Including PCL with Android Stduio

I built PCL library for Android with
hcteq.wordpress.com/2014/07/14/compiling-pcl-for-android-in-windows-cmake-gui
I tried to include these library in Android Studio with Project github.com/roomplan/tango-examples-java/tree/master/PointCloudJava_with_PCL
To write .mk and .gradle file, I referred
stackoverflow.com/questions/35491012/issue-running-pcl-library-with-android-project
github.com/kalectro/pcl_groovy/blob/master/mobile_apps/android/OpenNIRecorder/jni/Android.mk

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

Building native OpenCV using Android NDK gives "undefined reference to 'cv::String::deallocate()'"

I'm attempting to use OpenCV with the NDK in Android Studio. As you may notice I'm using another native library called GStreamer.

I'm using OpenCV-3.1.0-android-sdk, NDK r10e, Android Studio 2.1, Windows. I've tried using a different version of OpenCV (2.4.11) but it didn't help.

I ran into a similar issue a few days ago. Imo, you should try to replace LOCAL_LDLIBS := -llog -landroid with LOCAL_LDLIBS += -llog -landroid.

The explanation for these errors is that the OpenCV code being used in GStreamer doesn't have access to the rest of the library, so it's failing to find basic methods like allocate() and deallocate().
The solution was to include some prebuilt static libraries in the Android.mk so that these references are defined. So after include $(OPENCV_ROOT_ANDROID)/sdk/native/jni/OpenCV.mk I added these lines to add the relevant libraries:
include $(CLEAR_VARS)
LOCAL_MODULE := opencv-tbb
LOCAL_SRC_FILES := opencvLib/3rdparty/libs/$(TARGET_ARCH_ABI)/libtbb.a
include $(PREBUILT_STATIC_LIBRARY)
include $(CLEAR_VARS)
LOCAL_MODULE := opencv-core
LOCAL_SRC_FILES := opencvLib/$(TARGET_ARCH_ABI)/libopencv_core.a
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/opencvLib/include/
LOCAL_STATIC_LIBRARIES := opencv-tbb
include $(PREBUILT_STATIC_LIBRARY)
include $(CLEAR_VARS)
LOCAL_MODULE := opencv-imgproc
LOCAL_SRC_FILES := opencvLib/$(TARGET_ARCH_ABI)/libopencv_imgproc.a
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/opencvLib/include/
LOCAL_STATIC_LIBRARIES := opencv-core
include $(PREBUILT_STATIC_LIBRARY)
The LOCAL_EXPORT_C_INCLUDESvariable sets the include files that correspond to that library. In this case the include folder works for both libraries.
Now for the GStreamer code to be able to use these libraries we have to add LOCAL_STATIC_LIBRARIES := opencv-core opencv-imgproc to the gstplayer module which references the 2 added OpenCV modules.
Edit:
Also I forgot to mention I changed APP_STL := gnustl_static to APP_STL := gnustl_shared in Application.mk

Android ndk ffmpeg : Unknown mnemonic error

I'm building a simple video app and want to embed a watermark on the recorded videos. I am using ffmpeg for this process and have successfully compiled it. The issue is when I try to link it with my project in Android Studio using ndk-build.cmd command, it gives me the following error:

First, I installed Cygwin64bit and added 'make', 'dos2unix', 'c++ gcc' packages. And I decompressed ffmpeg folder in C:/android-ndk-r11c/sources. This is the build script I used.

I ran this .sh in Cygwin(as administrator) but it didn't work. So I typed each of those lines on Cygwin and it compiled successfully. I tried both --target-os=android and --target-os=linux, but both didn't solve the problem above.
Then I followed this tutorial (enoent.fr/blog/2014/06/20/compile-ffmpeg-for-android/). Based on that, I made a native method in my project and built header file and c file.(To do that, I followed this video. youtube.com/watch?v=kFtxo7rr2HQ)
After that, I cloned this repo(github.com/HikoQiu/JNI_INVOKE_FFMPEG) and copied - pasted the jni folder into my project. And after making the Android.mk and Application.mk, I ran the C:/android-ndk-r11c/ndk-build.cmd in the Android Studio terminal and it gave me the error above.
These are the Makefiles I used.

Any ideas?

As the last line of your compilation error report says:
make: *** [obj/local/arm64-v8a/objs/myProject_Videokit/ffmpeg.o] Error 1
It's the key. You're trying to build your application for all available ABI's. As I can see your build.gradle file, there's no abiFilter. I'd do it in a next manner (I'm not sure with syntax, but the):
android {
...
ndk {
moduleName "com_example_myProjet_Videokit"
abiFilters = "x86", "armeabi"
}
...
}
If I were you, I'd use gradle-experimental plugin, prebuild ffmpeg libs for all needed ABI's, and then use this approach to load the libraries.
So the main problem - you have one library for all ABI's. It's incorrect.

Cocos2d-x Android build won't find extensions

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:
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
$(call import-add-path,$(LOCAL_PATH)/../../cocos2d)
$(call import-add-path,$(LOCAL_PATH)/../../cocos2d/external)

# $(call import-module,editor-support/spine)
# $(call import-module,editor-support/cocostudio)
# $(call import-module,network)
$(call import-module,extensions)
and the top of error source cpp file :
#include "World.h"
#include "U.h"
#include "Boxx.h"
#include "Globals.h"
#include "VisibleRect.h"
#include "extensions/cocos-ext.h" //<---- this file includes "extensionMacros.h"
USING_NS_CC;
USING_NS_CC_EXT;

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.

Problems compiling VLC for Android - libvlcjni.so

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):
