• Unity Android 接入高德定位SDK

    Unity版本 2020

    第一步首先去高德开放平台注册账号然后申请Key

    高德开放平台 | 高德地图API

    注册好账号之后 点击控制台 然后选择管理key 新建一个应用 

     选择添加  然后创建一个key 选择Android平台  SHA1码获取方式参考我的另一篇博客

    Android 签名文件.keystore转换.jks_小张不爱写代码的博客-CSDN博客_keystore转jks

     然后直接创建key即可

    创建完毕之后去下载定位SDK

    相关下载-Android 定位SDK | 高德地图API

    打开Unity创建一个Unity项目

    并创建如下脚本

    1. using UnityEngine;
    2. using UnityEngine.UI;
    3.  
    4. public class Sdk : MonoBehaviour
    5. {
    6.     public Text t;
    7.     private AndroidJavaClass jc;
    8.     private AndroidJavaObject jo;
    9.     private void Awake()
    10.     {
    11.         if (Application.platform == RuntimePlatform.Android)
    12.         {
    13.             jc = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
    14.             jo = jc.GetStatic("currentActivity");
    15.         }
    16.     }
    17.  
    18.     public void StartAMap()
    19.     {
    20.         switch (Application.platform)
    21.         {
    22.             case RuntimePlatform.Android:
    23.                 jo.Call("StartAMap");
    24.                 break;
    25.             default:
    26.                 StopAMapCallBack();
    27.                 break;
    28.         }
    29.     }
    30.  
    31.     public void StopAMap()
    32.     {
    33.         switch (Application.platform)
    34.         {
    35.             case RuntimePlatform.Android:
    36.                 jo.Call("StopAMap");
    37.                 break;
    38.             default:
    39.                 break;
    40.         }
    41.     }
    42.     public void StartAMapCallBack(string msg)
    43.     {
    44.         t.text = msg;
    45.     }
    46.  
    47.     public void StopAMapCallBack()
    48.     {
    49.         t.text = "1111";
    50.     }
    51. }

    然后创建如下结构 Button点击事件分别指向StartAMap和StopAMap即可

     然后直接出包导出AndroidStudio项目

    导出完成之后 现在AS工程中的Libs文件夹中放入解压的高德SDK jar包

     导入之后在如图位置写入如下代码

    implementation fileTree(dir: 'libs', include: ['*.jar'])

    在AndroidManifest.xml上面写入如下权限

    1.   
    2.   <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    3.   
    4.   <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    5.   
    6.   <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    7.   
    8.   <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    9.   
    10.   <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
    11.   
    12.   <uses-permission android:name="android.permission.INTERNET" />
    13.   
    14.   <uses-permission android:name="android.permission.READ_PHONE_STATE" />
    15.   
    16.   <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"
    17.       tools:ignore="ScopedStorage" />
    18.   
    19.   <uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS" />
    20.   
    21.   <uses-permission android:name="android.permission.FOREGROUND_SERVICE"/>
    22.   
    23.   <uses-permission android:name="android.permission.ACCESS_BACKGROUND_LOCATION"/>
    24.  
    25.   <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"
    26.       tools:ignore="ScopedStorage" />

    在AndroidManifest.xml的Application节点内写入如下内容

    1.   <meta-data
    2.      android:name="com.amap.api.v2.apikey"
    3.      android:value="6c8580a005a4f6d162f59e17ace1fbca" />
    4.   <service android:name="com.amap.api.location.APSService" />

