PDAF gets defocus from PDAF Library and notify defocus to HybridAF.
HybridAF controls PDAF and ContrastAF to get fine focus in short time.
Software components of PDAF, ContrastAF and HybridAF are assumed to be

Please build PDAF Library on your environment in which you want.

The following example is simple "Application.mk" and "Android.mk"
to build shared library on Android NDK.
Please put PDAF Library source code and "Application.mk" and "Android.mk"
on same directory named "jni".
And command "ndk-build".

#Application.mk 
APP_ABI        := arm64-v8a 
APP_OPTIM      := release 
APP_PLATFROM   := android-23   # Android 6.0  

#Android.mk  
include $(CLEAR_VARS)  
LOCAL_PATH        := .  
LOCAL_MODULE      := PdafLibrary  
LOCAL_SRC_FILES   := PdafLibrary.c PdafMathfunc.c  
include $(BUILD_SHARED_LIBRARY)
