Windows11搭建Qt6.5.0 for Android+OpenCV4.7.0开发环境

1.下载opencv-4.7.0-android-sdk.zip，下载地址：https://opencv.org/releases/，解压后，如下图：

 

 2.编辑opecv_android.pri，内容如下（可使用命令行命令-dir *.a/ON/B>v8a.txt）：

message('Linux/Andoird is running!')
#data.files += images/*.*
#data.files += dnn/*.prototxt
#data.files += dnn/*.caffemodel
#data.path = /assets/dnn
#INSTALLS += data

# 0.指定应用程序二进制接口（Application Binary Interface）
ANDROID_CPU = arm64-v8a

# 1.定义 OPENCV_ANDROID 目录。
OPENCV_ANDROID = D:/MyProjects/Android/OpenCV/OpenCV-android-sdk/sdk/native

# 2.用来描述构建项目时应该搜索的 include 目录。
INCLUDEPATH += \
$$OPENCV_ANDROID/jni/include \
$$OPENCV_ANDROID/jni/include/opencv2 \

# 3.用来描述项目引用的库文件列表。
LIBS += $$OPENCV_ANDROID/libs/$$ANDROID_CPU/libopencv_java4.so

# OpenCV-android-sdk\sdk\native\staticlibs\$$ANDROID_CPU(15)
NATIVE_STATICLIBS = $$OPENCV_ANDROID/staticlibs/$$ANDROID_CPU
LIBS += \
$$NATIVE_STATICLIBS/libopencv_calib3d.a \
$$NATIVE_STATICLIBS/libopencv_core.a \
$$NATIVE_STATICLIBS/libopencv_dnn.a \
$$NATIVE_STATICLIBS/libopencv_features2d.a \
$$NATIVE_STATICLIBS/libopencv_flann.a \
$$NATIVE_STATICLIBS/libopencv_gapi.a \
$$NATIVE_STATICLIBS/libopencv_highgui.a \
$$NATIVE_STATICLIBS/libopencv_imgcodecs.a \
$$NATIVE_STATICLIBS/libopencv_imgproc.a \
$$NATIVE_STATICLIBS/libopencv_ml.a \
$$NATIVE_STATICLIBS/libopencv_objdetect.a \
$$NATIVE_STATICLIBS/libopencv_photo.a \
$$NATIVE_STATICLIBS/libopencv_stitching.a \
$$NATIVE_STATICLIBS/libopencv_video.a \
$$NATIVE_STATICLIBS/libopencv_videoio.a

# OpenCV-android-sdk\sdk\native\3rdparty\libs\$$ANDROID_CPU(13)
NATIVE_3RDPARTY = $$OPENCV_ANDROID/3rdparty/libs/$$ANDROID_CPU
LIBS += \
$$NATIVE_3RDPARTY/libade.a \
$$NATIVE_3RDPARTY/libcpufeatures.a \
$$NATIVE_3RDPARTY/libIlmImf.a \
$$NATIVE_3RDPARTY/libittnotify.a \
$$NATIVE_3RDPARTY/liblibjpeg-turbo.a \
$$NATIVE_3RDPARTY/liblibopenjp2.a \
$$NATIVE_3RDPARTY/liblibpng.a \
$$NATIVE_3RDPARTY/liblibprotobuf.a \
$$NATIVE_3RDPARTY/liblibtiff.a \
$$NATIVE_3RDPARTY/liblibwebp.a \
$$NATIVE_3RDPARTY/libquirc.a \
$$NATIVE_3RDPARTY/libtbb.a \
$$NATIVE_3RDPARTY/libtegra_hal.a

contains(ANDROID_TARGET_ARCH, $$ANDROID_CPU) {
ANDROID_EXTRA_LIBS = \
$$OPENCV_ANDROID/libs/$$ANDROID_CPU/libopencv_java4.so
}

3.在项目文件.pro中引入.pri文件

#Linux/Andoird操作系统
unix: !mac {
OPENCV = $$(OPENCV_QT)
isEmpty(OPENCV) {
error(OPENCV_QT does not exist!!!)
}
include($$(OPENCV_QT)opencv_android.pri)
}

#macOS操作系统
unix: mac {
message('macOS is running!')
INCLUDEPATH += /path/to/opencv/include/opencv4
LIBS += -L/path/to/opencv/lib -lopencv_world
}

#Windows操作系统（...,win8,win10...）的桌面应用程序
win32 {
OPENCV = $$(OPENCV_QT)
isEmpty(OPENCV) {
error(OPENCV_QT does not exist!!!)
}
include($$(OPENCV_QT)opencv_win32.pri)
}

4.正确配置后，.so库会添加到项目中：

 5.若使用相机，请在.pro文件添加：QT += quick multimedia，否则，将没有手机权限！！！
