问题
I am trying to run this project phimp.me.I have used c++_static as per the new document mentioned in android supporting C++ library, still it throws the same error.
I have tried cleaning and rebuilding the project, replacing c++_static with c++_shared but its throws the same error.
Also I tried renaming the OpenCV.mk file to OpenCVX86.mk file as per one link.
I have rechecked and downloaded NDK and CMake from SDK Tools but its stuck with the same error.
Android.mk file
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
OPENCV_INSTALL_MODULES:=on
OPENCV_CAMERA_MODULES:=off
OPENCV_LIB_TYPE := STATIC
include $(LOCAL_PATH)/OpenCV.mk
LOCAL_MODULE := nativeimageprocessing
LOCAL_CFLAGS := -DANDROID_NDK \
-DDISABLE_IMPORTGL
LOCAL_SRC_FILES := main_processing.cpp enhance.cpp filters.cpp colour_space.cpp
LOCAL_C_INCLUDES := $(LOCAL_PATH)/include
LOCAL_LDLIBS += -lm -llog
include $(BUILD_SHARED_LIBRARY)
Application.mk file
APP_STL := c++_static
APP_OPTIM := release
APP_ABI := armeabi-v7a
APP_CPPFLAGS := -frtti -fexceptions
APP_PLATFORM := android-25
Error

*** Android NDK: APP_STL c++_static is no longer supported. Please switch to either c++_static or c++_shared. See https://developer.android.com/ndk/guides/cpp-support.html for more information. . Stop.

Its work for me by this instruction:
Redirect to ndk directory and open ndk-build.cmd file and remove this line
%~dp0\build\ndk-build.cmd %*
really its work for me
of this link: https://github.com/facebook/fresco/issues/47

I'm really not sure how you got that error. I cloned the project and followed the instructions in the README. I got a lot of errors because the project is using an ancient gradle plugin, but those were easily fixed: https://github.com/fossasia/phimpme-android/pull/2684
However, even after dealing with most of those issues, it turns out the project still can't be built with NDK r18 or newer because the project contains prebuilt OpenCV libraries that are built against gnustl. gnustl and libc++ are not ABI compatible, so they cannot be used with libc++, which is the only option in r18+.
Your options for fixing that are:
- Rebuild the OpenCV libraries against libc++.
- Use NDK r17.

On Windows, use the 64-bit NDK instead of 32-bit - this worked for me (verified in r16b)
