Opencv 错误：ErorAndroid/sdk/ndk bundle/ndk build.cmd''；以非零退出值2结束

我在我的项目中使用androidndk，每当我想构建我的项目时，它都会显示这个错误

错误：任务“：app:ndkBuild”的执行失败。进程命令 'E:/Android/sdk/ndk bundle/ndk build.cmd''以非零退出完成 价值2

我已经创建了android.mk和application.mk

应用程序.mk

APP_STL := gnustl_static
APP_CPPFLAGS := -frtti -fexceptions
APP_ABI := armeabi-v7a
APP_PLATFORM := android-16

检查您在gradle–本地属性中添加的内容

android.useDeprecatedNdk = true 

然后在此之后，当您构建项目时，您会收到构建成功的消息。 对于详细的流程，请确保您正确地遵循了成功安装Android的步骤

NDK构建环境。

我已经解决了我的问题，我对android.mk或android.application没有问题，这是我的错，我对我的cpp文件和.h文件犯了一些错误，所以现在它工作正常了
