java - Android Studio 在新项目上从 C++ 支持开始会出现多个错误？

Question

当我启动一个支持 C++ 的新项目时，新创建的项目无法识别主 Activity 中的 native Jni 函数。打开我的 native-lib.cpp这些错误如图所示出现

在运行项目时我遇到这些错误

 Build command failed.
Error while executing process C:\Users\abc\AppData\Local\Android\Sdk\cmake\3.10.2.4988404\bin\cmake.exe with arguments {--build D:\2019 android\OPENCV3\app\.externalNativeBuild\cmake\debug\x86 --target native-lib}
Unknown argument android\OPENCV3\app\.externalNativeBuild\cmake\debug\x86
Usage: cmake --build <dir> [options] [-- [native-options]]
Options:
  <dir>          = Project binary directory to be built.
  --target <tgt> = Build <tgt> instead of default targets.
                   May only be specified once.
  --config <cfg> = For multi-configuration tools, choose <cfg>.
  --clean-first  = Build target 'clean' first, then build.
                   (To clean only, use --target 'clean'.)
  --use-stderr   = Ignored.  Behavior is default in CMake >= 3.0.
  --             = Pass remaining options to the native tool.

只需将 D:\2019 android 重命名为 D:\2019_android，所有烦恼都会迎刃而解。
