loadLibrary("gnustl_shared");

Thanks in Advance.

Answer 1

Using your install manager (Depending on your device like aptitude or homebrew or macports ) install gnustl and gnu related (like libstdc++6:i386 libgcc1:i386 zlib1g:i386 libncurses5:i386 ) which is needed for liblinphone

Refer : https://github.com/BelledonneCommunications/linphone-android#compilation-instructions

Couldn't find libtoolize, even though I have installed libtool in OSX Yosimite
