Opency官方例程是用glade4.2.1构建的，所以想使用glade7对官方例程重新构建。由于自己对android studio的glade架构不熟悉，走了不少弯路，刚开始使用glade7重新编译opencv官方例程，编译能通过，但是app总是会闪退。
下面这篇文章很有借鉴意义，分享一下：

看完这篇文章重新构建例程后app可以使用了。
1.glade版本：
2.新建工程导入官方例程
修改AndroidManifest.xml
其它需要的资源文件如res,xml按要求copy进来就好。
3.导入官方sdk，重新命名为libopencv,并设置为app的module依赖
4.重新写project的settings.gradle
5.重新写project的build.gradle
6.重新写app的build.gradle
下面是glade文件源码，保存一下大家不用看。
settings.gradle：
pluginManagement {
repositories {
google()
mavenCentral()
gradlePluginPortal()
}
}
dependencyResolutionManagement {
repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
repositories {
google()
mavenCentral()
}
}

build.gradle (libopnecv module) ,保持官方sdk没有变