    打开UnityPlayerActivity脚本 在末尾加入如下代码 用以动态申请权限

    1. //权限管理
    2. private static final String[] PERMISSIONS =
    3. {
    4.     Manifest.permission.INTERNET,
    5.     Manifest.permission.ACCESS_COARSE_LOCATION,
    6.     Manifest.permission.ACCESS_FINE_LOCATION,
    7.     Manifest.permission.ACCESS_NETWORK_STATE,
    8.     Manifest.permission.ACCESS_WIFI_STATE,
    9.     Manifest.permission.CHANGE_WIFI_STATE,
    10.     Manifest.permission.READ_PHONE_STATE,
    11.     Manifest.permission.ACCESS_LOCATION_EXTRA_COMMANDS,
    12.     Manifest.permission.BLUETOOTH,
    13.     Manifest.permission.BLUETOOTH_ADMIN,
    14. };
    15. private static final int PERMISSIONS_CODE = 1;
    16. //申请权限
    17. private void requestPermission()
    18. {
    19.     // 当API大于 23 时，才动态申请权限
    20.     if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M)
    21.     {
    22.         ActivityCompat.requestPermissions(this,PERMISSIONS,PERMISSIONS_CODE);
    23.     }
    24. }
    25.  
    26. @Override
    27. public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults)
    28. {
    29.     super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    30.     switch (requestCode) {
    31.         case PERMISSIONS_CODE:
    32.             //权限请求失败
    33.             for(int i=0;i1;i++)
    34.             {
    35.                 if(grantResults[i] != PackageManager.PERMISSION_GRANTED)
    36.                 {
    37.                     Log.e("Permissions", "onRequestPermissionsResult: 权限请求失败:"+permissions[i].toString());
    38.                 }
    39.             }
    40.             break;
    41.     }
    42. }

    然后在UnityPlayerActivity脚本中的OnCreate方法中调用requestPermission方法来申请权限

    新创建一个类 写入如下代码

    1. package com.unity3d.player.GaoDe;
    2. import android.util.Log;
    3. import com.amap.api.location.AMapLocation;
    4. import com.amap.api.location.AMapLocationClient;
    5. import com.amap.api.location.AMapLocationClientOption;
    6. import com.amap.api.location.AMapLocationListener;
    7. import com.unity3d.player.UnityPlayer;
    8. import com.unity3d.player.UnityPlayerActivity;
    9.  
    10. public class GaoDe {
    11.     private static GaoDe instance = null;
    12.     private static UnityPlayerActivity ccActivity = null;
    13.  
    14.     public static GaoDe Ins() {
    15.         if (instance == null) {
    16.             instance = new GaoDe();
    17.         }
    18.         return instance;
    19.     }
    20.     //声明AMapLocationClient类对象
    21.     public AMapLocationClient mLocationClient = null;
    22.     //声明定位回调监听器
    23.     public AMapLocationListener mLocationListener = null;
    24.     //声明AMapLocationClientOption对象
    25.     public AMapLocationClientOption mLocationOption = null;
    26.  
    27.     public void Init(UnityPlayerActivity act){
    28.         ccActivity =  act;
    29.         //初始化定位
    30.         AMapLocationClient.updatePrivacyShow(ccActivity, true, true);
    31.         AMapLocationClient.updatePrivacyAgree(ccActivity, true);
    32.         try {
    33.             //初始化定位
    34.             mLocationClient = new AMapLocationClient(ccActivity);
    35.         }catch (Exception e){
    36.             e.printStackTrace();
    37.             Log.d("Unity", "UnityPlayerActivity Init error: "+e);
    38.         }
    39.         //初始化AMapLocationClientOption对象
    40.         mLocationOption = new AMapLocationClientOption();
    41.         //设置定位监听
    42.         mLocationListener = new AMapLocationListener() {
    43.             @Override
    44.             public void onLocationChanged(AMapLocation aMapLocation) {
    45.                 OnLocationChanged(aMapLocation);
    46.             }
    47.         };
    48.         //设置定位回调监听
    49.         mLocationClient.setLocationListener(mLocationListener);
    50.         //设置定位模式为AMapLocationMode.Hight_Accuracy，高精度模式。
    51.         mLocationOption.setLocationMode(AMapLocationClientOption.AMapLocationMode.Hight_Accuracy);
    52.         //设置定位间隔,单位毫秒,默认为2000ms，最低1000ms。
    53.         mLocationOption.setInterval(1000);
    54.         //单位是毫秒，默认30000毫秒，建议超时时间不要低于8000毫秒。
    55.         mLocationOption.setHttpTimeOut(8000);
    56.         //优先使用gps
    57.         mLocationOption.setGpsFirst(true);
    58.         Log.d("Unity", "高德: InitOK");
    59.     }
    60.  
    61.     private void OnLocationChanged(AMapLocation amapLocation){
    62.         Log.d("Unity", "高德: OnLocationChanged");
    63.         if(amapLocation == null) {
    64.             amapLocation = mLocationClient.getLastKnownLocation();
    65.         }
    66.         if (amapLocation != null)
    67.         {
    68.             Log.e("AmapError", "amapLocation~=null start:");
    69.             mLocationClient.stopLocation();
    70.             int errorCode = amapLocation.getErrorCode();
    71.             Log.e("AmapError", "amapLocation~=null errorCode:"+errorCode);

