我正在使用Android Studio 2.3并导致致命错误:找不到'opencv2 / core / core.hpp'文件
我看到许多类似的问题没有构建Android.mk,但我的Android.mk应该已经构建。
如果更改包含Android.mk中OpenCV.mk的路径,它将报告文件未找到错误,因此我认为Android.mk已包含在构建过程中且文件路径正确。
如果包含路径正确,OpenCV.mk应该找到文件夹opencv2但我仍然找不到文件错误。
有没有其他方法可以在Android Studio中设置包含路径?
我的构建脚本出了什么问题?
本机lib.cpp
#include <DetectionBasedTracker.h>
#include <opencv2/core/core.hpp>
#include <opencv2/contrib/detection_based_tracker.hpp>
Android.mk
LOCAL_PATH := $(call my-dir)
OPENCV_CAMERA_MODULES:=off
OPENCV_INSTALL_MODULES:=on
OPENCV_LIB_TYPE:=SHARED
include $(LOCAL_PATH)/../../../../../../../../OpenCV-android-sdk/sdk/native/jni/OpenCV.mk
LOCAL_C_INCLUDES+=$(LOCAL_PATH)/../../../../../../../../OpenCV-android-sdk/sdk/native/jni/include/
LOCAL_SRC_FILES := native-lib.cpp
LOCAL_LDLIBS += -llog -ldl
LOCAL_MODULE:= native-lib
include $(BUILD_SHARED_LIBRARY)
Application.mk
APP_STL := gnustl_static
APP_CPPFLAGS := -frtti -fexceptions
APP_ABI := armeabi armeabi-v7a arm64-v8a
的build.gradle
android {
......
......
sourceSets.main {
jni.srcDirs = [] //disable automatic ndk-build call
}
task ndkBuild(type: Exec, description: 'Compile JNI source via NDK') {
commandLine 'F:\\Android_SDK\\ndk-bundle\\ndk-build.cmd',
'-C', file('src\\main\\jni').absolutePath,
'NDK_DEBUG=1',
'V=1'
}
tasks.withType(JavaCompile) {
compileTask -> compileTask.dependsOn ndkBuild
}
}
文件结构如下
app/src/main/jni/Android.mk
app/src/main/jni/Application.mk
app/src/main/jni/native-lib.cpp
app/build.gradle
答案 0 :(得分:0)
您是否将OpenCV Library导入为模块?您可以在 Android.mk 文件
中尝试这样做吗?LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
#opencv
OPENCVROOT:= F:/Android/Libs/OpenCV
OPENCV_CAMERA_MODULES:=on
OPENCV_INSTALL_MODULES:=on
OPENCV_LIB_TYPE:=SHARED
include ${OPENCVROOT}/sdk/native/jni/OpenCV.mk
LOCAL_SRC_FILES := native-lib.cpp
LOCAL_LDLIBS += -llog
LOCAL_MODULE := MyOpenCVLibs
include $(BUILD_SHARED_LIBRARY)
在命令行下的 build.gradle 中,您可以像这样添加
commandLine "F:\\Android\\NDK\\android-ndk-r14\\build\\ndk-build.cmd",
'NDK_PROJECT_PATH=build/intermediates/ndk',
'NDK_LIBS_OUT=src/main/jniLibs',
'APP_BUILD_SCRIPT=src/main/jni/Android.mk',
'NDK_APPLICATION_MK=src/main/jni/Application.mk'
