2012-12-12 下载ndk编译出so和可执行文件，放到android 真机运行，包含源码。
2023-12-13 05:25:25
一、下载ndk链接NDK 下载 ?|? Android NDK ?|? Android Developers
二、解压ndk后得到下面的文件，里面包含ndk-build.cmd，这个是用来编译的。
三、Android.mk和C源码。完整源码下载路径https://download.csdn.net/download/qq_37858386/88622702

四、使用ndk-build.cmd编译C源码成so和可执行文件。
五、push到android 真机去运行