    73.             int locationType = amapLocation.getLocationType();//获取当前定位结果来源，如网络定位结果，详见定位类型表
    74.             double longitude = amapLocation.getLongitude();//获取经度
    75.             double latitude = amapLocation.getLatitude();//获取纬度
    76.             String address = amapLocation.getAddress();
    77.             String country = amapLocation.getCountry();
    78.             String province = amapLocation.getProvince();
    79.             String city = amapLocation.getCity();
    80.             String district = amapLocation.getDistrict();
    81.             String re = errorCode + "|" + longitude + "|" + latitude + "|" + address +"|"+ country +"|"+ province +"|"+ city +"|"+ district+"  errrrrrrr";
    82.             Log.e("AmapError", "amapLocation~=null 位置信息:"+re);
    83.             UnityPlayer.UnitySendMessage("Main Camera", "StartAMapCallBack", re);
    84.         }
    85.         else
    86.         {
    87.             //定位失败时，可通过ErrCode（错误码）信息来确定失败的原因，errInfo是错误信息，详见错误码表。
    88.             Log.e("AmapError","location Error, ErrCode:"
    89.                     + amapLocation.getErrorCode() + ", errInfo:"
    90.                     + amapLocation.getErrorInfo());
    91.             mLocationClient.stopLocation();
    92.             UnityPlayer.UnitySendMessage("Main Camera", "StartAMapCallBack", "0|0|0");
    93.         }
    94.     }
    95.  
    96.     //开始定位
    97.     public void StartAMap()
    98.     {
    99.         if(mLocationClient!=null) {
    100.             //给定位客户端对象设置定位参数
    101.             mLocationClient.setLocationOption(mLocationOption);
    102.             //启动定位
    103.             mLocationClient.startLocation();
    104.             Log.d("Unity", "StartAMap: 已开启定位");
    105.         }
    106.         else{
    107.             if(ccActivity!=null)
    108.                 Init(ccActivity);
    109.             else
    110.                 Log.d("Unity", "StartAMap: mLocationClient是空的");
    111.         }
    112.     }
    113.  
    114.     //停止定位
    115.     public void StopAMap()
    116.     {
    117.         if(mLocationClient!=null) {
    118.             mLocationClient.stopLocation();
    119.             mLocationClient.onDestroy();
    120.             mLocationOption = null;
    121.             mLocationListener = null;
    122.             UnityPlayer.UnitySendMessage("Main Camera", "StopAMapCallBack","");
    123.         }
    124.     }
    125. }

    打开UnityPlayerActivity脚本在最末尾加入如下代码 在OnCreate申请权限下面调用

    GaoDe.Ins().Init(this); 用以初始化SDK

    1. public void StartAMap(){
    2.     GaoDe.Ins().StartAMap();
    3. }
    4.  
    5. public void StopAMap()
    6. {
    7.     GaoDe.Ins().StopAMap();
    8. }

    然后就可以打包apk进行测试了  出现如下结果即可
