我在
Android应用程序中通过JNI使用OpenCV.
libopencv_java.so太大了,大约7M.显然,我只需要几个库.
我检查OpenCV4Android中的libs,找出一些静态库,比如libopencv_core.a
这是我在Android.mk中的新代码,包含必要的OpenCV库.我包括libopencv_core.a,libopencv_highgui.a,libopencv_imgproc.a和一些第三方库,它们是：liblibjasper.a,liblibjpeg.a,liblibpng.a,liblibtiff.a @H_301_5@include $(CLEAR_VARS) LOCAL_MODULE := libopencv_highgui_prebuilt LOCAL_SRC_FILES := libopencv_highgui.a LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/OpenCV242AndroidSDKNativeJNI/include include $(PREBUILT_STATIC_LIBRARY) include $(CLEAR_VARS) LOCAL_MODULE := libopencv_imgproc_prebuilt LOCAL_SRC_FILES := libopencv_imgproc.a LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/OpenCV242AndroidSDKNativeJNI/include include $(PREBUILT_STATIC_LIBRARY) include $(CLEAR_VARS) LOCAL_MODULE := libopencv_core_prebuilt LOCAL_SRC_FILES := libopencv_core.a LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/OpenCV242AndroidSDKNativeJNI/include include $(PREBUILT_STATIC_LIBRARY) include $(CLEAR_VARS) LOCAL_MODULE := liblibjpeg_prebuilt LOCAL_SRC_FILES := liblibjpeg.a LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/OpenCV242AndroidSDKNativeJNI/include include $(PREBUILT_STATIC_LIBRARY) include $(CLEAR_VARS) LOCAL_MODULE := liblibpng_prebuilt LOCAL_SRC_FILES := liblibpng.a LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/OpenCV242AndroidSDKNativeJNI/include include $(PREBUILT_STATIC_LIBRARY) include $(CLEAR_VARS) LOCAL_MODULE := liblibtiff_prebuilt LOCAL_SRC_FILES := liblibtiff.a LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/OpenCV242AndroidSDKNativeJNI/include include $(PREBUILT_STATIC_LIBRARY) include $(CLEAR_VARS) LOCAL_MODULE := liblibjasper_prebuilt LOCAL_SRC_FILES := liblibjasper.a LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/OpenCV242AndroidSDKNativeJNI/include include $(PREBUILT_STATIC_LIBRARY) include $(CLEAR_VARS) LOCAL_MODULE := native_jni LOCAL_SRC_FILES := jni_part.cpp LOCAL_CFLAGS += -fpermissive LOCAL_STATIC_LIBRARIES += libopencv_highgui_prebuilt LOCAL_STATIC_LIBRARIES += libopencv_imgproc_prebuilt LOCAL_STATIC_LIBRARIES += libopencv_core_prebuilt LOCAL_STATIC_LIBRARIES += liblibjpeg_prebuilt LOCAL_STATIC_LIBRARIES += liblibpng_prebuilt LOCAL_STATIC_LIBRARIES += liblibtiff_prebuilt LOCAL_STATIC_LIBRARIES += liblibjasper_prebuilt LOCAL_LDLIBS += -llog -ldl LOCAL_LDLIBS += -ljnigraphics LOCAL_LDLIBS += -lz include $(BUILD_SHARED_LIBRARY)

但它没有经过编译.一个长错误列表,所有与断言相关的失败：

有什么建议吗？
