找遍了全网，没有一个完整的可用的框架。ndk自带的android_native_app_glue确实不太好用，闭关几天，写出了一个框架。完全的消息队列调用，目前测试的主体框架是没有什么问题了，程序入口还是android_main。调用过程：
void android_main(android_app* app)
{
//APP_LOG("main : 程序启动");
//设置消息回调函数，就一个，整体和win32编程差不多了。
app->onEvent = on_app_event;
//循环等待事情以进行处理。
while (app->running){//app处于运行状态
app->process_message();//处理消息主函数
if(!app->pause()){
//draw_frame();//绘制我们的游戏，相当于MainLoop事件
}
else{
//APP_LOG("PAUSE");
}
}
//APP_LOG("main : 程序结束");
}
消息事件结构：
#pragma pack(push, 1)
struct APP_EVENT
{
int id;
union{
void* data;
struct{//input motion
int16_t x, y, z, w;
};
struct{//input_keyboard
int32_t key;
int32_t flag;
};
struct{//ARect
int16_t left, top, right, bottom;
};
};
};
#pragma pack(pop)
主消息处理函数，完全防win32编程设计，当然，事件处理做的还不够全面。现在只是初期框架，但这个框架已经比glue那个清晰多了。
主消息回调函数：
void on_app_event(android_app* app, APP_EVENT& event)
{
switch(event.id)
{
case APP_START://activity启动
break;
case APP_STOP://停止
break;
case APP_RESUME://返回
break;
case APP_PAUSE://暂停
break;
case APP_DESTROY://销毁退出
break;
case APP_SAVE://保存状态
break;
case APP_WINDOW_CREATE://窗口创建，app->window有效
break;
case APP_WINDOW_CLOSE://窗口销毁
break;
case APP_WINDOW_ACTIVATE://窗口获得焦点
break;
case APP_WINDOW_DEACTIVATE://窗口失去焦点
break;
case APP_WINDOW_RESIZE://窗口大小改变
break;
case APP_TOUCH_DOWN://触摸按下
//这三个事件，都使用event.x, event.y作为坐标
//event.z代表pointerid
break;
case APP_TOUCH_MOVE://触摸滑动
break;
case APP_TOUCH_UP:
break;
default:
//APP_LOG("unknow msg:%d", cmd);
break;
}
}
ndk的activity入口函数其实是：
void ANativeActivity_onCreate(ANativeActivity* activity, void* savedState, size_t savedStateSize);
这个函数由主进程调用，主进程创建一个activity，通知native库创建环境并处理，如果这个函数不返回，app就会卡死无响应。所以我们native库的过程要在一个新的线程里面处理。直接使用主线程的回调也不是不可以，但无法处理MainLoop这个事件，这个事件主线程没给。如果新建一个线程，如何处理主线程回调的事件，就是一个根本的问题。glue库用了pipe，并大把大把的mutex lock处理。下面这个库，把lock基本都去掉了，不再使用ALooper进行消息处理。主线程和线程之间的通信还是用的pipe，因为简单易用。
方式很简单：（执行标准）
一：所有ANativeActivity_onCreate里面指定的回调函数，执行过程都在主线程里面，这个我们要打包。用APP_EVENT把事件封装，通过pipe发送到我们线程的事件队列，不对android_app内部数据进行操作。
二：android_main()过程里面，循环执行process_message()，进行事件处理。process_message()的执行过程就是，从pipe里面读取打包的APP_EVENT，并进行预处理、回调执行、后续处理。
三：所有事件方法，过程尽量保证清晰，可读性高。
目前库封装了部分输入交互操作，后续会继续封装。也欢迎大家评论，有用的着的尽可拿去用，public domain协议！
