我是一个android开发人员，但我是新的Android NDK，请帮助，或告诉我你还需要什么/你将如何尝试解决这种类型的问题。编译dlib和opencv与android ndk
我用this dlib为android例子和官方opencv for android library，我想将两者集成到一个应用程序中。当我试图建立的项目，我得到以下错误：
FAILURE: Build failed with an exception.
* What went wrong:

我的第一个猜测是，我的天堂/吨列入我Android.mk的source.cpp但placeing到src的文件并没有解决象征。 这里是我的Android.mk：
LOCAL_PATH := $(call my-dir)
## Build dlib to static library
include $(CLEAR_VARS)
LOCAL_MODULE := dlib
LOCAL_C_INCLUDES := $(LOCAL_PATH)/dlib
LOCAL_SRC_FILES += \
$(LOCAL_PATH)/dlib/dlib/all/source.cpp \
$(LOCAL_PATH)/dlib//dlib/threads/threads_kernel_shared.cpp \
$(LOCAL_PATH)/dlib/dlib/entropy_decoder/entropy_decoder_kernel_2.cpp \
$(LOCAL_PATH)/dlib/dlib/base64/base64_kernel_1.cpp \
$(LOCAL_PATH)/dlib/dlib/threads/threads_kernel_1.cpp \
$(LOCAL_PATH)/dlib/dlib/threads/threads_kernel_2.cpp
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_C_INCLUDES)
include $(BUILD_STATIC_LIBRARY)
# Build opencv
include $(CLEAR_VARS)
OPENCVROOT := ~/Android/openCV/OpenCV-android-sdk
OPENCV_CAMERA_MODULES:=on
OPENCV_INSTALL_MODULES:=on
OPENCV_LIB_TYPE := SHARED
include ${OPENCVROOT}/sdk/native/jni/OpenCV.mk
LOCAL_MODULE := detection_based_tracker
LOCAL_C_INCLUDES += $(LOCAL_PATH)
LOCAL_SRC_FILES := DetectionBasedTracker_jni.cpp
LOCAL_LDLIBS += -lm -llog -ldl -lz -ljnigraphics
LOCAL_CPPFLAGS += -fexceptions -frtti -std=c++11
# LOCAL_STATIC_LIBRARIES += dlib
include $(BUILD_SHARED_LIBRARY)
也许NDK_PROJECT_PATH=null是什么问题？为什么两个图书馆分开建造？或者还有什么可以解决的问题？我尝试了很多修改Android.mk，但它对我来说是一个谜。 任何帮助或意见将是有用的。
编辑：
当我注释掉LOCAL_STATIC_LIBRARIES += dlib行，我有以下异常：
Build command failed.

你真的需要MIPS构建吗？如果您打算在ARM设备上运行您的应用程序，请将** abiFilters =“armeabi_v7a”**添加到您的** build.gradle **脚本中。 –
我在abi arm64-v8a上运行，但我也在修改本地C++代码，所以我想我还需要构建它。 – bendaf
您不应该评论'LOCAL_STATIC_LIBRARIES + = dlib' –
