[Linphone-developers] Exception in build process of linphone github project

[Chandan Sharma]

Hi,

I download the code from github "git://git.linphone.org/linphone-android.git --recursive
" of linphone and compiled it with ndk but when i go to adroid tools->add native support then it will making files in jni folder. But i saw that no library files in libs folder, i think which creates exception(ExceptionInInitializerError) because System.loadlibrary can not find the libraries.

In class LinphoneCoreFactoryImpl at static block there is an exception at code 

/* it is lin phone  library avutil-linphone-x86*/

    // FFMPEG (audio/video)
                  if (Version.isX86()) {
                         loadOptionalLibrary("avutil-linphone-x86");
                         loadOptionalLibrary("swscale-linphone-x86");
                         loadOptionalLibrary("avcodec-linphone-x86");
                  } else if (Version.isArmv7()) {
                         loadOptionalLibrary("avutil-linphone-arm");
                         loadOptionalLibrary("swscale-linphone-arm");
                         loadOptionalLibrary("avcodec-linphone-arm");
                  }

actually call comes from this part :

private static boolean loadOptionalLibrary(String s) {
                  try {
                         System.loadLibrary(s);
                         return true;
                  } catch (Throwable e) {
                         Log.w("Unable to load optional library lib", s);
                         e.printStackTrace();
                  }
                  return false;
           }

Exception i got :

Please reply why this exception occurs, could be the reason is that the github project does not have libraries.
