这里，用了一个比较偷懒的办法，直接用高德提供的android定位sdk，没有重新编译。好处是省事，坏处是，没法修改默认的定位模式。部分信息获取不到。
如果需要完整的功能，还是需要重新编译高德地图的sdk。
unity3d 5.3.2
高德android 定位 sdk 2.3
首先，注册高德sdk的用户，并且获取key。这里的key和编译环境的sha1相关。
新建一个unity项目
先把项目编译成android，记得Bundle Identifier必须和高德key里面的pakage一致。
用apk逆向工具把编译好的apk文件解开，
找到cert.rsa，用命令行获取调式用的sha1。官方只提供了android studio调式用的sha1获取的办法。
keytool -printcert -file cert.rsa
下载sdk包
把下载的jar和逆相出来的AndroidManifest.xml导入到unity工程的Plugins/Android目录下
修改AndroidManifest.xml文件

做个简单的界面
添加类AmapEvent，将android的事件转化成unity的事件
using UnityEngine;
using System.Collections;
public class AmapEvent : AndroidJavaProxy {
public AmapEvent ()
: base ("com.amap.api.location.AMapLocationListener")
{
}
void onLocationChanged (AndroidJavaObject amapLocation)
{
if (locationChanged != null) {
locationChanged (amapLocation);
}
}
public delegate void DelegateOnLocationChanged(AndroidJavaObject amap);
public event DelegateOnLocationChanged locationChanged;
}
添加locationmange类，调用高德的sdk。定位时间和定位速度无法获取到，会报错。似乎在android studio里可以。
using UnityEngine;
using System.Collections;
using System;
using UnityEngine.UI;
public class LocationManage : MonoBehaviour

编译以后，运行，结果如下
