编译libevent android版本动态库

libevent编译成android动态库较为麻烦，下面来详细介绍整个编译过程。

1. 下载libevent源码（最好源码版本和本教程保持一致）

https://github.com/libevent/libevent/releases/download/release-2.1.8-stable/libevent-2.1.8-stable.tar.gz

2. 下载android交叉编译工具ndk（不挂链接，自行百度安装）

3. 编译mk文件

Android.mk

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_ARM_MODE := arm
LOCAL_MODULE := libevent
ANDROID := true
LIB_SRC := \
event.c \
           evthread.c \
           buffer.c \
           bufferevent.c \
           bufferevent_filter.c \
           bufferevent_pair.c \
           listener.c \
           bufferevent_ratelim.c \
           evmap.c \
           log.c \
           evutil.c \
           evutil_rand.c \
		   evutil_time.c \
           select.c \
           poll.c \
           epoll.c \
           signal.c \
           event_tagging.c \
           http.c \
           evdns.c \
           evrpc.c \
           bufferevent_sock.c \
		   strlcpy.c 

LOCAL_SRC_FILES  := $(LIB_SRC)
LOCAL_C_INCLUDES := $(LOCAL_PATH)/include \
                    $(LOCAL_PATH)/compat
LOCAL_CFLAGS += -pie -fPIE -static -fPIC
include $(BUILD_SHARED_LIBRARY)

Application.mk

APP_STL      := c++_static
APP_CPPFLAGS := -frtti -std=c++11
APP_ABI      := armeabi-v7a arm64-v8a
APP_BUILD_SCRIPT := Android.mk

4. 修改配置文件event2/event-config.h,如果没有就新建一个

修改成如下：

/* event2/event-config.h
 *
 * This file was generated by autoconf when libevent was built, and post-
 * processed by Libevent so that its macros would have a uniform prefix.
 *
 * DO NOT EDIT THIS FILE.
 *
 * Do not rely on macros in this file existing in later versions.

5. 使用ndk命令进行编译

进入源码目录，输入命令

ndk-build.cmd NDK_PROJECT_PATH=. APP_BUILD_SCRIPT=Android.mk

arm64-v8a编译通过
