Android:编译libevent动态库并移植jni中，在Android AVD虚拟机上实现一个http服务器

libevent源码：libevent-2.1.8-stable
Android Studio版本：Android Studio Electric Eel | 2022.1.1 Patch 2
AVD虚拟机为x86.

大体步骤：

1.在wsl中编译libevent-2.1.8-stable源码，
2.将编译后的libevent所有内容复制到JNI目录中，编译动态库的时候，有时需要.o文件
F:\AndroidStudioProjects\MyApplication2\JNI
3.在JNI中创建Android.mk， Application.mk两个文件,指定平台是x86。如果用到curl库，也需要用x86
4.在Window powershell中使用ndk-build指令编译动态库，包含libevent.so和jni用到的动态库。注意在编译的动态库的时候会出现大量未定义符合的错误，需要在Android.mk中增加一些.c文件。有时也需要将event-config.h一些不是目标机架构的功能给关掉。要根据编译的平台是x86还是armebi来确定。有些错误还需要修改libevent源码，中间搞得有些头大。哈哈
5.在android studio创建app工程，该工程包含app界面和java调用cpp代码的中间文件。最终在jni中调用cpp文件生成http server。
6.编译android studio工程文件，并运行虚拟机，从AVD的浏览器访问到libevent httpserver,最终可以看到AVD中的目录。

app界面只有一个button,点击后会运行app。
app运行log如下：

AVD浏览器：

下面是一些要注意的细节：

1. 在app同级的build.gradle文件中设置： abiFilters “x86”
2. 查找虚拟机ip地址，并设定服务器绑定ip为虚拟机的本地IP。
   PS F:\Android_Sdk\platform-tools> ./adb devices
   List of devices attached
   emulator-5554 device

PS F:\Android_Sdk\platform-tools> adb -s emulator-5554
Android Debug Bridge version 1.0.41
Version 34.0.1-9680074

PS F:\Android_Sdk\platform-tools> adb -s emulator-5554 shell
root@generic_x86:/ # getprop
[net.gprs.local-ip]: [10.0.2.15]

3. 设置目录为手机的根目录“/”
   evhttp_set_gencb(http, send_document_cb, (void *) “/”);
   在手机的浏览器输入：
   http://10.0.2.15:7777
   可以看到手机中的文件：

4. Android.mk文件如下：
