我正在尝试学习android NDK,我正在遵循http://developer.android.com/sdk/ndk/overview.html上的步骤来构建hello-jni示例。
我已经下载了Android NDK。但是当我尝试通过终端构建或编译代码时,它会显示“command not found”错误。
我正在研究ubuntu。有人可以帮我解决这个问题吗?

构建hello-jni的步骤是:
下载Android NDK并将其解压缩到某个目录(/ opt for me):
接下来,“cd / opt // samples / hello-jni”到示例目录,并输入“/ opt // ndk-build”来构建文件,输出如下:
/opt/android-ndk/samples/hello-jni>/opt/android-ndk/ndk-build

完成。要将输出构建到apk文件,您需要使用Android SDK,请参阅例如:
