Android下怎么发布纯C/C++的应用

Android上如何发布纯C/C++的应用
我下载了NDK，里面sapmles目录下有个“native-activity”的demo，请问这个demo编译后如何安装到android手机上，“hello-jni”这个demo我安装运行是可以的，但它是通过Java代码调用的，我想问下能否不通过JNI，直接将纯C++应用部署的手机上运行，求步骤，先说声谢谢！
另外，“native-activity”这个demo的代码中有个名为void android_main(struct android_app* state) 的函数，注释说，这个是程序入口，请问这个是不是android上的main函数，程序要怎么编译或配置后才能调用这个入口：

C/C++ code

/** * This is the main entry point of a native application that is using * android_native_app_glue.  It runs in its own thread, with its own * event loop for receiving input events and doing other things. */void android_main(struct android_app* state) {

HTML code

Note however that is is possible to write a sophisticated application innative code with a small "application wrapper" used to start/stop itappropriately.
