After a day and a half of modification I've finally gotten the VLC project to almost compile under OS X. I get the following error when its just about to link libvlcjni.so. There are roughly 100 more undefined references, but most are to few functions:
std::__stl_throw_length_error(char const*)
std::__node_alloc::_M_deallocate(void*, unsigned int)
Has anyone got any pointers?

Try to include these lines into your Application.mk:
APP_CPPFLAGS += -frtti
APP_CPPFLAGS += -fexceptions
You have to explicitly enable the RTTI and Exceptions handling.
EDIT (response to your modifications):

I'm new with Android so I don't fully understand how to make Android.mk files.
My project was running fine, following a tutorial online where the Android.mk was provided. But later on I needed to add a missing library and the tutorial for that had another Android.mk, now I'm trying to merge the two together.
Here is my Android.mk :
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
#opencv
OPENCVROOT:= C:\OpenCV-2.4.10-android-sdk
OPENCV_CAMERA_MODULES:=on
OPENCV_INSTALL_MODULES:=on
OPENCV_LIB_TYPE:=SHARED
include ${OPENCVROOT}/sdk/native/jni/OpenCV.mk
LOCAL_SRC_FILES := com_example_adrien_ndkopencvtest4_OpencvNativeClass.cpp
LOCAL_LDLIBS += -llog
LOCAL_MODULE := MyOpencvLibs
include $(BUILD_SHARED_LIBRARY)
Here is the Android.mk I need to add :
LOCAL_PATH := $(call my-dir)
OPENCV_PATH := D:/CODE/OpenCV-2.4.10-android-sdk/sdk/native/jni
include $(CLEAR_VARS)
LOCAL_MODULE := nonfree
LOCAL_SRC_FILES := libnonfree.so
include $(PREBUILT_SHARED_LIBRARY)
include $(CLEAR_VARS)
OPENCV_INSTALL_MODULES := on
OPENCV_CAMERA_MODULES := off
include $(OPENCV_PATH)/OpenCV.mk
LOCAL_C_INCLUDES := \
$(LOCAL_PATH) \
$(OPENCV_PATH)/include
LOCAL_SRC_FILES := \
nonfree_jni.cpp
LOCAL_MODULE := nonfree_demo
LOCAL_CFLAGS := -Werror -O3 -ffast-math
LOCAL_LDLIBS := -llog -ldl
LOCAL_SHARED_LIBRARIES += nonfree
include $(BUILD_SHARED_LIBRARY)
What I'm interested in in the last Android.mk is the libnonfree.so only, I don't need the cpp file.
Here is the structure of my project :
EDIT :
Thanks for your answers. I've done what was suggested and my Android.mk looks like that now :
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
#opencv
OPENCVROOT:= C:\OpenCV-2.4.10-android-sdk
OPENCV_CAMERA_MODULES:=on
OPENCV_INSTALL_MODULES:=on
OPENCV_LIB_TYPE:=SHARED
include ${OPENCVROOT}/sdk/native/jni/OpenCV.mk
LOCAL_SRC_FILES := com_example_adrien_ndkopencvtest4_OpencvNativeClass.cpp
LOCAL_LDLIBS += -llog
LOCAL_SHARED_LIBRARIES += nonfree
LOCAL_MODULE := MyOpencvLibs
include $(BUILD_SHARED_LIBRARY)
include $(CLEAR_VARS)
LOCAL_MODULE := nonfree
LOCAL_SRC_FILES := libnonfree.so
include $(PREBUILT_SHARED_LIBRARY)
But the problem remains. I've got "Undefined reference" to methods libnonfree.so should add. I assumed the problem was from the Android.mk but maybe it's from elsewhere then.
I've added System.loadLibrary("nonfree"); to my MainACtivity and
#include "opencv2/nonfree/nonfree.hpp"
#include "opencv2/nonfree/features2d.hpp"
I don't know what I'm doing wrong.
EDIT 2 :
Here is the error :

