Build opencv and tesseract for android-ndk

So I'm trying to build tesseract (using tess-two) and opencv for android. I'm able to build opencv and tess-two separately, but I want to be able to build them alongside.
For that I'm using the same build file as given in tess-two. Here all sub directory Android.mk files are called which works without a problem. As soon as I want to include the opencv library as well, and I want to compile files which are dependent on tesseract and opencv I get following errors.
Build command failed.
Error while executing process /home/alexander/Android/Sdk/ndk-bundle/ndk-build with arguments {NDK_PROJECT_PATH=null APP_BUILD_SCRIPT=/pathtoapp/app/src/main/cpp/Android.mk NDK_APPLICATION_MK=/pathtoapp/app/src/main/cpp/Application.mk APP_ABI=arm64-v8a NDK_ALL_ABIS=arm64-v8a NDK_DEBUG=1 APP_PLATFORM=android-24 NDK_OUT=/pathtoapp/app/build/intermediates/ndkBuild/debug/obj NDK_LIBS_OUT=/pathtoapp/app/build/intermediates/ndkBuild/debug/lib APP_SHORT_COMMANDS=false LOCAL_SHORT_COMMANDS=false -B -n}
Android NDK: WARNING:/pathtoapp/app/src/main/cpp/com_googlecode_tesseract_android/Android.mk:tess: non-system libraries in linker flags: -latomic
Android NDK: This is likely to result in incorrect builds. Try using LOCAL_STATIC_LIBRARIES
Android NDK: or LOCAL_SHARED_LIBRARIES instead to list the library dependencies of the
Android NDK: current module
I'm not really sure, why this error happens. As mentioned I'm able to build the libraries separately. So the problem must be bringing them together.
Here is my makefile:
Android.mk:
LOCAL_PATH := $(call my-dir)
TESSERACT_PATH := $(LOCAL_PATH)/com_googlecode_tesseract_android/src
LEPTONICA_PATH := $(LOCAL_PATH)/com_googlecode_leptonica_android/src

LOCAL_LDLIBS := -llog -landroid -lcamera2ndk -lmediandk
LOCAL_SHARED_LIBRARIES := libtess liblept
include $(BUILD_SHARED_LIBRARY)
My current build directory looks as following:
- com_googlecode_leptonica_android
- com_googlecode_tesseract_android
- libjpeg
- libpng
- opencv
Is there something that I'm doing wrong? The error message is saying, that I'm using a non-system libraries in linker flags: -latomic , but this seems to be not the true error.
Can anyone help me?
Edit:
I found out, what the eror was. It was no rule to make target native_lib.cpp. So I wasn't able to build the following cpp file. I fixed it by creating a temporary variable of my $(LOCAL_PATH).
LOCAL_PATH := $(call my-dir)
MY_PATH := $(LOCAL_PATH)
TESSERACT_PATH := $(LOCAL_PATH)/com_googlecode_tesseract_android/src

Now, I'm running into a new problem.

Now while it seems to not be able to find the compiled opencv library. What is the problem? Thanks for the help!

OpenCV 3.4.1 Android SDK static libraries dependencies

EDIT 2: Found the correct order, back to using static libs
libavutil libavcodec libavformat libswresample libswscale dnn ml objdetect shape stitching superres videostab calib3d features2d highgui videoio imgcodecs ilmimf jpeg jasper png tiff webp video photo imgproc flann core tegra_hal log cpufeatures z
EDIT 1: I gave up on this, and compiled the big SHARED_LIBRARY libopencv_world.so.
I'm trying to configure an Android Studio React Native project using OpenCV to be built with AppCenter.
I'm working on a mac. Because an agent (mac OSX in my case) will be provisioned for me to build my project in the cloud, all the code and static libraries dependencies should come from the source repository. AFAIK I can't use find_package() in my case because of this serverless environment, right?
I've downloaded the OpenCV Android SDK which contains everything I need to link with the static libraries.
My problem is that I need the OpenCV static libraries to be properly ordered for the link phase to complete. I can't find a complete properly ordered list of those libraries. But I found a way to tell the linker to figure it out.
Here is where I am so far. First the CMakeLists.txt file:
cmake_minimum_required(VERSION 3.4.1)
# CMAKE_SOURCE_DIR : this is the directory which contains the top-level CMakeLists.txt, i.e. the top level source directory. In this case the andoid/app folder.
# set OpenCV Static Libraries Environment Variables

to only include the libraries and the result is the same.

What is wrong with this approach?
Thanks for your help.

Build issue : Android Link Error with AWS SDK CPP

I build (static and dynamic)the AWS SDK CPP library on my PC for Android Applications. After that, I developped an Android Application with Qt 5.10 using this AWS CPP librairy but at the end, during the link, I have many errors. I tried on MacOS and Windows 10 but I have the same errors and I used the ANDROID NDK 12 because is the only working to build the AWS SDK CPP library.
I tried to solve it during 2 weeks. Please Someone could help me ?
Here is my command of the linker and the result :

Android NDK and STL-related reference errors on x86

I'm building an integration with the V8 library. This builds works fine for ARM (armeabi, armeabi-v7a) targets.
I want to add x86 support. Today is the first time I've tried this.
I built V8 for x86 via make ia32.release.
My Application.mk is as follows:
APP_ABI := armeabi armeabi-v7a x86
APP_PLATFORM := android-14
APP_STL := stlport_static
and Android.mk:
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := v8_libbase
LOCAL_SRC_FILES := ./libs/$(TARGET_ARCH_ABI)/libv8_libbase.a
include $(PREBUILT_STATIC_LIBRARY)
include $(CLEAR_VARS)
LOCAL_MODULE := v8_base
LOCAL_SRC_FILES := ./libs/$(TARGET_ARCH_ABI)/libv8_base.a
include $(PREBUILT_STATIC_LIBRARY)
include $(CLEAR_VARS)
LOCAL_MODULE := v8_nosnapshot

12:13:41 Build Finished (took 1s.821ms)
As I said, without the attempt to build x86, this is all OK.
Please can anyone point me at where I'm going wrong? Thanks!

I upgraded my source of V8 from 4.1.0.22 to 4.9.385.30 and - after solving a lot of other issues - this problem went away.
