一：高德定位有效key的获取
参考官方文档地址：获取有效key的详细流程
注意拿到的key确定是正式的，如果只是测试的话就不能运用到生产环境
二： sdk的使用
1.把下载下来的sdk下的jar包放进unity的Plugins<Android< AMap_Location_V4.2.0_20180809.jar
2.合并配置AndroidManifest 文件，
添加权限：
<?xml version="1.0" encoding="utf-8" standalone="no"?>
<manifest

android:installLocation="preferExternal"

<!-- 设置key值 -->

<!-- 定位需要的服务 -->

</manifest>
设置从高德拿到的key：
三：Unity端代码的使用
两个脚本足以 ：
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class ChangeJavaToC : AndroidJavaProxy
{
public ChangeJavaToC() : 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;
}
using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class LocationManager : MonoBehaviour {
public Text txtLocation;

mLocationClient.Call("setLocationOption", mLocationOption);
amap = new ChangeJavaToC();
amap.locationChanged += OnLocationChanged;
mLocationClient.Call("setLocationListener", amap);
mLocationClient.Call("startLocation");
}
catch (Exception ex)
{
txtLocation.text = ex.Message;
EndLocation();
}
}
public void EndLocation()
{
if (amap != null)
{

}
catch (Exception ex)
{
txtLocation.text = txtLocation.text + "\r\n--------------ex-------------:";
txtLocation.text = txtLocation.text + "\r\n" + ex.Message;
}
}
else
{
txtLocation.text = ">>amaperror:";
txtLocation.text = txtLocation.text + ">>getErrorCode:" + amapLocation.Call<int>("getErrorCode").ToString();
txtLocation.text = txtLocation.text + ">>getErrorInfo:" + amapLocation.Call<string>("getErrorInfo");