SOLUTION :
My libnonfree.so file was not correct, I downloaded another one. I also changed my Application.mk file to :
APP_STL := gnustl_static
APP_CPPFLAGS := -frtti -fexceptions
APP_ABI := armeabi-v7a
APP_PLATFORM := android-16
If you want to add a prebuilt shared library to your project, you don't need a separate Android.mk
Let's take your script,
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
#opencv
OPENCVROOT:= C:\OpenCV-2.4.10-android-sdk
OPENCV_CAMERA_MODULES:=on
OPENCV_INSTALL_MODULES:=on
OPENCV_LIB_TYPE:=SHARED
include ${OPENCVROOT}/sdk/native/jni/OpenCV.mk
LOCAL_SRC_FILES := com_example_adrien_ndkopencvtest4_OpencvNativeClass.cpp
LOCAL_LDLIBS += -llog
LOCAL_MODULE := MyOpencvLibs
include $(BUILD_SHARED_LIBRARY)
and simply add to the bottom the extra module you need:
include $(CLEAR_VARS)
LOCAL_MODULE := nonfree
LOCAL_SRC_FILES := libnonfree.so
include $(PREBUILT_SHARED_LIBRARY)
Now the file C:\Users\Adrien\AndroidStudioProjects\NDKOpencvTest4\app\src\main\jni\libnonfree.so will be packed into your APK.
If you need this library to link your libMyOpencvLibs.so (this means, if your code in com_example_adrien_ndkopencvtest4_OpencvNativeClass.cpp uses some functions exported from libnonfree.so, you should also refeence it in your module:
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
#opencv
OPENCVROOT:= C:\OpenCV-2.4.10-android-sdk
OPENCV_CAMERA_MODULES:=on
OPENCV_INSTALL_MODULES:=on
OPENCV_LIB_TYPE:=SHARED
include ${OPENCVROOT}/sdk/native/jni/OpenCV.mk
LOCAL_SRC_FILES := com_example_adrien_ndkopencvtest4_OpencvNativeClass.cpp
LOCAL_LDLIBS += -llog
LOCAL_SHARED_LIBRARIES += nonfree
LOCAL_MODULE := MyOpencvLibs
include $(BUILD_SHARED_LIBRARY)
include $(CLEAR_VARS)
LOCAL_MODULE := nonfree
LOCAL_SRC_FILES := libnonfree.so
include $(PREBUILT_SHARED_LIBRARY)
Modify your android.mk as:
LOCAL_PATH := $(call my-dir)
OPENCV_PATH := D:/CODE/OpenCV-2.4.10-android-sdk/sdk/native/jni
include $(CLEAR_VARS)
LOCAL_MODULE := nonfree
LOCAL_SRC_FILES := libnonfree.so
include $(PREBUILT_SHARED_LIBRARY)
include $(CLEAR_VARS)
#opencv
OPENCVROOT:= C:\OpenCV-2.4.10-android-sdk
OPENCV_CAMERA_MODULES:=on
OPENCV_INSTALL_MODULES:=on
OPENCV_LIB_TYPE:=SHARED
include ${OPENCVROOT}/sdk/native/jni/OpenCV.mk
LOCAL_SRC_FILES := com_example_adrien_ndkopencvtest4_OpencvNativeClass.cpp
LOCAL_SHARED_LIBRARIES += nonfree
LOCAL_LDLIBS += -llog
LOCAL_MODULE := MyOpencvLibs
include $(BUILD_SHARED_LIBRARY)
Here the prebuild library i.e. libnonfree.so is declared in the android.mk, and referenced to it later via
LOCAL_SHARED_LIBRARIES += nonfree
Now to use it you need to load the latest built library in yout MainActivity i.e.
System.loadLibrary("MyOpencvLibs");
Thats it, now you have merged both the android.mk files into a new module named: MyOpencvLibs
For better understanding you can read my blog : https://androidtutsweb.wordpress.com/2017/04/04/android-mk-for-ndk-build-using-pre-build-libraries/

it seems that I have successfully linked the library for .cpp files, but there are errors show like this link
Does anyone know how to resolve this problem? Thanks.
PS There is similar question on Point Cloud Library (PCL) Users mailing list(www.pcl-users.org/Undefined-reference-to-PCDWrite-and-PCDWriteASCII-td4043323.html), but still no answer.
PS2 Or anyone can provide some instructions for using PCL in Android Studio?
Edit
I modified my Android.mk file here

If I add the line below in Android.mk, errors will not occur and can compile success
LOCAL_ALLOW_UNDEFINED_SYMBOLS := true
But when run the .apk, Android Monitor shows
java.lang.UnsatisfiedLinkError: dlopen failed: library "libtango_client_api.so" not found
During running build_native.py i get error "ExtensionMacros.h" no such file or directory.
The file itself is in cocos2d\extensions. I edited android.mk and uncommented line resposnsible for including this file. Why wont it find it?
Here is my android.mk:

and the top of error source cpp file :

#include "extensions/cocos-ext.h" //<---- this file includes "extensionMacros.h"
USING_NS_CC;

Does cocos2d/extensions/Android.mk have the line?
LOCAL_C_INCLUDES := $(LOCAL_PATH)/..
https://github.com/cocos2d/cocos2d-x/blob/v3/extensions/Android.mk#L40
It needs to find the header file.
how to call a c function in the C++ function with the same name?
calling 'extern "c"' to use c header and "::"operation to use the c function,
but the link error occur.
my code:
extern "C" {
#include <libavcodec/avcodec.h>
}
...
class DllAvCodec
{
public:
...
virtual void av_free_packet(AVPacket *pkt) { ::av_free_packet(pkt); }
...
}
the error:
D:/player/jni/lib/DllAvCodec.h:143: error: undefined reference to 'av_free_packet(AVPacket*)'
why the code "::av_free_packet(pkt)" invoke undefined?
my Android.mk is :
