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 versinotallow="1.0" encoding="utf-8" standalnotallow="no"?>
<manifest
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:installLocatinotallow="preferExternal"
  package="自己的包名com.xxx.xxx">
  <supports-screens
    android:anyDensity="true"
    android:largeScreens="true"
    android:normalScreens="true"
    android:smallScreens="true"
    android:xlargeScreens="true"/>

  <uses-permission android:name="android.permission.RECORD_AUDIO" />
  <uses-permission android:name="android.permission.INTERNET" />
  <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
  <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
  <uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />
  <uses-permission android:name="android.permission.READ_PHONE_STATE" />
  <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
  <uses-permission android:name="android.permission.READ_CONTACTS" />
  <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
  <uses-permission android:name="android.permission.WRITE_SETTINGS" />
  <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

  <!--这个权限用于获取wifi的获取权限，wifi信息会用来进行网络定位-->
  <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
  <uses-permission android:name="android.permission.CHANGE_CONFIGURATION" />

  <!-- 请求网络 -->
  <uses-permission android:name="android.permission.INTERNET" />

  <!-- 不是SDK需要的权限，是示例中的后台唤醒定位需要的权限 -->
  <uses-permission android:name="android.permission.WAKE_LOCK" />

  <!-- 需要运行时注册的权限 -->
  <!--用于进行网络定位-->
  <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
  <!--用于访问GPS定位-->
  <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
  <!--用于提高GPS定位速度-->
  <uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS" />
  <!--写入扩展存储，向扩展卡写入数据，用于写入缓存定位数据-->
  <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
  <!--读取缓存数据-->
  <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

  <!--用于读取手机当前的状态-->
  <uses-permission android:name="android.permission.READ_PHONE_STATE" />

  <!-- 更改设置 -->
  <uses-permission android:name="android.permission.WRITE_SETTINGS" />

  <!-- 3.2.0版本增加 -->
  <uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
  <!-- 3.2.0版本增加-->
  <uses-permission android:name="android.permission.BLUETOOTH" />

  <application android:banner="@drawable/app_banner"
               android:debuggable="false"
               android:icnotallow="@drawable/app_icon"
               android:isGame="true"
               android:label="@string/app_name"
               android:theme="@style/UnityThemeSelector">

    <!-- 设置key值 -->
    <meta-data
           android:name="com.amap.api.v2.apikey"
           android:value="自己申请的key" />
    <!-- 定位需要的服务 -->
    <service android:name="com.amap.api.location.APSService" ></service>


    <activity android:cnotallow="locale|fontScale|keyboard|keyboardHidden|mcc|mnc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|touchscreen|uiMode" android:label="@string/app_name" android:launchMode="singleTask" android:name="com.unity3d.player.UnityPlayerActivity" android:screenOrientatinotallow="portrait">
  </application>
</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;
    private ChangeJavaToC amap;
    private AndroidJavaClass jcu;
    private AndroidJavaObject jou;
    private AndroidJavaObject mLocationClient;
    private AndroidJavaObject mLocationOption;

    public void StartLocation()
    {
        try
        {
            jcu = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
            jou = jcu.GetStatic<AndroidJavaObject>("currentActivity");
            mLocationClient = new AndroidJavaObject("com.amap.api.location.AMapLocationClient", jou);
            mLocationOption = new AndroidJavaObject("com.amap.api.location.AMapLocationClientOption");
            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)
        {
            amap.locationChanged -= OnLocationChanged;
        }

        if (mLocationClient != null)
        {
            mLocationClient.Call("stopLocation");
            mLocationClient.Call("onDestroy");
        }

        txtLocation.text = "";
    }

    private void OnLocationChanged(AndroidJavaObject amapLocation)
    {
        if (amapLocation != null)
        {
            if (amapLocation.Call<int>("getErrorCode") == 0)
            {
                txtLocation.text = "成功定位获取数据:";

                try
                {
                    txtLocation.text = txtLocation.text + "\r\n>>定位结果来源:" + amapLocation.Call<int>("getLocationType").ToString();
                    txtLocation.text = txtLocation.text + "\r\n>>纬度:" + amapLocation.Call<double>("getLatitude").ToString();
                    txtLocation.text = txtLocation.text + "\r\n>>经度:" + amapLocation.Call<double>("getLongitude").ToString();

                    txtLocation.text = txtLocation.text + "\r\n>>城区:" + amapLocation.Call<string>("getDistrict").ToString();
                    txtLocation.text = txtLocation.text + "\r\n>>街道:" + amapLocation.Call<string>("getStreet").ToString();
                    txtLocation.text = txtLocation.text + "\r\n>>门牌:" + amapLocation.Call<string>("getStreetNum").ToString();
                    txtLocation.text = txtLocation.text + "\r\n>>城市编码:" + amapLocation.Call<string>("getCityCode").ToString();
                    txtLocation.text = txtLocation.text + "\r\n>>地区编码:" + amapLocation.Call<string>("getAdCode").ToString();
                    txtLocation.text = txtLocation.text + "\r\n>>海拔:" + amapLocation.Call<double>("getAltitude").ToString();
                    txtLocation.text = txtLocation.text + "\r\n>>方向角:" + amapLocation.Call<float>("getBearing").ToString();
                    txtLocation.text = txtLocation.text + "\r\n>>定位信息描述:" + amapLocation.Call<string>("getLocationDetail").ToString();
                    txtLocation.text = txtLocation.text + "\r\n>>兴趣点:" + amapLocation.Call<string>("getPoiName").ToString();

                    txtLocation.text = txtLocation.text + "\r\n>>当前速度:" + amapLocation.Call<float> ("getSpeed").ToString ();  

                }
                catch (Exception ex)
                {
                    txtLocation.text = txtLocation.text + "\r\n--------------ex-------------:";
                    txtLocation.text = txtLocation.text + "\r\n" + ex.Message;
                }

            }
            else
            {

            }
        }
        else
        {

        }
    }
}

真机打包测试
