编译 && 运行

我们把 android-ndk-r19c 放置到 D:\android-ndk-r19c 这个位置，然后把 hello-exe 目录放到这里。然后我们 CMD 打开命令行窗口，切换到D:\android-ndk-r19c\hello-exe\jni，使用 ..\..\ndk-build.cmd -B V=1 执行，会看到如下内容：

 

Android NDK: APP_PLATFORM not set. Defaulting to minimum supported version android-16.

这里专门把编译过程打印了出来（ V=1 ）。跟这个差不多的是 --just-print 参数，不过 --just-print 是只打
